+Elaine, Eric, Greg, Tom G; Kristen, Darrell, Phil, Bhinnata, Andi
+
+TomG and Phil discuss Quest3 improvements over earlier versions. Zach is in Kansas now for the Phenix meeting.
+
 [https://www.rsna.org/annual-meeting Radiological Society of North America meeting] is Nov 26-30. After our previous meeting (Oct 26), Elaine sent Phil and Meghan e-mail about current ChimeraX DICOM features and the test data we've been using. Zach would be the one to advise about showing this stuff in VR specifically, but he's currently out of town presenting at another meeting.
+
+Phil: I've been testing the latest DICOM tools in VR, some issues:
+
+(1) Noticed that windowing/leveling with VR controller isn't updating in histogram in VR, only on the monitor. TomG: yes it doesn't know when to update the panel in VR; doing it continually may be too computationally expensive and cause flicker. Phil: may be less important with pass-thru, can view monitor.  TomG: it wouldn't be hard to change the code for more panel updates and see how it affects performance. Eric: maybe there could be a button assignment to toggle panel updates.  
+
+(2) thresholds were not saved in sessions. TomG: that would be very surprising. They should be saved. What version are you using? Elaine: maybe Zach has code that recognizes DICOM and automatically resets thresholds. Phil: I can explicitly set them with the "volume" command. I can find out the values with "volume settings" TomG: manual adjustment should log the corresponding command. You can also use "buttonpanel" to make a custom GUI with buttons that run commands.
+
+Phil: the RIDER lung data with the tumor shows up nicely in VR.  With the right thresholds, it seems to even have an outline.  Elaine: maybe there is a slightly denser capsule around the tumor.
+
+When Zach is back (next week) maybe he can advise in more detail about showing the DICOM Segmentations tool in VR.  Elaine: you can open the DICOM that already has segmentations, and edit them.  Erase bits, add bits, etc.
+
+Phil, re NIH3D: how to visualize struts, discussed previously with Eric.  Halfbond coloring looks better than a separate color, let's use halfbond in the presets.
