Four-dimensional is real-time three-dimensional, and four-dimensional color Doppler ultrasound obtains three-dimensional image information through ultrasonic imaging by mechanical or electronic methods. This method is easy to operate and apply. Cross-sectional imaging is often used to examine uterine and ovarian diseases, and volume probe is more convenient to observe fetal morphology.
Ultrasonic volume probe is a kind of ultrasonic imaging equipment, which is mainly used for ultrasonic volume imaging. Multi-plane imaging can be realized to reduce artifacts caused by partial volume effect. It is of great help to improve the accuracy and accuracy of disease diagnosis.
