On-site Genentech Hall N436A

= Agenda =

* Elaine presents DICOM software review
* ChimeraX 1.4 release schedule
* NIAID contract
* Review Action Items listed below

= Discussion Notes =

* Computer security audit
  - Scooter had 10 half-hour meetings in past week, not much progress.
  - Scooter working on IS3 documentation on web site.
  - TomF concerned that expiring SSL certificates won't be renewed by UCSF IT if some security issues are not fixed such as Opal struts component.

* Demonstration of DICOM viewers by Elaine
  - Showed extensive ChimeraX DICOM written 2 years ago including example data sets.
  - Will show Slicer and Horos.
  - Both Slicer and Horos remember data sets you have opened in a database.
  - Showed lung CT scans from RIDER dataset with cancer tumor segmentations found by different segmentation algorithms.
  - Current Slicer is much different than 2019 version that Elaine used before.
  - Slicer does not correctly show Jason Rubenstein's 4D echocardiogram.  Appears to show 1000 2d frames as 1000 time points instead of 25 time points with 40 slices per time.
  - Slicer shows 3 orthogonal views.  Can also show volumetric 3D rendering.
  - Showed ChimeraX on same lung cancer segmentation data set.
  - Showed Horos which has the same problem as Slicer with Jason Rubenstein data.
  - Horos has hundreds of options for rendering and other preferences.
  - Significant weakness of ChimeraX with DICOM is it does not indicate modality (CT scan, MRI scan, segmentation, ...) unless that is in the name of the "study".
