Nowadays, time-of-flight (TOF) PET detectors and systems are becoming increasingly common since scintillators, photodetectors and electronics has made significant progress. It has been well recognized that TOF PET imaging can increase the image signal-to-noise ratio (SNR) and yield other benefits; and the degree of these enhancements is higher as the timing resolution improves. Previously we have...
Modular detectors have attracted extensive attention in position emission tomography (PET) system design. Various detector system layouts can be constructed from modular detectors to match the different performance requirements from different applications. In the modular detector design, the lightguide or the fiber is commonly used to construct large continuous arrays to eliminate the gaps introduced...
Super-resolution (SR) reconstruction technique is mainly a task of reconstructing high resolution images from a sequence of low resolution images. The super-resolution technique for H.264 compressed video has been focused by many researchers recently. This paper briefly analyzes the narrow quantization constraint set method (NQCS), and then, in consideration of motion characteristic information of...
