    摘要: The invention provides for a medical instrument (200, 300, 400, 500, 600, 700) comprising a magnetic resonance imaging system (204) operable for acquiring magnetic resonance data (266) from a subject (236) within an imaging zone (232) and an external beam radiotherapy system (202) operable for irradiating a target zone (238) within the imaging zone. The medical instrument further has a radiation beam generation system (208, 302, 302′, 302″) operable for generating a radiation beam (242, 304, 304′, 304″) and a radiation beam detection system (243, 502, 502′) operable for acquiring radiation beam detection data (270) descriptive of the radiation beam. Instructions cause a processor (248) controlling the instrument to receive (100) planning data (260) descriptive of a spatially dependent radiation dose and generate (102) external beam radiotherapy control commands (264) using the radiation dose. The instructions causes the processor to repeatedly: control (106) the external beam radiotherapy system to irradiate the target zone using the external beam radiotherapy system control commands; generate (108) the radiation beams using the radiation beam generation system; measure (110) the radiation beam detection data using the radiation beam detection system; acquire (112) the magnetic resonance imaging data using the magnetic resonance imaging system, generate (114) a magnetic resonance image (268) using the magnetic resonance image data, determine (116) a registration (274) of the magnetic resonance image to the radiation beam detection data; calculate (118) a mapping (276) using the registration; and modify the external beam radiotherapy system control commands using the mapping.

    摘要: The invention provides for a medical instrument (400, 500, 600, 700) comprising a magnetic resonance imaging system (404) and an external beam radiotherapy system (402) for irradiating a target zone (438) of a subject with a beam (442) of ionizing radiation within the imaging zone. The medical instrument further comprises a processor (448) for controlling the medical instrument. Execution of instructions cause the processor to: acquire (100, 200) first magnetic resonance data (458); reconstruct (102, 202) a first magnetic resonance image (460) from the first magnetic resonance data; receive (104, 204) planning data (462), wherein the planning data specifies a spatially dependent radiation dose for the target zone; register (106, 206) the planning data to the first magnetic resonance image; and calculate (108, 208) an external beam dosage plan (468) and a brachytherapy dosage plan (468) using the spatially dependent radiation dose and the first magnetic resonance image.

    摘要: A magnetic resonance (MR) system (10) for guidance of a shaft or needle (16) to a target (14) of a subject (12) is provided. The system includes a user interface (76). The user interface (76) includes a frame (78) positioned on a surface of the subject (12). The frame (78) includes an opening (82) over an entry point of a planned trajectory for the shaft or needle (16). The planned trajectory extends from the entry point to the target (14). The user interface (76) further includes one or more visual indicators (80) arranged on the frame (78) around the opening (82). The one or more visual indicators (80) at least one of: 1) visually indicate deviation of the shaft or needle (16) from the planned trajectory; and 2) visually indicate a current position of a real-time slice of real-time MR images.

    摘要: A medical apparatus (1100) comprising a magnetic resonance imaging system and an interventional device (300) comprising a shaft (302, 1014, 1120). The medical apparatus further comprises a toroidal magnetic resonance fiducial marker (306, 600, 800, 900, 1000, 1122) attached to the shaft. The shaft passes through a center point (610, 810, 908, 1006) of the fiducial marker. The medical apparatus further comprises machine executable instructions (1150, 1152, 1154, 1156, 1158) for execution by a processor. The instructions cause the processor to acquire (100, 200) magnetic resonance data, to reconstruct (102, 202) a magnetic resonance image (1142), and to receive (104, 204) the selection of a target volume (1118, 1144, 1168). The instructions further cause the processor to repeatedly: acquire (106, 206) magnetic resonance location data (1146) from the fiducial marker and render (108, 212) a view (1148, 1162) indicating the position of the shaft relative to the target zone.
