Preclinical NEMA image quality phantom PET data

This is a preclinical positron emission tomography (PET) dataset containing the list-mode data of a NEMA image quality phantom measured with the preclinical Siemens Inveon PET scanner. Included are the list-mode datafile (.lst), sinogram file (.scn) created by the Siemens Inveon Acquisition workplace (IAW) software, MAP-OSEM3D reconstruction (.img) created by IAW, scatter correction sinogram (_sct.scn) created by IAW and the attenuation correction UMAP-file (.img) created by IAW. All the corresponding header files are included that contain all the relevant information, with the exception of reading the binary list-mode data. For documentation on reading the list-mode binary data, please ask Siemens. No normalization data is included in this dataset. You can, however, use the normalization data from Preclinical PET data. This dataset can be used in the OMEGA software, including the list-mode data, to import the data to MATLAB/Octave, create sinograms from the list-mode data and reconstruct the imported data. For help on using the dataset with OMEGA, see the wiki. The CT data, that was used to create the UMAP-file, is available from https://zenodo.org/record/4646835. The measurement data was collected by Jarmo Teuho.

本数据集为临床前正电子发射断层扫描（positron emission tomography，PET）数据集，包含使用西门子临床前Inveon PET扫描仪采集的NEMA图像质量体模的列表模式数据。所包含的数据文件有：由西门子Inveon采集工作站（Inveon Acquisition Workplace，IAW）软件生成的列表模式数据文件（.lst）、正弦图文件（.scn）；由IAW生成的MAP-OSEM3D重建文件（.img）、散射校正正弦图（_sct.scn），以及由IAW生成的衰减校正UMAP文件（.img）。所有配套头文件均已提供，涵盖全部相关信息，但二进制列表模式数据的读取方法除外。如需了解二进制列表模式数据的读取文档，请咨询西门子。本数据集未包含归一化数据，但可使用现有临床前PET数据集的归一化数据替代。本数据集可配合OMEGA软件使用，通过导入列表模式数据，即可将数据导入MATLAB/Octave环境、从列表模式数据生成正弦图，并对导入数据进行重建。如需了解OMEGA软件的数据集使用帮助，请参阅其维基页面。用于生成UMAP文件的CT数据可从https://zenodo.org/record/4646835获取。本测量数据由Jarmo Teuho采集。
