Problems solved by technology
[0006] 1) The process of obtaining the three-dimensional eigenvalues of the focused sound field is very time-consuming;
[0007] 2) The sound intensity energy in the focal region is too large, which may easily cause damage to the hydrophone;
[0009] 4) Since finite amplitude waves will produce waveform distortion during the propagation process, causing nonlinear phenomena such as harmonics, sound attenuation, and sound saturation, the results obtained by inferring the HIFU sound field through extrapolation will have large errors
[0025] None of the proposed measurement methods have been successfully applied to the measurement of HIFU sound field under high power

The invention discloses a high-intensity focused ultrasound measuring device and method and belongs to the technical field of high-intensity focused ultrasound measurement. The measuring device includes a container and further includes a measurement analysis system, an infrared imaging thermodetector, degassing treating water, an ultrasound absorber and a coupling medium. The container is dividedinto an upper portion and a lower portion by a coupling interface, the degassing treating water is positioned on the upper portion of the coupling interface, the ultrasound absorber is mounted on thesurface of the degassing treating water, the coupling medium is positioned on the lower portion of the coupling interface, and an HIFU probe is placed in the coupling interface. An HIFU control systemis connected with the HIFU probe and the measurement analysis system. The measurement analysis system is connected with the infrared imaging thermodetector. The high-intensity focused ultrasound measuring method is implemented through the high-intensity focused ultrasound measuring device. The high-intensity focused ultrasound measuring device and method are quick in measurement speed, large in measurement power range, high in spatial resolution, wide in applied ultrasonic frequency range and suitable for 'on-line' measurement of an HIFU device.
Description
technical field [0001] The invention specifically relates to a high-intensity focused ultrasound measurement device and method, and belongs to the technical field of high-intensity focused ultrasound measurement. Background technique [0002] High-Intensity Focused Ultrasound (HIFU), as a non-invasive treatment, can treat malignant tumors in organs or tissues such as liver, breast, pancreas, prostate, kidney, and bone. It is used for the treatment of brain nervous system diseases and brain tumors, as well as the switch control of the blood-brain barrier, providing clinicians with a new type of "green" physical therapy option in addition to surgery, radiotherapy and chemotherapy, and is being carried out at home and abroad. Extensive basic and clinically applied research. According to the statistics of the Focused Ultrasound Foundation, by the end of 2015, more than 100,000 patients worldwide have received focused ultrasound therapy, of which more than 25,000 patients in 201...
