3D Ultrasound Data
About 3D Ultrasound
The software can acquire new interoperative 3D ultrasound data sets. It scans the volume of the patient’s head and reconstructs the live ultrasound images to a 3D data set and displays it superimposed on the preoperative MR data. The new data set can be used for navigation purposes.
- To acquire 3D ultrasound, start a scan in scan mode.
- Afterwards, you can compare the ultrasound to the original MR/CT data, or view the superimposed ultrasound over an MR/CT.
Tips for Acquiring 3D Ultrasound Data
- Clean up the cavity to eliminate blood, especially coagulated blood
- Fill cavity with saline and wait to let bubbles settle
- Move the probe in one long, slow, steady sweep (approximately 10 seconds)
- Perform the scan by moving the probe in the one anatomical direction (e.g., sagittal) for best reconstruction quality
- The tracking array should face the camera as much as possible
- Do not move the probe over the same area twice
