1. A medical instrument (900, 1000), comprising: a system (911) of high-intensity focused ultrasound containing an ultrasonic transducer (102, 104, 202, 204, 302, 407, 508) with an adjustable frequency of ultrasonic action for focusing ultrasound into the volume of ultrasound exposure, wherein said ultrasonic transducer contains a first lattice and a second lattice of capacitive micromechanical transducers (102, 104, 202, 204, 302, 407, 508)； - a processor (916) for controlling a medical instrument； - a memory (922) for storing machine - executed commands (930, 933, 934), and the execution of the instructions forces the processor to: - accept (700, 800) therapy plan (924), which characterizes the target zone (908) inside the subject (902)； - determine (702, 802) the distance ( 926) passing through the subject to the target zone using the treatment plan, and the distance of the passage characterizes the passage of ultrasound from the ultrasound transducer to the target zone； - determine (704, 804) the frequency (829) of the ultrasonic action using the distance to focus the volume of the ultrasonic air actions on the target zone； and - impact (706, 806) with ultrasound on the target area using a high-intensity focused ultrasound system at the frequency of ultrasonic exposure, and, each of the capacitive micromechanical ultrasonic transducers has a separately controlled frequency of ultrasonic exposure, and the execution of the instructions forces the processor to determine the frequency of ultrasonic exposure for each of the capacitive micromechanical ultrasonic transducer elements. 2. The medical tool according to claim 1, wherein the execution of the instructions causes the processor to determine1. Медицинский инструмент (900, 1000), содержащий:- систему (911) высокоинтенсивного сфокусированного ультразвука, содержащую ультразвуковой преобразователь (102, 104, 202, 204, 302, 407, 508) с регулируемой частотой ультразвукового воздействия для фокусирования ультразвука
