Mask Ultrasound Volume Vector

Support
1

Hello! I saw this video: https://www.youtube.com/watch?v=TIUWzhkdspY

Originally, the ultrasound image has some numbers and information on it, however in slicer only the ultrasound image can be seen.

Right now I have a vector volume from a stream, and I want to mask the number part.

I have been trying to accomplish that using the segmentation tool but I can’t find the right way to do it…

Once I have the area I want to work with, is there any way to save it as a mask and add it to PLUS Server for future connections? Thanks!

To blank out everything outside a segment, install SegmentEditorExtraEffects extension, then use “Mask volume” effect.

If you attach a position tracker to the ultrasound probe (can be as simple as a webcam if you don’t require high accuracy) then you can set up real-time tracked image acquisition as shown in the youtube video that you referenced above.

Mask Volume works perfectly! Thanks.

Now I can set a better ROI at the ultrasound image and then apply Mask Volume to get rid of the numbers.

So now, once I have created this “Crop Volume ROI” , is there anyway to save together with the mask, and load it again? Because I have been trying to export it as a .acsv but I don’t know how to get it back in when I reset slicer.

Also, it could be good to remove those black corners, to just display the ultrasound image. Because if I reduce the ROI I’ll be missing information.

I’ll do the real-time tracked next weekend with a tracker (I’ll have to make the ImageToProbe transformation), now I just want to make sure that I’m able to display the ultrasound image in the best way.

Thanks again for the response :slight_smile: There is a lot of documentation and tutorials, but sometimes I can’t find the proper ones for my purposes.

If you only need the mask for real-time display then it’s even simpler: create a mask image, enable thresholding in Volumes module, and set up slice viewer layers to use the mask image as background and the ultrasound image as foreground image.

Works, clean solution! Thanks :smiley:
