Title:
患部加熱システム、及び、腫瘍診断システム
Document Type and Number:
Japanese Patent JP6767030
Kind Code:
B2
Abstract:
Provided is an affected part heating system with which treatment by means of non-invasive hyperthermia and oncothermia can be performed by applying a high-frequency current to a human body, and with which it is possible to prevent destruction of cells other than malignant tumors by means of a temperature measuring device. This affected part heating system for heat treating an affected part inside a body is provided with: an electric field generating device which includes a high-frequency power source and a pair of electrodes disposed in such a way as to sandwich the affected part, and which generates an electric field in a region including a malignant tumor C by means of the application of a voltage to the pair of electrodes by the high-frequency power source; a temperature measuring device 16 including a transducer 22 which generates ultrasonic waves directed toward the affected part and receives an ultrasonic wave echo from inside the body, and a temperature calculating circuit 18 which calculates temperature information relating to the inside of a living body on the basis of the echo received by the transducer 22; and a control device which, on the basis of the temperature information measured by the temperature measuring device, controls the voltage applied by the high-frequency power source of the electric field generating device in such a way that the affected part reaches a prescribed temperature.
