Cadmium Telluride Semiconductor Detector for Improved Spatial and Energy Resolution Radioisotopic Imaging
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 (...
متن کاملEvaluation of a small cadmium zinc telluride detector for scintimammography.
UNLABELLED The purpose of this study was to evaluate a small semiconductor-based gamma camera that may have applications in scintimammography. METHODS A small cadmium zinc telluride (CZT) detector was evaluated. The detector had a field of view of 20 x 20 cm with detector elements of 2.5 x 2.5 mm in size. Both short-bore (35 mm) and long-bore (50 mm) collimators, matched to the geometry of th...
متن کاملStudy of a high-resolution, 3D positioning cadmium zinc telluride detector for PET.
This paper investigates the performance of 1 mm resolution cadmium zinc telluride (CZT) detectors for positron emission tomography (PET) capable of positioning the 3D coordinates of individual 511 keV photon interactions. The detectors comprise 40 mm × 40 mm × 5 mm monolithic CZT crystals that employ a novel cross-strip readout with interspersed steering electrodes to obtain high spatial and en...
متن کاملThe Cadmium Zinc Telluride (CZT) Detector Array Innovation Pathway
This pathway describes the development of soft gamma-ray/hard x-ray detector arrays at NASA’s Goddard Space Flight Center (GSFC, or Goddard), through a collaboration between the gamma-ray spectroscopy group and the detector branch. The Cadmium Zinc Telluride (CdZnTe, or CZT) detectors which resulted from this decade-long development were first flown on the wildly successful SWIFT mission in 200...
متن کاملX-ray Energy Response of Mercury Cadmium Telluride Near-infrared Detector Arrays
A technique involving Fe X-rays provides a straightforward method to measure the response of a detector. The detector’s response can lead directly to a calculation of the conversion gain (e ADU), as well as aid detector design and performance studies. We calibrate the Fe X-ray energy response and pair production energy of HgCdTe using 8 HST WFC3 1.7 μm flight grade detectors. The results show t...
