Design and Development of a 3D Position-Sensitive Detector for 4π View Gamma Imager Based on Dual-Ended Readout Technique
Peng Fan,Zhenlei Lyu,Tianpeng Xu,Yifan Hu,Qingyang Wei,Zhu Chenglin,Lixiang Jiang,Yan Xia,Yaqiang Liu,Tianyu Ma +9 more
TL;DR: In this paper, a 3D position-sensitive detector for the 4π view gamma imager based on dual-ended readout (DER) technique is proposed, which is composed of a GAGG block coupled to an SiPM array at both crystal ends.
Proceedings ArticleDOI
A new module-level parameter interfusion ratio (IR) to evaluate the performance of PET detector block
TL;DR: In this paper, an estimation parameter Interfusion Ratio (IR) was proposed to evaluate the level of miscoding with the help of IR to quantitatively compare the performance of different types of scintillator, different glued reflector types of crystals, different LUT of detectors.
Proceedings ArticleDOI
3D molecular breast imaging using a high-resolution dedicated cardiac SPECT camera
Hui Liu,Chung Chan,Yariv Grobshtein,Tianyu Ma,Yaqiang Liu,Shi Wang,Peter L. Kench,Albert J. Sinusas,Chi Liu +8 more
TL;DR: The preliminary results suggest that it may be feasible to detect sub-cm breast tumors located at both central breast and chest wall using the dedicated cardiac SPECT system investigated.
Journal ArticleDOI
Self-Collimating SPECT With Multi-Layer Interspaced Mosaic Detectors
Tianyu Ma,Qingyang Wei,Zhenlei Lyu,Debin Zhang,Hongyang Zhang,Rui Wang,Jiahong Dong,Yaqiang Liu,Rutao Yao,Zuo-Xiang He +9 more
TL;DR: In this paper, a self-collimating single photon emission computed tomography (SPECT) system was proposed to simultaneously achieve high resolution and sensitivity by using sensitive detectors constructed in a multiple-in-different-spaces (MATRICES) architecture to accomplish part of the collimation needed.
