Medical equipment for external beam radiation therapy and brachytherapy

摘要

The present invention provides medical devices (400, 500, 600, 700). The medical device includes a magnetic resonance imaging system (404) and an external beam radiation therapy system (402) that irradiates a subject's target zone (438) with an ionizing radiation beam (442) in the imaging zone. The medical device further includes a processor (448) that controls the medical device. Execution of the instructions causes the processor to: obtain first magnetic resonance data (458) (100, 200); to reconstruct a first magnetic resonance image (460) from the first magnetic resonance data (102, 202). ); Receiving plan data (462), the plan data specifying a spatially dependent radiation dose of the target zone (104, 204); registering the plan data with the first magnetic resonance image (106, 206); The external beam dose plan (468) and the brachytherapy dose plan (468) are calculated using the space-dependent radiation dose and the first magnetic resonance image (108, 208).
