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