Description
technical field [0001] The invention relates to the technical field of medical instruments, in particular to a calibration device for calibrating an ultrasonic probe. Background technique [0002] Medical ultrasound imaging technology is widely used in various auxiliary treatments and auxiliary diagnosis because of its advantages of convenient use, low price, real-time imaging and percutaneous non-invasiveness. Traditional two-dimensional ultrasound images have certain limitations, such as only providing cross-sectional images of the human body. Three-dimensional ultrasound technology has become more and more widely used in recent years because it can overcome the corresponding defects. In the process of acquiring 3D ultrasound images, the calibration of the ultrasound probe is a very important step in the free-arm 3D ultrasound imaging system. [0003] The free-arm 3D ultrasound technology is to install a positioning sensor on the ultrasound probe. When the ultrasound prob...
