Abstract:
A method for simultaneous transmission x-ray computed tomography (CT) and single photon emission tomography (SPECT), comprising the steps of:injecting a subject with a tracer compound tagged with a &ggr;-ray emitting nuclide; directing and x-ray source along an axis toward said subject; rotating said x-ray source around said subject; operating said x-ray source during said rotating step; rotating a single cadmium zinc telluride (CZT) two-sided detector on an opposite side of said subject from said source; simultaneously detecting, with respect to position and energy, each pulsed x-ray and each emitted &ggr;-ray captured by said single CZT detector during said rotating; recording data indicative of each said position and each said energy of each said captured x-ray and &agr;-ray; and, creating respective CT and SPECT images from said recorded data.
