Embodiment Construction

[0093] Devices and measurement methods according to embodiments of the present invention will be described below in conjunction with related drawings.

[0094] Figure 4A and Figure 4B It is a device schematic diagram of HIFU heating and temperature measuring equipment according to an embodiment of the present invention.

[0095] A practical external focused ultrasound therapy machine generally consists of the following parts:

[0096] A. High-energy focused ultrasonic source and drive circuit - used to generate high-energy focused ultrasonic.

[0097] B. Positioning system - used to find the patient treatment target and move it to the focal point of the ultrasound transducer. It includes a medical imaging system (mostly a B-ultrasound machine), a patient-carrying device (such as a bed surface), and a displacement system that makes a relative displacement between the device and the wave source.

[0098] C. High-energy ultrasonic conduction structure and conduction medium ...

Abstract

A method for measuring local temperature in human body or animal body includes emitting the first ultrasonic ray on measured region of temperature T, receiving reflected echo for obtaining the first parameter, changing temperature at measured region to be T+delta T and emitting the second ray for obtaining the second parameter, solving out measuring ratio and theoretical ratio of the two parameters, optimizing deviation between the two ratios for reverting out local temperature increment delta T of measured region.

Description

technical field [0001] The present invention relates to the method for non-invasively measuring the temperature in the body of a human body or an animal. Specifically, it relates to the application of high-intensity focused ultrasound (HIFU) to generate high temperature in the body of a human (animal) to kill the diseased tissue in the treatment area. In order to measure the temperature here, The invention proposes a non-invasive measurement method for ultrasonic inversion and a corresponding device. Background technique [0002] At present, focused ultrasound therapy device is one of the hot spots of medical research at home and abroad, and its clinical application has achieved good results. High Intensity Focused Ultrasound (HIFU) generates high temperature in the human (animal) body to kill the diseased tissue in the treatment area. If the temperature is too low, it will not be able to kill cancer cells, so the curative effect is poor. If the temperature is too high, it w...
