OA mode data

[Junha0Zhang]

Hello! I'm trying to get access to the image data in OA mode after connecting the laser. However, I can only see a regular ultrasound image and a single scan line data (please see the figure below). What should I do to get the complete image data? The OA mode seems very new and I didn't many instructions online, so your help would be much appreciated.

correct, we only display the center line of data that is collected, you will need to enable the raw data buffering and download it during the image/cine capture. Note the way our OA feature works is to send a "pulse" (ie. trigger the laser), and then receive 1 channel on that element, so moving across the probe, we end up with 192 individual pulses + channels that are collected and can be reconstructed. Note there is about 6 microsecond delay from the trigger output to reception of the signal in case that impacts how the laser is triggered.

Thank you! Now I have access to the complete image data. However, it seems that the image is not scan-converted. Is there any script for scan conversion?

@Junha0Zhang I've used this library to do scan conversion: https://fast.eriksmistad.no/python-tutorial-ultrasound.html.

@clariusk It would be nice if there we had a Clarius function to do this since I've had a bit of hard time getting the raw data to look like the Clarius fan shape output but maybe that's proprietary.

yes, we don't publish our scan conversion as it is proprietary to our system, thanks
