The invention discloses a local
ablation method for
liver cancer. The local
ablation method comprises the following steps: carrying out modular partition including the liver, the tumor focus, the
blood vessel and the tissue around the liver in sequence on the preoperative image after registration, and carrying out puncture path planning and puncture thermal field planning; carrying out multi-
modal image registration on the preoperative image and an intra-operative image, outputting the tumor focus of the preoperative image, and displaying the tumor focus on the intra-operative image in a fusion manner; and carrying out multi-
modal image registration on the preoperative image and a postoperative image, outputting the tumor focus in the preoperative image, and displaying the tumor focus in the preoperative image on the postoperative image in a fusion manner, wherein the preoperative image and the postoperative image respectively comprise the CT image and / or MR image of the
time sequence, and the intra-operative image comprises the CT image. According to the method, the
image registration step is added in
preoperative planning, the intra-operative locating and postoperative assessment, thus the scientific planning for the tumor
thermal ablation before the operation, the visual and effective information display in treatment during the operation, and the scientific assessment for the curative effects and the
treatment experience feedback after the operation are realized, so that the
preoperative planning is guided.
