1. A method of imaging a patient to whom a radionuclide has been administered, comprising:
- positioning a detector carrier member, carrying one or more detectors, about the patient so that the carrier member encompasses at least 180°
of an arc about an axis through a target area of the patient'"'"'s body; and
taking a plurality of readings of gamma ray emissions from the radionuclide at detection positions corresponding to positions of the one or more detectors along the carrier member;
wherein the carrier member remains substantially immobile relative to the patient while the plurality of readings are taken;
and wherein the one or more detectors are capable of moving along the carrier member.

Abstract
A single photon emission computer tomography (SPECT) imager for the study of a patient to whom a radionuclide has been administered. The imager has an arcuate detector carrier encompassing at least 180° of arc about an examination axis through a target area of the patient. One or more scintillation detectors are carried by the detector carrier for taking a plurality of readings of gamma ray emissions from the radionuclide. While the plurality of readings are taken, the carrier remains substantially immobile relative to the patient.
