Slicer Sound control not working

[may1968]

Hi Andrea,

Greetings - I have been getting help from Mark Asselin for tracking ultrasound. I'm a urologist from Cape Town, South Africa.

I wonder if you could advice me on the Slicer sound control. I have followed the instructions on the github site.

1. The BreachWarningScene.mrb on github seems an empty scene. Nothing on data and no needle or cylinder like seen as on example here: https://github.com/SlicerIGT/SlicerSoundControl
   I'm using slicer 4.10.2 and Purr Data 2.10.0

2. The only .mrb I could find is here: https://github.com/SlicerIGT/SlicerSoundControl/tree/master/SoundNav/Resources

3. The log on purr-data has the following:

error: <!DOCTYPE: no such object
[2] error: v=4": no such object
error: user-name&gt: no such object
error: /&lt: no such object
error: repo-name&gt: no such object
error: /blob/show": no such object
error: ">: no such object
error: v=4": no such object
error: ">: no such object
error: v=4": no such object

etc etc.

thanks
John

Hi Andrea,
I found this in the Slicer error log. It appears as if the .mrb file is corrupted. This error does not occur with other scenes I have.

Unpacking bundle "C:/Users/User/Documents/ARUCO/sound NAV/BreachWarningScene.mrb" to "C:/Users/User/AppData/Local/Temp/__BundleLoadTemp2020-04-24_15+34+07.635"

Info: In D:\D\S\Slicer-4102\Libs\MRML\Logic\vtkArchive.cxx, line 35
vtkArchive Error: Unzip: Cannot open archive file Error

It seems that you have downloaded the file incorrectly. You need to download the file by clicking "Download" button on the file's github page (the download link is this).

Hi Andras,Thanks so much - basic error. I have it working now.2 quick questions:1) Using SoundNav with a tracked ultrasound. How would I fix a target (say a sphere model) in the 3d workspace related to a point on the sonar image -I tried putting a fiducial there, but did not work. I moved the sphere/cylinder transform onto the tracked image transform, but is moves with the image which is no good. Any ideas of how to achieve this?2) Your newly released ultrasound volume reconstruction is very user friendly and I has it up and running quickly. The youtube video omits mention of turning on vol rendering, also the volume rendering presets don't give a good appreciation of soft tissue in ultrasound. The you tube used bone in fluid, but in vivo does not have the same interface differences to render clearly. Any advice? Are there specific vol rendering presets for ultrasound - or other tricks?thanksjohn lazarusCape Town  On Friday, April 24, 2020, 03:44:43 PM GMT+2, Andras Lasso <[email protected]> wrote: It seems that you have downloaded the file incorrectly.

What you say is interesting, because by default fiducial points created in Slicer are positioned relative to the viewer coordinate system (called "RAS" in code, or "Scene" in the transform hierarchy). If points move with your image, then they are transformed together with the image. Are you sure you didn't put your markups on the same transform node that the image is on?
The YouTube video skips a few issues that we plan to fix in the near future. E.g. the reset button does not clear the volume immediately.
For volume rendering presets, the MR-Default preset works fine for ultrasound. You can change the color and transparency a little bit in the advanced display section to improve the appearance.
