Embodiment Construction
[0024] The present invention will be further described below in conjunction with accompanying drawing:
[0025] The present invention studies the problem that ultrasound cannot obtain images of blood vessels under bones, and designs a set of blood vessel visualization devices and methods based on catheter paths to expand ultrasound imaging areas.
[0026] Vascular minimally invasive interventional surgery can effectively treat diseases under minimally invasive conditions. Three-dimensional Doppler ultrasound is a safe and real-time intraoperative imaging method to obtain vascular morphology, which can accurately and quickly provide intraoperative vascular images to guide the catheter to the target position. However, ultrasound cannot penetrate strong reflectors such as bones to obtain images of blood vessels beneath them for catheter navigation. In the present invention, the catheter path is used to replace the spatial position and direction of the blood vessel in the ultraso...
