TracPETperf-D2-PhantomExperiments2

The objective of this study was to perform a standard acquistion of dynamic PET perfusion measurements at the Turku PET centre using a dynamic test object (also known as a flow phantom). Images were acquired following the experimental protocol described in D2 of this project which is linked below. Once unzipped. there is a list of subfolders that are named using the convention <em>SCANTYPE_PERCENTAGEFLOW_TOTALFLOW_FLOWINTUBE_RECONSTRUCTIONTYPE</em> This naming convention describes and relates to some of the factors that we are varying in the experimental design protocol, specifically: SCANTYPE: type of scan; in the example “PT” stands for PET PERCENTAGEFLOW: percentage of flow going into the phantom main compartment; in the example, this value can be 20, 40, 60 or 80 %. TOTALFLOW: total flow rate set at the flow pump; in the example, it can be 150, 200 or 250 ml/min. FLOWINTUBE: the flow that goes into input tube as opposed to that going into the main compartment TOTALFLOW - COMPARTMENTFLOW RECONSTRUCTION TYPE: PET image reconstruction algorithm; in the example, it can be BSREM or OSEM Within each folder there is a dynamic sequence of images, stored as “.dcm” These images can be processed using the sofware tool provided in the GitLab repo with link below.本研究旨在图尔库PET中心（Turku PET Centre）采用动态测试体（流动体模flow phantom）完成动态正电子发射计算机断层显像（PET）灌注测量的标准化采集。图像采集遵循本项目D2文档所载的实验方案，相关链接如下。解压后将得到一系列子文件夹，其命名遵循<em>SCANTYPE_PERCENTAGEFLOW_TOTALFLOW_FLOWINTUBE_RECONSTRUCTIONTYPE</em>规范。该命名规范对应并阐明了实验设计方案中我们所调控的部分参数，具体说明如下： SCANTYPE：扫描类型；示例中的“PT”代表PET扫描。 PERCENTAGEFLOW：流入体模主腔的流率百分比；示例取值可为20%、40%、60%或80%。 TOTALFLOW：流量泵设置的总流率；示例取值可为150、200或250 ml/min。 FLOWINTUBE：进入输入管的流率，即总流率减去体模腔流率（区别于流入主腔的流率）。 RECONSTRUCTION TYPE：PET图像重建算法；示例取值可为BSREM或OSEM。 每个文件夹内均存储有动态图像序列，文件格式为“.dcm”。上述图像可通过GitLab仓库中提供的软件工具进行处理，仓库链接如下。
