Read more Background Photon Counting CT, an emerging imaging technique, promises enhanced spatial resolution, reduced radiation dose, and improved tissue characterization compared to conventional CT. Challenges in radiation exposure, image noise, and limited tissue differentiation persist in traditional CT. Dual-energy CT falls short in addressing these issues. Photon-counting CT emerges as a promising solution set to revolutionize medical imaging by overcoming these limitations, making it a transformative technology in the field.This review simplifies photon-counting CT's technical principles, offering insights into its current status...
Read more Findings and procedure details CT is widely utilized in medical diagnosis and therapy due to its rapid scanning, high spatial resolution, and widespread availability. Technological innovations over its 40-year history, particularly in CT detector technology, have expanded its applications. The x-ray detector, a crucial component, significantly influences image quality and radiation dose in CT scanners.Photon-counting detectors (PCDs) offer inherent advantages over traditional CT detectors.CONVENTIONAL ENERGY-INTERGRATING DETECTORS [fig 1] Clinical CT scanners currently utilize energy-integrating detectors (EIDs), each detector bank consisting of multiple rows of detector elements...
Read more Conclusion PCD-CT, converting X-ray photons directly, surpasses conventional EID CT with improved spatial resolution, enhanced iodine signal, noise elimination, and efficient dose usage. It achieves high spatial and temporal resolution with multi-energy assessment. PCD technology addresses artifacts like calcium blooming, benefiting larger patients and enabling radiation dose reduction in pediatrics. Applications span breast CT and various anatomical regions, offering potential benefits in reducing artifacts, enhancing vessel evaluation, improving contrast imaging with agents like gadolinium, and enabling molecular imaging with targeted nanoparticles...
