Unlocking Precision: Innovations in Room-Temperature Semiconductor Detectors for Cutting-Edge PET Imaging

Industry: This paper explores the evaluation of room-temperature semiconductor detectors
for ultrahigh-resolution positron emission tomography (PET) imaging. The focus is on enhancing
PET technology, which plays a crucial role in medical imaging for diagnosing diseases.

Challenge: One major challenge in PET imaging is accurately determining the depth of
interaction (DOI) of detected photons within the detector. Existing methods for obtaining DOI
information are complex and costly, leading to a need for simpler and more efficient solutions.

Extraordinary Aspects of the Paper: Two innovative methods for extracting DOI information
are presented: CR-RC filtering and DOI curve model. These methods offer a simpler and more
cost-effective means of achieving good DOI resolution compared to existing techniques. The
integration of DOI information into PET system calibration algorithms shows promising results
for enhancing PET imaging spatial resolution. Additionally, the potential future directions include
further testing with complex phantoms, integrating DOI information into calibration and image
reconstruction, and developing the PET system into a full ring configuration for increased
sensitivity.
Overall, this research demonstrates significant progress in improving the spatial resolution of
PET imaging using room-temperature semiconductor detectors, paving the way for more
precise disease diagnosis and treatment monitoring in the medical field.
