FIELD: physics.
SUBSTANCE: system for radiation treatment of affected skin areas contains a small-sized mobile basic module containing at least one processor for performing data collection and processing operations used during planning and delivery of radiation treatment, a high-frequency ultrasound image forming device connected to the main module via a wire, which is designed to scan and collect image data relating to the anatomy and topology of the patient's skin, and to supply image data to at least one processor, wherein the high-frequency ultrasonic device designed to operate at an ultrasonic frequency in the range from 20 to 70 MHz to produce images of the affected area, present within at least one of the skin layers selected from the group consisting of epidermis, deris and subdermis. Processor is configured to execute instructions saved in a memory unit, for performing operations including reception of a plurality of two-dimensional image layers from high frequency ultrasonic imaging device, wherein each image layer passes through the specified plurality of skin layers, separation of the affected area inside the skin layers, which includes edges of the affected area, in each of the plurality of two-dimensional image layers to obtain a plurality of processed image layers, integration of at least a part of the plurality of two-dimensional image processed layers to form a three-dimensional model of the affected area, which includes parts under the affected area surface and edges under the affected area surface inside the plurality of skin layers, analysis of the three-dimensional model of the affected area inside the plurality of skin layers to determine affection type, affected area dimension, affected area edges and affected area depth, determination of therapeutic dosimetry, wherein parameters of the therapeutic dosimetry include energy level, dose location and three-dimensional dose boundaries set inside the plurality of skin layers, a radiotherapeutic device mounted on a small-sized mobile main module, comprising a therapeutic bar and a therapeutic head, wherein the therapeutic bar is made swivel, at least one positioning system, configured to obtain positional data and adjust the therapeutic head in accordance with the dose location and the three-dimensional dose boundaries for the affected area. The system is equipped with a device readable by a computer. The method for treating the affected skin area involves the use of the system.
EFFECT: expansion of the range of technical means for radiotherapy with ultrasound control.
