PET/CT scanner instrumentation, challenges, and solutions - 24/08/11
, Phillip M. Cheng, MD a, Hubert Vesselle, MD, PhD a, Joel S. Karp, PhD bRésumé |
PET/CT scanners offer a hardware solution for aligning and viewing functional and anatomic images that is immune to many of the errors in strictly software registration techniques. Moreover, PET attenuation-corrected emission scans benefit from the use of the onboard CT for fast, low-noise attenuation correction. Along with the significant improved localization and reduced acquisition time, PET/CT scanners also introduce new instrumentation challenges ranging from patient movement to quantitative attenuation correction. This article provides an overview of current PET/CT scanner technology, a discussion of challenges faced by these systems, and pending solutions.
