FIELD: medicine.
SUBSTANCE: invention refers to medical equipment, namely to radiotherapeutic methods and systems. A radiotherapeutic method consists in ionising radiation pulse beam injection into an object for a pulse interval, obtaining a sampled data array of magnetic-resonant visualisation and restoring the data array with MR image formation. The sampled data array is obtained for an interval of sampled MR data longer than pulse intervals, with the sampled interval overlapping some of the pulse intervals. The data array is restored without the changed sampled MR-visualisation data obtained within the time periods of obtaining the data overlapped by the pulse intervals. The system comprises a radiotherapeutic subsystem, a MR-visualisation subsystem, a synchro unit and a restoring processor.
EFFECT: using the invention enables reducing the time of the radiotherapeutic session.
