Project Description

Slicer-Liver is an advanced 3D Slicer extension developed for liver therapy planning. The extension currently offers essential features for liver resection planning and accurate computation of vascular territories. As part of an ongoing project, our aim is to further enhance the existing functionalities and introduce new tools for volumetry computation. Our objective is to provide a comprehensive and user-friendly solution for liver therapy planning within the Slicer platform.


  1. Advanced manipulation of deformable surfaces for resection planning. Our current solution for resection planning involves the deformation of Bezier surfaces in a 4x4 grid implemented by means of Slicer Markups (https://slicer.readthedocs.io/en/latest/user_guide/modules/markups.html). We are planning to include advanced features such as coloring and grouping of markups for a more effective manipulation.
  2. Volumetry computation. Planning of liver therapies largely relies on a volumetry analysis derived from the therapy plan. We are planning to include versatile tools for volume computations.
  3. Release of Slicer-Liver 1.0. As Slicer-Liver is becoming an feature rich extension, we aim to release the latest developments achieved during this and the last Project Week in the extension manager (currently, the version released in the Extension Manager does not contain the latest advances).

Approach and Plan

  1. Discussion and find a strategy to improve our Markups-based resections interaction (Custom C++ markups vs. Python logic)
  2. Implementation of the new features (new markups interaction and volumetric computation tools).
  3. Testing of the new features and release of the new extension.

Progress and Next Steps

  1. Thanks to changes made by Sara Rolfe in the markup module (Seattle Children’s Research Institute USA) we are now able to modify the interaction of Markups-based resections.
  2. Integrated a new set of volumetric computation tools using the region growing method
