REAL-TIME HIFU THERAPY MONITORING AND CONTROL IN SET OF MEASUREMENTS Russian patent published in 2016 - IPC A61N7/02 A61B8/00 

FIELD: medicine.

SUBSTANCE: device comprises an ablation unit accommodating a therapeutic grid and multiple-element diagnostic grid confocally mounted with the therapeutic grid which emits a therapeutic energy transfer beam to change the mechanical property of a biological tissue and a push beam based on an acoustic emission force to assess the effects of the therapeutic beam. The therapeutic beam has the last focal point. A control device comprises a combination unit of a matching circuit and multichannel amplifier, a logical start and control unit, and an ultrasound data multichannel collection and analysis unit. The logical launch and control unit produces start and control signals to provide timing and electronic control of the three types of the acoustic beams including the therapeutic beams, push beams and tracking beams which alternate. The combination unit of the matching circuit and multichannel amplifier responds to the start and control signals supplied by the logical start and control unit to apply excitation signals to the therapeutic grid. The ultrasound data multichannel collection and analysis unit responds to the start and control signals to electronically control the tracking beam to control a measurement in a specific location displaced from the last focal point of the therapeutic beam in at least one of the directions in azimuth and lift, and - to the target periphery of an injury formed by the therapeutic beam. The tracking beam tracks the change caused by pushing the above biological tissue in response to the push beam based on the acoustic emission force apart from the therapeutic beam.

EFFECT: using the invention enables to provide high accuracy when determining the stop time of tissue ablation in the ablation point.
