Researcher writing open-source code for ocular MRI analysis at Leiden UMC

Open Science and Data

We embrace the Open Science movement to make research more transparent and share data as much as possible. This means our projects are reviewed and validated by our peers and our output, whether it is software, methods or data, is made accessible to the benefit of other scientists, healthcare professionals and patients.

Software

See the software overview page for a complete list of our software, including main contributors, requirements and related publications.

  • Visisipy is a Python library for optical simulations of the eye. It provides an easy-to-use interface to define and build eye models, and to perform common ophthalmic analyses on these models. A simple version of Visisipy can even run from your browser.

  • pyROT is a Python library that complements RayOcular, the eye-specific module of RayStation. For example, it provides methods to build patient-specific eye models for radiotherapy planning.

  • ZOSPy is our open-source platform to perform optical simulations in OpticStudio and share them with other scientists through Jupyter notebooks.

  • PAROS is a tool to calculate the magnification of fundus photographs based on the optical characteristics of the patient’s eye, as described in Correction Method for Optical Scaling of Fundoscopy Images.

  • OPT Tumour Models generates polynomial tumor models for ocular proton therapy planning from 3D tumor delineations.

We are also active users of, and contributors to, third-party open-source tools, such as Optiland, the open-source ray-tracing engine used by Visisipy.

Methods

Quantitative MRI

Ray tracing

MRI protocols

  • MRI protocol for intraocular pathology, our standard MRI protocol to visualize the eye and internal structures. It contains high-resolution anatomical sequences to assess the lesion’s extent and origin, as well as functional sequences that can aid in the differential diagnosis.
  • Other protocols will be added at a later stage

Other methods

  • An overview of our publications of which the methods/scripts are freely available.

Publications

Currently 98% of our publications are available free of charge:
88% as Open Access paper through the publisher's website and 10% through online repositories
