Abstract
A simulation/generation/verification system for blocker patterns and blockers for use in radiation therapy comprises a fluoroscopic simulator apparatus, a computer system for acquisition and processing of fluoroscopic images, a manual input device for superposing blocker pattern outlines onto such images, display and storage devices for such images, apparatus for automatic cutting of blocker contour templates, blocker patterns and blockers, and apparatus for verification thereof. The system also facilitates acquisition of compensator contours and generation of corresponding compensator filters for incorporation with blockers. The system facilitates simulation, generation, and verification of blocker patterns or blockers per se in one substantially continuous procedure that minimizes intervening manual steps, while a patient is aligned within the system during an uninterrupted session. Computer-aided and computer-controlled fluoroscope image composition, linearization, enhancement and manipulation, marking of target field, acquisition and appropriate manipulation and superposition of compensator contour information, recording of all of such information and use thereof for automatic …
