Project Description
Objective
- Continue work on open-source system for tracked MRI-TRUS fusion for prostate IGT interventions (targeted biopsy primarily)
Approach, Plan
- discuss optimal Plus setup to address the issue of 32-bit only tracker drivers and 64-bit volume reconstruction
- command line invocation vs OpenIGTLink communication for Plus sequence operations
- discuss the use of slicelet as user interface
Progress
Improvements and next steps discussed:
- develop slicelet to simplify the workflow, reuse the components developed in the slicelet base class developed by Laszlo
- chain 32-bit Plus to 64-bit to work around the limitation of 32-but drivers for Ascension (thanks to Adam for preparing Plus config files to support this setup, latencies need to be tested)
- acquisition optimizations: use scout + real-time volume reconstruction, send transform to PlusServer to support different depth settings without the need to restart it
First use of EM-tracked freehand TRUS during prostate biopsy attempted at BWH on June 9; identified issues that need to be discussed with the Plus team:
- disconnect of framegrabber freezes everything
- sensor out of the box is not reported as a warning
- need to record sensor quality
- error messages about missing frames from framegrabber
- sometime Slicer/Plus get into a state where it is not possible to establish OpenIGTLink connection; the only solution was to restart the PC!
- need to consider separate Plus instances for tracker data collection (32 bit) and framegrabber data (64bit for volume reconstruction)
