In SPECT, ________ detectors are used to produce tomographic images

Explanation:
Tomographic imaging in SPECT relies on collecting gamma-ray projections from different directions as the detector(s) rotate around the patient. Even a single rotating detector can gather enough angular views to reconstruct cross-sectional images. Many systems use two or three detectors to capture multiple angles at once and speed up acquisition, but a large number of detectors isn’t required to produce tomography. The essential idea is sampling from multiple angles to enable reconstruction, not having a high count of detectors.
