RECOGNIZING A REAL WORLD FIDUCIAL IN PATIENT IMAGE DATA

摘要

Medical apparatus is described including a fiducial component and a posit ion sensor. The component is recognizable as at least a part of a fiducial w hen appearing in image data of a patient. The component is attachable to the patient. The sensor is attachable to the component at a predetermined locat ion and orientation on the component or is capable of being positioned adjac ent the fiducial component without attachment thereto at a predetermined loc ation and orientation. A storage medium is described containing a program wh ich instructs the computer to recognize a predetermined shape of each of at least one portion of a position sensor as at least a part of a real-world fi ducial in image data of a patient. The position sensor is adapted to provide position data. Medical apparatus which includes the position sensor and the storage medium is also described.
