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 the imaging system of a region of interest (40)
in an image generated by the x-ray sub-system (22). The region of interest
(40) is precisely targeted using the control console (26) for imaging
by the nuclear camera (50).
