Artificial Intelligence-based Innovations

Trinitas HORIZON – Transforming healthcare delivery through improved complaint-driven, personalized, and AI supported trustworthy diagnostic pathways in primary care (Project duration 2027 - 2037)

Healthcare in the Netherlands is under growing pressure due to an ageing population, more people with multiple conditions, and rising demand for diagnostics. This makes it harder for GPs to identify what diagnostic trajectory patients need quickly and accurately. The Trinitas HORIZON project will develop an AI-supported diagnostic platform that brings together all patient information and helps GPs make better decisions faster. By enabling a “first-time-right” diagnosis, the platform aims to reduce unnecessary testing, shorten waiting times, and keep healthcare accessible, affordable, and effective for both patients and professionals.

Broad national collaboration

Trinitas HORIZON is led by UMC Utrecht (Dr. S. Haitjema) and brings together a broad national network. Dutch university medical centres and their departments of general practice are involved, alongside GP organizations, hospitals, first-line care organizations, patient organizations, universities, technology partners and experts in social, ethical and legal aspects of healthcare innovation.

This broad collaboration is intended to ensure that the technology is developed with the practice of healthcare in mind from the start. GPs, specialists, researchers, data experts and societal partners will work together to design, test and evaluate solutions that can be used in real-world settings.

AI-based Diagnosis Engine

Within this consortium, our work package focuses on the development of the AI-based Diagnosis Engine (AIDE). AIDE will combine computational and mathematical models for diagnostic analysis and decision support, helping healthcare professionals in navigating increasingly complex diagnostic pathways. The work builds on our expertise in explainable AI and clinical decision support, extending methodologies developed within our group to broader healthcare challenges beyond oncology.

In addition, we contribute to the development of user-friendly interactive software that enables healthcare professionals to use AIDE effectively in daily practice.

Trinitas HORIZON is co-funded through the NWO-KIC programme line Strategy. Through this programme, NWO supports ten-year public-private partnerships that address major societal challenges. Consortia define their own research themes, provided these align with the Dutch government’s Knowledge and Innovation Agendas.

FH-EARLY – New strategies for the early diagnosis, risk stratification and co-management of familial hypercholesterolemia (Project duration: 2025 – 2028)

Familial hypercholesterolemia (FH) is the most common inherited metabolic disorder in the world with about 2.5 million Europeans affected. Individuals with FH present a high cardiovascular risk but there are different effective treatments to reduce this risk; however, these high-risk individuals are not being clinically identified. An accurate diagnosis through genetic testing confirms the disorder in only about half of the cases, in the other 50% the cause for the severe hypercholesterolemia remains unknown, preventing the best management of their disorder. FH-EARLY will enable new strategies for earlier diagnosis and co-management of familial hypercholesterolemia. This will be facilitated by well-defined data flows, identifying new mechanisms through analyzing big sets of biomolecular data (multiomics), explainable AI modelling, and co-creation with families with FH and caregivers.

LUMC and CWI are responsible for the work packages in which their multi-modal explainable AI techniques will be tailored and applied to the FH use case.

The consortium consists of the following partners (in alphabetical order): Assistance Publique – Paris University Hospitals (AP-HP) – France, Association for Research and Development of the Faculty of Medicine – CCUL (AIDFM) – Portugal, Centrum Wiskunde & Informatica – NWO Institute for Mathematics and Computer Science (CWI) – Netherlands, Centre for Innovation in Medicine (INOMED) – Romania, Ege University (EU) – Turkey, FH Europe Foundation (FHEF) – Netherlands, Hacettepe University (HU) – Turkey, National Institute of Health Dr. Ricardo Jorge (INSA) – Portugal, Leiden University Medical Center (LUMC) – Netherlands, Masaryk University (MU) – Czech Republic, Moncyte Health (MON) – Finland, Madrid Health Service (SERMAS) – Spain, Sorbonne University (SU) – France, University of Helsinki (UH) – Finland, Saint Joseph University (USJ) – Lebanon.

Explainable AI for Health Equity: Transforming Cancer Care and Beyond in Aotearoa (Project duration: 2025 – 2028)

This project focuses on two key areas:

1. Explainable AI in medical applications – with an emphasis on genetic programming techniques.
2. Tailoring and externally validating the novel BRIGHT approach for insightful internal radiation treatment planning.

The initiative is a collaborative effort uniting computational scientists, (radiation) oncologists, medical physicists, radiation therapists, and the broader AI research community. By fostering an ecosystem of cross-disciplinary exchange through workshops and joint research, the project promotes the adoption of explainable and ethical AI practices in healthcare – strengthening both cancer care and the broader AI landscape in Aotearoa.

PIs involved in this work are Dr. Andrew Lensen (Victoria University of Wellington), Prof.dr. Peter A.N. Bosman (CWI), and Prof. dr. Tanja Alderliesten (LUMC).

Further, this research will be performed in close collaboration with Wellington Regional Hospital.

