  • Vector field analysis plugin

  • Expansion deformation. Deformed image overlaid with Jacobian image with vector field visualization.

Key Investigators

  • Nadya Shusharina, Massachusetts General Hospital
  • Greg Sharp, Massachusetts General Hospital

Project Description

Objective

  • To create a tool for validation of deformable image registration

Approach, Plan

  • We plan to introduce a scripted module that will take a deformation vector field as an input and calculate the determinant of Jacobian matrix. The image of Jacobian will be shown as an output. Statistics of Jacobian image will be calculated and shown in the module output. The interface of the module will be in Python and computations are in C++. The module will be integrated with Plastimatch and SlicerRT.

Progress

  • The module is created. Determinant of Jacobian matrix is calculated and shown as an image. Minimum and maximun values of Jacobian are shown in output area. Some bugs to be fixed.
