Phased-array thermal therapy machine and control method thereof

Abstract

The invention provides a phased-array thermal therapy machine and a control method thereof. The phased-array thermal therapy machine comprises a controller and a plurality of electrode rings, whereinthe electrode rings are coaxially arranged at intervals, each electrode ring comprises a ring body and a plurality of radio frequency electrodes which are arranged on the inner surface of the ring body at intervals, and the controller is electrically connected with the radio frequency electrodes separately and is suitable for controlling signal parameters of radio frequency signals transmitted bythe radio frequency electrodes to adjust the thermal therapy position. According to the technical scheme, the thermal therapy position is focused by adjusting the signal parameters of the radio frequency signals transmitted by the radio frequency electrodes, and the accuracy of the thermal therapy position and the comfort in the thermal therapy process are improved.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence, in particular to a phased array thermotherapy machine and a control method thereof. Background technique [0002] Tumor hyperthermia refers to the use of physical methods such as heating to raise the temperature of tumor tissue to the effective treatment temperature, and utilize the difference in the heat resistance of normal tissue and tumor cells to achieve the treatment of killing tumor cells without damaging normal tissues Purpose. [0003] Among them, radiofrequency hyperthermia is a common method in tumor hyperthermia. At present, radiofrequency hyperthermia often uses the following two methods to heat the target position: one is to use a ring coil for heating, and the patient is located in the ring coil during hyperthermia. The coil is fed with an alternating current, and the ring coil generates a radio frequency alternating magnetic field, which heats the cell tissue thro...

[0003] Among them, radiofrequency hyperthermia is a common method in tumor hyperthermia. At present, radiofrequency hyperthermia often uses the following two methods to heat the target position: one is to use a ring coil for heating, and the patient is located in the ring coil during hyperthermia. The coil is fed with an alternating current, and the ring coil generates a radio-frequency alternating magnetic field, which heats the cell tissue through the alternating magnetic field. This method will not overheat and damage the subcutaneous fat, but the heating area is large, and it is easy to damage other cell tissues.

The other is to use parallel electrode plates for heating, set parallel electrode plates on the body surface of the area to be heated, apply radio frequency voltage to the parallel electrode plates, and generate Joule heat between the cells and tissues through the current conducted between the parallel electrode plates. Heating, but this method will heat the subcutaneous fat at the same time, which is easy to damage the skin, etc., and the electrode plate needs to be close to the body surface, so the operation is complicated
