FIELD: physics.
SUBSTANCE: device contains a magnetic-resonance imaging system for magnetic resonance data collection from the subject in the area of visualization, a system of focused high intensity ultrasound, a processor, wherein the execution of commands causes the processor to control the magnetic-resonance imaging system to collect magnetic resonance data using a pulse sequence. The pulse sequence contains a pulse imaging sequence using acoustic radiation force that contains an exciting pulse, a multi-dimensional gradient pulse applied during the radio frequency excitation of an area of interest which is two-dimensional, so the area of interest has a two-dimensional cross section. The two-dimensional cross-section has a rotational symmetry about the axis of the area of interest, wherein the axis of the area of interest and the axis of the beam are coaxial. The area of interest comprises a predetermined volume that encompasses the target zone and at least a portion of the beam axis. The processor also controls the system of focused high-intensity ultrasound for ultrasonic processing of the target zone so that the ultrasonic processing of the target zone occurred during the pulse imaging sequence using the acoustic radiation force and the image obtained using the impact force is reconstructed, using the magnetic-resonance imaging data. In a medical device operating using a computer-readable medium, a method of operating a medical device for magnetic-resonance imaging using the acoustic radiation force is performed.
EFFECT: group of inventions allows to reduce the time of designing the image in real time.
