Abstract
In radiation oncology, a magnetic resonance apparatus is used to plan a treatment regimen. The oncologist uses the features of slice width selection, and depth selection to better ascertain where a medical malignancy is within a patient. In order to facilitate a user-friendly atmosphere for the oncologist, a new user control interface (50) is added to an MRI apparatus that includes controls normally found on a typical oncology linear accelerator. A conversion algorithm (52) translates the linac input into an imaging region for a magnetic resonance sequence that images the malignancy. Along each planned treatment trajectory radiation and MR projection images are superimposed to delineate the malignancy clearly for beam aiming and collimation adjustments.
