The detector in single-photon emission computed tomography has played a key role in
the quality of the images. Over the past few decades, developments in semiconductor
detector technology provided an appropriate substitution for scintillation detectors
in terms of high sensitivity, better energy resolution, and also high spatial resolution.
One of the considered detectors is cadmium telluride (CdTe). The purpose of this paper
is to review the CdTe semiconductor detector used in preclinical studies, small organ
and small animal imaging, also research in nuclear medicine and other medical imaging
modalities by a complete inspect on the material characteristics, irradiation principles,
applications, and epitaxial growth method.
