Embodiment 1
[0045] See Figure 1 to Figure 3 , the present invention specifically comprises the following steps:
[0046] a. Accurate B-ultrasound image scanning of the tumor tissue through the positioning B-ultrasound probe installed in the central hole directly above the treatment transducer in the HIFU treatment system;
[0047] b. For a group of B-ultrasound two-dimensional images collected by the HIFU treatment system, manually outline the tumor area and sensitive area on the background of the two-dimensional B-ultrasound image;
[0048] c. The HIFU treatment system constructs a three-dimensional contour body after outlining. According to a series of B-ultrasound images scanned precisely and the depth of the coronal plane, linear difference calculation is performed to obtain image information of the coronal plane and generate visualized coronal planes of different depths. face image;
[0049] d. According to the three-dimensional contour and cut plane, select the angle, plan the cu...
