Project Title: Generation of a hybrid MR-Spectroscopic (MRS) dataset under 3DSlicer

Key Investigators

  • SPL: Jan Egger, Isaiah Norton, Tina Kapur, Alexandra Golby
  • UKGM: Daniel Hořínek, Jens Sommer, Christopher Nimsky
  • ETHZ: Bjoern Menze
  • IKEM: Antonín Škoch

Objective

Generating a hybrid MR-Spectroscopic (MRS) dataset under 3DSlicer that can be used for fusion with the anatomic dataset under iPlan of BrainLAB in AMIGO. A hybrid MR-Spectroscopic dataset can for example be used for biopsy targeting in brain tumors. Besides, the metabolic concentrations and ratios can help to diagnose lesions.

Approach, Plan

Try to process MRS data with the MRSI module from Bjoern Menze developed at a previous project week. The module interfaces SIVIC, which is an open-source standards-based software framework and application suite for processing and visualization of DICOM MR Spectroscopy data.

Progress

Loaded/integrated processed chemical shift-MRS data from Uni. Marburg into Slicer4.

Pending:

- updating SIVIC-Slicer module to latest revision of SIVIC

- port module to Slicer4 -

Delivery Mechanism

Towards a 3DSlicer module...
