Claim 0:
1. A preoperative planning method for multimodal ablation treatment, comprising:
acquiring, by one or more processors via an input device, one or more parameters of a volume to be ablated, wherein the volume to be ablated comprises a tumor;
calculating, by the one or more processors, a freezing dosage required for effecting one or more first property changes to tissue within the volume according to both mechanical and biological effect of the freezing on the tissue within the volume and the one or more parameters of the volume to be ablated;
acquiring, by the one or more processors, a first planning data required for the one or more first property changes to the tissue within the volume to satisfy a first predetermined condition;
calculating, by the one or more processors, based on coupling of electromagnetic field and temperature field and taking into account the first property changes to the tissue within the volume after freezing and a synergy among treatment needles, a corresponding heating rate and total thermal dose required for in-situ disruption of all cells and/or microvessels within a boundary of the tumor to maximize release of tumor antigens and stimulate the body's immune response based on the principle of biological heat and mass transfer and thermal energy induced biological effect;
acquiring, by the one or more processors, a second planning data required for one or more second property changes to the tissue within the volume caused by heating of the tissue within the volume to satisfy a second predetermined condition; and
outputting, by the one or more processors, the first planning data and the second planning data.
