Positron emission tomography (PET) scanners with new features, such as open structure, compact size, and adaptive field of view (FOV), have attracted significant attention. Among these novel designs, panel PET has the potential to combine the open structure and variable FOV into a compact form. In this paper, we would like to further exploit these structural advantages by proposing a modified version,...
Measuring system response matrix (SRM) by Monte Carlo method is time and resource consuming, even with high performance computer nodes. In this paper, we exploited symmetry properties available to drastically reduce the complexity in computing SRM of panel PET, which has two parallel panel detectors. By extending the original system and simulating 4 voxels every slice parallel to the PET detector,...
With high specificity of tumor necrosis, hypoxia tissues and subclinical lesions, PET may have great potential for tumor surgery guidance. PET images in surgery will tell us how tissues change during the operation and whether the lesion has been cleared. We did research on panel PET guided therapy, and we have developed 3-dimensional reconstruction methods for panel PET systems. However we meet the...
In recent years, panel PET is an interesting field in medical imaging. But the major obstacle of panel PET is the limited view problem. Images reconstructed by traditional algorithms will suffer serious artifacts. Time-of-flight (TOF) information can be incorporated into the image reconstruction to remove the artifacts. However, the best system timing resolution available in current commercial PET...
An all-digital positron emission tomography (PET) scanner for imaging small animals has been developed at Huazhong University of Science and Technology (HUST). The implementation of block detector with position sensitive photomultiplier (PSPMT) and multi-voltage threshold (MVT) technology is presented in this paper. The detector comprises 12 basic detector modules (BDMs), which can be used to construct...
