TARGET TRACKING APPARATUS FOR RADIATION TREATMENT PLANNING AND DELIVERY

摘要

A target treatment apparatus for treating a target region ( 130 ) within a subject ( 140 ) is provided. The apparatus includes an MRI apparatus ( 100 ) for generating MR images during an MR scan of the subject disposed within an examination region ( 110 ). The apparatus further includes an MRI localizer ( 150 ) for receiving the image data from the MRI apparatus wherein the target ( 130 ) is localized and a reference marker localizer ( 160, 160 ') for non-invasively receiving reference data from a plurality of reference points disposed in proximity to the target wherein the reference points are localized. A tracking processor ( 300 ) is also included in the apparatus for receiving localized data from the MRI localizer wherein a relationship between the reference markers and the target region is generated.