DIRECT-DCIS – Dynamic Integrative Risk forecasting to Conquer overTreatment of Ductal Carcinoma In Situ (Project duration: 2024 – 2032)

LUMC and CWI are responsible for the work package in which novel eXplainable Dynamic Prediction Modeling (XDPM) Artificial Intelligence (AI) techniques will be developed. The focus is on the development and validation of an explainable AI approach for individualized risk prognosis for women with a precancerous stage of breast cancer (ductal carcinoma in situ: DCIS).

The vision is that DCIS treatment will switch from a “one size fits all” treatment towards a personalized approach, based on the predicted specific risk and preferences of each individual patient. Insightfully informed low risk patients can go for a watchful-waiting approach, thereby omitting surgery, and keeping quality of life, as well as saving unnecessary healthcare costs. Medium-risk patients can opt for surgery, while high-risk patients can opt for surgery followed by radiotherapy. This approach will lead to both personalized and affordable healthcare.

Further collaboration within this work package is mainly with the NKI-AVL, Radboud UMC, and TU Delft as well as industry partners DEARhealth and IQVIA – CTcue.

The consortium consists of the following partners (in alphabetical order): BOOG Study Center (Dutch Breast Cancer Research Group), DEARhealth, Delft University of Technology (TU Delft), Dutch Breast Cancer Association (BVN), Erasmus University Rotterdam (EUR), IQVIA, Leiden University Medical Center (LUMC), Netherlands Cancer Institute (NKI), Netherlands Comprehensive Cancer Organization (IKNL), Netherlands Institute for Health Services Research (NIVEL), NWO Institute CWI: Centrum Wiskunde & Informatica (CWI), PALGA Foundation (Pathologisch-Anatomisch Landelijk Geautomatiseerd Archief), Radboud University Medical Center (Radboudumc), RIVM (National Institute for Public Health and the Environment) – Center for Population Screening, ScreenPoint Medical, University Medical Center Utrecht (UMCU), and University of Twente (UT).

Explainable Artificial Intelligence (Project duration: 2022 – 2027)

The focus of this project is on the development and clinical validation of explainable AI techniques for applications in medicine. For this innovation an ecosystem of close collaboration between experts with different backgrounds is needed. We aim to develop and tailor the application of such techniques for decision support in palliative oncological care and gynaecological cancer care. The ultimate goal of this project is to develop a general methodology together with guidelines so to that it can become available in an easy-to-be-tailored-to-other applications format. For this, the paraganglioma use case will be used as a test case.

This research is a close collaboration between LUMC, CWI, and Amsterdam UMC. This research is funded by the Stichting Gieskes-Strijbis Fonds.

DAEDALUS – Distributed and Automated Evolutionary Deep Architecture Learning with Unprecedented Scalability (Project duration: 2021 –2026)

To use deep learning, practitioners need to first decide what neural network architecture to use. This can be a non-trivial task, especially for new applications. Another form of AI, evolutionary algorithms, has shown much promise here, auto-designing architectures that outperform expert-designed ones, but at substantial computational overhead. In this project, we aim to improve the scalability of such neuro-evolution. We also aim to develop solutions for when data can be shared as well as when only information on learning can be shared. Finally, we focus on utilization through two applications in radiation oncology: auto-contouring of medical images and predicting dose distributions for brachytherapy cancer treatment planning.

This project involves a close collaboration with two commercial parties (Elekta and ORTEC Logiqcare) and internationally renowned experts in the field of design of evolutionary algorithms for deep neural architecture learning, analyzing and optimizing landscapes underlying classical neural networks, evolutionary algorithms, as well as experts in brachytherapy to develop and display the potential power of evolutionary machine learning to innovate brachytherapy treatment planning.

This research project (with project number 18373) is funded via the research programme Open Technology Programme by the Dutch Research Council (NWO). Part of the funding is provided by Elekta and ORTEC logiqcare.

Fast, accurate, and insightful brachytherapy treatment planning for cervical cancer through artificial intelligence (Project duration: 2020 –2026)

Current software for brachytherapy treatment planning requires much inefficient and not insightful human interaction, best described as improving a single treatment plan through stepwise trial-and-error. Moreover, current automation targets objectives that are not in-line with clinical evaluation criteria. This makes treatment planning highly time-consuming, very complicated, and increases the risk of treating patients with sub-optimal trade-offs between coverage of the tumor and sparing of the surrounding tissues.

We have developed a novel AI-based approach, called BRIGHT, to automated planning for brachytherapy in a prior project (collaboration between CWI and Amsterdam UMC, funded by NWO and Elekta). Different from currently available software, the underlying unique and powerful optimization engine can directly effectively target clinical evaluation criteria. The approach is furthermore more insightful, because instead of a single treatment plan, a palette of treatment plans, representing trade-offs between target coverage and organ sparing, is automatically computed. For prostate high-dose-rate brachytherapy this approach was shown to result in better treatment plans in a fraction of the time compared to current clinical practice.

For the generalization and fundamental expansion of BRIGHT to cervical cancer brachytherapy treatment, in this project we are developing and validating novel, user-friendly, and fast brachytherapy treatment planning software. The clinical translation potential will be established and demonstrated by nation-wide validation studies.

