snappysonic 0.0.8

snappysonic provides an application to simulate an ultrasound probe moving over a body torso, it is intended for public engagement events"

Author: Stephen Thompson

SnappySonic can be used as an ultrasound acquisition simulator. The output from a tracking system (NDI or AruCo tags) is to select a frame of pre-recorded video to show. A suitable video of ultrasound data is included in the data directory, however the user can select a video of their choosing. The software and its use is described in the SnappySonic paper.

SnappySonic is part of the SciKit-Surgery software project, developed at the Wellcome EPSRC Centre for Interventional and Surgical Sciences, part of University College London (UCL).

SnappySonic supports Python 3.6.

pip install snappysonic
python snappysonic.py --config config.json

The config file defines the tracking parameters and image buffer, e.g.

{
 "ultrasound buffer": "data/usbuffer.mp4",
       "buffer descriptions": [
              {
               "name": "glove",
               "start frame": 0,
               "end frame": 284,
               "x0": 20, "x1": 200,
               "y0": 200, "y1": 260,
               "scan direction": "x"
              },
  ]
  ....
  "tracker config": {
              "tracker type": "aruco",
              "video source": 2,
              "debug": true,
              "capture properties": {
                      "CAP_PROP_FRAME_WIDTH": 640,
                      "CAP_PROP_FRAME_HEIGHT": 480

 }
}
