Abstract

The invention provides a real-time ultrasonic energy monitor and method used in real-time monitoring the work condition of the ultrasonic generator during high strength focus ultrasonic treating course. It comprises a vibration sensor, a vibration press fixed on the ultrasonic generator or the ultrasonic propagation sound field used to test the vibration press of the ultrasonic and transfer it into electric signal and output it, a signal amplifying circuit which is connected with the vibration sensor and is used to amplify and output the electric signal of the vibration sensor and a signal collecting circuit which is connected with the signal amplifying circuit and is used to test the frequency of the ultrasonic and the frequency and voltage value of the amplitude from the electric signal of the signal amplifying circuit and output it to the computer so that the computer can quote the work condition of the ultrasonic generator by the tested frequency and amplitude.

Description

technical field [0001] The invention relates to a real-time ultrasonic energy monitoring device and method, in particular to a real-time ultrasonic energy monitoring device and method for an ultrasonic generator in a high-intensity focused ultrasonic treatment system. Background technique [0002] Medical research has found that the heat resistance of tumor cells is worse than that of normal cells. In a temperature environment above 42.5°C, tumor cells die within 30 minutes, while normal cells are slightly damaged and reversible. Based on this characteristic of tumor cells, the high-intensity focused ultrasound tumor therapy system uses ultrasound as the energy source, uses its penetrability and focusability, and couples the ultrasound with low average sound intensity emitted by the probe through the medium and passes through the skin. Enter the human tumor tissue, focus or converge to a spatial point to form an average sound intensity of 1000W / m 2 The above focal region (f...
