SPECT质量控制通用测试系统模型和应用研究

单光子发射型计算机断层仪(SPECT)是现代核医学的先进诊断仪器,它的质量控制是其临床诊断质量的根本保证。SPECT质控包括仪器的验收测试,日常质控和性能检测三个方面,其主要内容就是按照SPECT的性能测试标准,对其性能指标进行检测和维护。目前国际公认的性能测试标准是美国电气制造商协会(NEMA)颁布的γ相机性能测试标准,该标准定义了γ相机和SPECT的各项性能指标及其测试方法和测试模型。本研究包括三项内容:(1)按NEMA     

SPECT的数据采集条件对其断层分辨率的影响实验探讨

目的：探讨采集条件的选择对ＳＰＥＣＴ断层分辨率的影响。方法：来用 Ｊａｓｚｃｚａｋ模型。设定不同条件对模型进行 ３６０°采集,并对所采集的４８组原始资料进行重建处理,观察重建图像。结果：配置高能准直器,１２８×１２８矩阵,２００Ｋ以上计数,重建结果可分辨出直径 １１ ｍｍ柱型模型及直径 １２ ｍｍ球形模型,其余采集方式所重建的结果均达不到此分辨效果。讨论;就矩阵大小而言,１２８×１２８矩阵采集分辨能力优于６４×６４矩阵。采集信息量的大小亦是影响分辨率好坏的重要因素之一,采集信息量大,分辨率则高;反之,则分辨率下降。     

预防脑出血病人便秘的护理

脑出血病人发病后需绝对卧床休息,病人因长期卧床、饮食结构及心理的改变,易引起便秘,导致血压波动、颅内压增高,部分病人会出现再出血,导致生命危险,所以预防便秘有利于预防再出血.现将我科2006年3月-2006年5月收治的30例脑出血病人预防便秘的护理报告如下.

双探头符合线路SPECT正电子显像衰减校正实验研究

Objective The photons from the body would be attenuated in their intensity by the soft tissue before they reach the detectors. Some of them lost more intensity than others when coming from the deeper body. Attenuation of the photons would distort the image, affect the image quality, and may lead to misdiagnosis. In this research the X-ray and γ-ray were used as transmission resources for accurate assess-ment of attenuation in each part of the body. The transmission data was used to correct the emission data from the body. Iteration algorithm was used for the reconstruction of attenuation corrected tomography ima-ges. Evaluate the efficacy of attenuation correction in duel head hybrid SPECT/coincidence PET systems (SPECT/PET) and SPECT using both the Jaszczak and the myocardial phantoms. Methods For PET phantom study, the Jaszczak phantom was filled with the aqueous solution of 18F-fluorodeoxyglucose (FDG) and was scanned with two hybrid SPECT/coincidence PET systems respectively (Vertex Plus, Netherlands Philips ADAC Company and Hawkeye, USA GE Company). The PET images were acquired and reconstruc-ted. Results The "cold" lesion, which the diameter was less than 12 mm of uncorrected image, could not be identified. But it, after correction, diameter 9 mm, would be recognized clearly, less than 7 mm would not be distinguished. Noncorrected image could only identify "hot" lesions which the diameter were 9, 12, 14, 18, 22 and 38 mm, while in the corrected image, not only it was much better, but also the "hot" le-sion of 6 mm was distinguished. In Hawkeye, the same situation, the corrected image of was improved obvi-ously; the disparity of counts between surrounding and deep center less, and the counts in deep center were compensated. There were only 3 round " cold" lesions could be recognized, the diameter: 14, 18 and 20 mm; all of them which diameter were less than 12 mm could not be distinguished. One in the center was al-most as background, and could not be identified. The radioactive accounts of surrounding and center were quite different. The corrected image 5 "cold" lesions could be found, 9, 12, 14, 18 and 20 mm, but7 mm could not be found. The noncorrected image, only 12, 14, 18, 22 and 38 mm " hot" lesions could be found, and by the surrounding, there was an arc shape "hot" lesion. But it could distinguish 9, 12, 14, 18, 22 and 38 mm "hot" lesions on the corrected image, and the image was much better than noncorrected one. Conclusions The corrected image of Vertex Plus was improved obviously with the disparity of counts between surrounding and deep center less, and the counts in deep center was compensated. The result of at-tenuation with phantom showed that 137Cs was better than CT in both image quality and spatial resolution.
