Abstract
An apparatus and method for using rotating shield brachytherapy (RSBT). In an aspect, the RSBT system and method can be used to maintain or increase tumor dose relative to conventional techniques with a dramatic reduction in radiation dose to the urethra, rectum, and bladder in the treatment of prostate cancer through placing partially shielded radiation sources away from sensitive tissues. In an aspect, the invention is an apparatus and method for the precise angular and linear positioning of multiple partially-shielded radiation sources in interstitial needles. In a further aspect, the invention comprises a monitoring and control apparatus for the precise and simultaneous angular positioning of multiple shield-containing catheters in the RBST system by measuring and correcting deviations between actual and desired catheter angular positions and depth in real time before and during treatment delivery.
