Biplanar ultrasound image planning method and apparatus

A biplanar ultrasound image planning method, which is a biplanar ultrasound image planning method captured by an ultrasonic probe, characterized in that, and comprising the following steps:

• calibrating a position relationship between a first ultrasonic probe and a cross-sectional image to obtain a first conversion matrix, the first conversion matrix being a matrix converted from a coordinate system of the cross-sectional image to a coordinate system of the first ultrasonic probe;
• calibrating a position relationship between the first ultrasonic probe and a sagittal image to obtain a second conversion matrix, the second conversion matrix being a matrix converted from a coordinate system of the sagittal image to a coordinate system of the first ultrasonic probe;
• calculating a third conversion matrix and/or a fourth conversion matrix based on the first conversion matrix and the second conversion matrix, the third conversion matrix being a matrix converted from the coordinate system of the cross-sectional image to the coordinate system of the sagittal image, and the fourth matrix being a matrix converted from the coordinate system of the sagittal image to the coordinate system of the cross-sectional image;
• and
• displaying a target position displayed in any of the coordinate system of the cross-sectional image and the coordinate system of the sagittal image in the other coordinate system in a follow-up manner.
