Abstract: Disclosed are a fast planning system and method applicable to ablation therapy. The system comprises an input device, a calculation device and an output device, the calculation device obtains a boundary of the tumor and an actual position of an ablation probe relative to a tumor through the input device, the quantitative relationship between the ablation range and the ablation parameters of the ablation probe, and maximum ablation range parameters of the ablation probe. The system obtains the ablation parameters of the ablation probe by means of the calculation device based on the obtained information, outputs the ablation parameters by means of the output device, and obtains a revised planning suggestion.

Abstract: The present application relates to the field of biomedical engineering. Disclosed are an individual impedance-based radio-frequency heating temperature field prediction method and system which greatly improve the rate and accuracy of temperature distribution prediction. The method of the present application comprises: creating a first region; obtaining a position of an ablation needle, and with the ablation needle as a center, creating a second region in the first region; keeping the electrical conductivity within the second region constant, and adjusting the electrical conductivity in the first region such that impedance between the ablation needle and an earth pole is consistent with real individual impedance actually measured by a treatment system; performing mesh division on a combination of the first region and the second region and performing coupling computation using a radio-frequency field model and a biological heat transfer model to obtain temperature field time-space information.
