Abstract
A diagnostic imaging system (20) comprising a computer workstation (26) for controlling the imaging system, interfacing with an operator and generating images. A coordinate system (100) is in data communication with the computer workstation. The coordinate system (100) is adapted to describe relative position of components in the diagnostic imaging system (20). A subject support (30) is describable within the coordinate system and an X-ray sub-system (22) is positionable around the subject support (30). Position sensors (44a) are operatively connected to the x-ray sub-system (22) and they provide signals to the workstation (26) indicative of the position of components of the x-ray sub-system (22) within the space represented by the coordinate system. A nuclear camera sub-system (24) is positionable around the subject support (30). Position sensors (44b) are operatively connected to the nuclear camera sub-system (24) and provide signals to the workstation (26) indicative of position of components of the nuclear camera sub-system within the coordinate system. The workstation (100) includes a region of interest position determination function (108) for determining the position within …
