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.

Individual impedance-based radio-frequency heating temperature field prediction method and system

The present application relates to computer-based preoperative planning technology, and discloses a preoperative planning method for multimodal ablation treatment and apparatus thereof, which can automatically provide objective, scientific, and quantitative multimodal ablation planning information. In this method, acquiring parameters of an volume to be ablated; calculating property changes of the tissue caused by performing freezing on the volume according to the parameters of the volume to be ablated, and acquiring a first planning data required for the property changes of the tissue to satisfy a first predetermined condition; further calculating property changes of the tissue caused by performing heating on the volume to acquire a second planning data required for the property changes of the tissue to satisfy a second predetermined condition based on the properties satisfying the first predetermined condition; outputting the first planning data and the second planning data.

Preoperative planning method for multimodal ablation treatment and apparatus thereof

An apparatus used for increasing the level of CD4T cells in a mammal. The mammal has a cancerous tissue. The apparatus comprises a cold treatment unit and a heat treatment unit. The cold treatment unit is used for cooling the cancerous tissue. The heat treatment unit is used for heating the cancerous tissue. A method for increasing the level of CD4T cells in the body of a cancer patient, comprising steps for cold treatment of the cancerous tissue and for heat treatment of the cancerous tissue.

System and method for tumor treatment

Provided are a tumour immunogen, a preparation method therefore, and an application. After localised sequential cooling-heating treatment is performed on tumour tissue and/or cells, the tumour tissue and/or cells release a large amount of tumour immunogen heat shock protein 70. The obtained tumour immunogen can activate the body's tumour immune system, to convert immunosuppressive cells into mature dendritic cells, thereby increasing immunogen presentation, and activating tumour immunity.
