Muscle Segmentation problems at UCSD

These problems are the result of mostly UCSD user testing and some UCSF. The MuscleSegmentation plugin has its own wiki page and its own web page.

This is the current version of the plugin, available here: muscleSeg441b.jar. No issues have been reported yet, but area of aortic calcium is planned. Need standard HU for this.

A scrolling bug was discovered in this version that made the side-panel buttons inoperable. The display of the bottom buttons on this side panel also needed to be fixed. For evaluation, this plugin is still available here: muscleSeg441a.jar. A new version of the plugin was produced as a result of this bug.

This version of the plugin suffered from slow calculations when it came to volumes. While this is fixed, calculations are even faster in the upcoming release of MIPAV.

A list of problems found in MuscleSegmentation by UCSD using java1.5.0_13 and 12 - note that MuscleSegmentation now requires java1.6

• Statistics take longer to compute in 4.4 than 4.1 (specifically 4.1.2 and 4.1.10 had reasonable speeds) - fixed, also works well in VOI conversion
• In custom pane, VOIs can only be added in first pane (both before and after a profile has been loaded fixed, works with 1.6
• Statistics errors, need sample data - fixed, update problem solved
• GUI shows up as black on Mac, does not appear to happen with other MIPAV plugins - fixed

Features

• unit consideration - added, functional
• output per-slice - added, functional

No problems found, more testing needed:

• Overwriting VOIs, check that file has actually been written over - tested

Mipav features:

• Default VOI thickness of two, unable to change system-wide - fixed
• Alt tracing:
  • Unusual VOI flashing fixed in newer versions of MIPAV
  • Feature: VOI tracing without edge detection? working on new VOIs
