METHOD AND APPARATUS FOR ULTRASOUND SUPPLY TO TISSUE Russian patent published in 2011 - IPC A61N7/00 A61B8/00 

FIELD: medicine.

SUBSTANCE: invention refers to medical equipment, namely to apparatuses and methods for ultrasound supply to tissue. A method of ultrasonic head control aims at ultrasound supply to tissue of the preset thermal action and the preset mechanical effect on tissue. Ultrasonic pulses have duration (T1) and recurrence interval (T2) with an ultrasonic carrier frequency coefficient (T1/T2) is specified as a function of ultrasonic thermal action and mechanical effect. According to the second version, the method of control provides the preset thermal action on tissue at its preset depth. The ultrasonic pulses are supplied consistently at related duration (TP1, TP2) and at related different ultrasonic frequencies (f1, f2). The relation (TP1/TP2) of ultrasonic pulse durations are specified in the form of a function of the preset tissue depth (z) and ultrasonic frequencies (f1, f2). The apparatus for ultrasound supply to tissue according to the methods comprise an entry device for specifying mechanical effect and thermal action, and/or depth of therapy, an ultrasonic head and a control which at the preset thermal action and mechanical effect generates control signals so that the ultrasonic head emits the ultrasonic pulses preset as a function of thermal action and mechanical effect for the first version. For the second version, the ultrasonic head emits the ultrasonic pulses having the related pulse duration and various ultrasonic frequencies (f1, f2) preset as a function of depth and ultrasonic frequencies. The machine-readable data carriers containing a computer program put to the memory in the machine-readable form, and provide implementation of the methods by the first and second versions.

EFFECT: use of the invention allows carrying out flexible processing depth adjustment matched with therapeutic requirements.
