Longitude intra-subject registration with pathology: Data Available

A new collection of synthetic data for the development and evaluation of registration methods has been released.

This collection of synthetic data is intended for the development and evaluation of methods for intra-subject registration in the presence of changing pathologies.

Specifically, we developed this data to evaluate our Geometric Metamorphosis registration method [2] for the quantification of tumor progression (e.g., estimating its infiltrating and displacing components). This method is also being applied to the quantification and prediction of chronic blood perfusion changes after Traumatic Brain Injuries.

In this data collection three variables are explored:

  1. Tumor location: near edge of brain versus in the center of brain.
  2. Tumor size: small versus large.
  3. Tumor type: highly infiltrative, mix of infiltrative and displacive, and highly displacive.

Data:

The image data were generated using the TumorSim 1.2 software developed at the University of Utah by Marcel Prastawa [1] and initiated using a healthy MRI study from the BrainWeb database.

This data generation effort was supported in-part by:

  1. NIH/NIBIB grant “National Alliance of Medical Image Computing” (NA-MIC, PI: Kikinis, 1U54EB005149)
  2. NIH/NCI grant “Image Registration for Ultrasound-Based Neurosurgical Navigation” (TubeTK, PI: Wells, Aylward, 1R01CA138419)
  3. NIH/NCI grant “A Needle Guidance System for Hepatic Tumor Ablation that Fuses Real-Time Ultrasound” (InnerOptic, PI: Razzaque, R1R44CA143234-02A1)