This research is a close collaboration between LUMC, CWI, and Amsterdam UMC. Further, Catharina Hospital Eindhoven, Erasmus MC Cancer Institute, UMC Groningen, Maastro Clinic, The Netherlands Cancer Institute, Radboud UMC, and UMC Utrecht are involved in the nation-wide studies.

This research is funded by the Dutch Cancer Society (KWF Kankerbestrijding: Project N. 12183) and Elekta.

EXAMINE– Evolutionary eXplainable Artificial Medical INtelligence Engine (Project duration: 2020 –2026)

Machine learning (ML), especially in the form of deep learning, has shown to be capable of impressive results in many fields of science and society. Nevertheless, in most cases, learned models are still incomprehensible black boxes for humans. Especially for disciplines such as medicine, the inexplicability of ML is a bottleneck for its widespread adoption, because medical experts want to understand why a certain prediction is made.

In this project, we therefore focus on developing new forms of AI that provide models that can be insightfully inspected and understood.

We will deploy the resulting AI method, called EXAMINE (Evolutionary eXplainable Artificial Medical INtelligence Engine), on a unique and recent real-world clinical dataset of gynaecological cancer patients.

This research is a close collaboration between LUMC and CWI.  Further, the Poznan University of Technology is involved.

This research is part of the research programme Open Competition Domain Science-KLEIN with project number OCENW.KLEIN.111, which is financed by the Dutch Research Council (NWO).

TRUST-AI – Transparent, Reliable, and Unbiased Smart Tool for AI (Project duration: 2020 –2025)

LUMC and CWI are responsible for the health care use case of this large EU project. The focus is on the development and validation of transparent, reliable, and unbiased AI for improved clinical decision making for patients with paraganglioma.

Clinical decision making is extremely challenging for these typically slow-growing tumors that might develop progressively and therefore require specific treatment (i.e., surgery or radiation treatment) at some point in time. We are investigating if it is possible to predict the moment of onset of complaints. This would make it possible to patient-specifically adapt the follow-up with advantages for both patients and caretakers. Further, a timely chosen moment for treatment (i.e., prior to the onset of (irreversible complaints) will greatly improve the quality of life of the patients.

Further collaborations within this EU project are mainly with the University of Tartu (regarding counterfactuals) and industry partner Tazi (regarding user interface design).

This research is funded by the European Commission within the HORIZON Programme (TRUST AI Project, Contract No: 952060).

Multi-Objective Deformable Image Registration (MODIR) – An Innovative Synergy of Multi-Objective Optimization, Machine Learning, and Biomechanical Modeling for the Registration of Medical Images with Content Mismatch and Large Deformations (Project duration: 2018 –2024)

By taking a multi-objective perspective on deformable image registration, we aim to remove the necessity to ad hoc fine-tune parameters, paving the road toward broad use of deformable image registration in clinical practice. In this project we further aim to solve image registration problems that are currently hardly solvable (i.e., cope with large deformations, including sliding tissue and content mismatches between image acquisitions).

LUMC and CWI collaborate closely with two commercial parties (Elekta and Xomnia) as well as end-users of the software (e.g., medical experts) to establish efficient and user-friendly ways to present, select, and use final deformable image registration outcomes. The collaboration consists of the development and validation of a novel AI-based multi-objective approaches to deformable image registration.

This research also involves collaboration with the Amsterdam UMC, location AMC.

This research is part of the research programme Open Technology Programme with project number 15586, which is financed by the Dutch Research Council (NWO), Elekta, and Xomnia. Further, the work is co-funded by the public-private partnership allowance for top consortia for knowledge and innovation (TKIs) from the Ministry of Economic Affairs.

FEDMix – Fusible Evolutionary Deep Neural Network Mixture Learning from Distributed Data for Robust Medical Image Analysis (Project duration: 2018 –2022)

Automated medical image analysis has the potential to truly innovate clinical practice by offering solutions to routine, yet key tasks, such as segmentation (i.e., delineating organs). Especially with recent advances in machine learning, in particular in deep neural networks that have led to an explosive growth of successful medical image analysis studies reported in academic literature, the time appears right for such innovations to find widespread real-world uptake. Yet, labor-intensive manual performance of these tasks is still often daily clinical practice.

In this research project, we aim to overcome a key obstacle in moving toward widespread clinical uptake of computationally intelligent medical image analysis techniques: observer variation in the definition of a ground truth.

The motivation behind this research project is to realize fundamental and clinically transferrable (in radiation oncology) innovation, validated in the real-world clinical setting of radiation treatment, by uniting and cross-fertilizing, in a novel manner, expertise in four different research fields: evolutionary algorithms (CWI/LUMC), deep (neural network) learning (eScience Center), medical image analysis (LUMC/eScience Center), Efficient Computing (eScience Center), and radiation oncology (LUMC/Amsterdam UMC, location AMC).

This research is part of the research programme Commit2Data with project number 628.011.012, which is funded by the Dutch Research Council (NWO).
