Abstract:
A diagnostic imaging method utilizing a gamma camera having first and second detectors disposed in a relative angular orientation with respect to an examination region, the first and second detectors having respective first and second radiation sensitive faces which face the examination region and first and second transverse fields of view, a region of interest within the examination region having a dimension greater than the first and second transverse fields of view, the method comprising:utilizing the first and second detectors to detect radiation indicative of radionuclide decays occurring within the examination region;rotating the first and second detectors about the examination region;repeating the steps of utilizing and rotating a plurality of times so as to detect radiation with the first and second detectors located at a plurality of projection angles;in coordination with the rotation of the first and second detectors about the imaging region, moving the first and second detectors in a transverse direction so that, at each of the projection angles, the effective transverse field of view of the first and second detectors includes the region of interest;reconstructing an image indicative of the detected radiation.
