FIELD: medicine.
SUBSTANCE: group of inventions relates to medical equipment, specifically to means of using capacitive micromachined transducers for high intensity focused ultrasound. Ultrasound medical instrument comprises a high intensity focused ultrasound system, comprising an ultrasound transducer with an adjustable sonication frequency, wherein the ultrasound transducer comprises a first array of capacitive micromachined transducers, a processor for controlling the medical instrument, memory for storing machine executable instructions. Execution of the instructions causes the processor to receive a treatment plan descriptive of a target zone within a subject, determine a traversal distance through the subject to the target zone using the treatment plan, determine a sonication frequency using the traversal distance, sonicate the target zone using the high intensity focused ultrasound system at the sonication frequency. Medical instrument includes an integrated circuit for controlling the sonication frequency of each of said capacitive micromachined transducers based on the calculation from the traversal distance of sonication of the micromachined transducer. Computer-readable storage medium is included in the ultrasound medical instrument. Control method is determined by the operation of the ultrasound medical instrument.
EFFECT: use of the group of inventions makes it possible to increase the amount of energy released in the target zone as the temperature gradient between the target and protected areas increases.
