A therapeutic apparatus (400, 500) comprising a radiotherapy apparatus (402), a mechanical positioning system, and a magnetic resonance imaging system (404). The radiotherapy apparatus comprises a radiotherapy source (408). The radiotherapy apparatus is adapted for rotating the radiotherapy source at least partially around a subject support. The therapeutic apparatus further comprises a memory containing machine executable instructions (468, 470, 472, 474, 476). Execution of the instructions causes a processor to repeatedly: acquire (100) the magnetic resonance data using the magnetic resonance imaging system; reconstruct (102) a magnetic resonance image (460) from the magnetic resonance data; register (104) a location (462) of the target zone in the magnetic resonance image; generate (106) radiotherapy control signals (464) in accordance with the location of the registered target zone; generate (108) mechanical positioning control signals (466) in accordance with the registered target zone and the radiotherapy control signals; and send (110) the radiotherapy control signals to the radiotherapy system and send (110) the mechanical positioning control signals to the mechanical positioning system. |
