ABSTRACT:
A combined imaging scanner is disclosed for fusing together image data obtained by a computed tomographic (CT) scanner and a single photon emission computed tomographic (SPECT) scanner. The diagnostic radiology imaging CT Scanner anatomical data provides a background map with which is convolved the radioscope distribution SPECT scanner data to yield a color shaded relief image which can then be printed on a laser film printer or other output device. Both sets of data are collected almost simultaneously while the patient is in a fixed position. The apparatus includes combined gantries supporting both CT and SPECT scanners, a computer, a printer and a table to slip through both gantries while holding the patient in a fixed position.
