A virtual C-arm support system

40

is used in a radiographic imaging apparatus of the type including an x-ray source

44

and an x-ray detector

48

. The support system includes a first positioning system

42

operatively connected to the x-ray source for selectively positioning the x-ray source in a range of first orientations

120, 140, 170

relative to the examination region E. A second positioning system

46

is operatively connected to the x-ray detector

48

for selectively positioning the x-ray detector in a range of second orientations

122, 142, 172

relative to the examination region E. A control unit

60

is in operative command of at least one of the first and second positioning systems to maintain a predetermined spatial relationship between the x-ray source and the detector for each of the ranges of the first and second orientations relative to the examination region. In a second embodiment, the control unit is in operative command of only the first positioning system, the second positioning system being manually movable. The control unit maintains a predetermined spatial relationship between the x-ray source and detector by moving the x-ray source in response to manual movement of the x-ray detector for each of the ranges of first and second orientations of the source and detector relative to the examination region.
