Credence Cartridge Radiomics Phantom CT Scans

<p>This collection consists of 17 CT scans of the Credence Cartridge Radiomics (CCR) phantom, which was designed for use in studies of texture feature robustness. The scans were acquired at four medical centers using each center’s chest protocol and were taken using GE (7 scans), Philips (5 scans), Siemens (2 scans), and Toshiba (3 scans) scanners. The CCR phantom has 10 cartridges, each with a unique texture, Fig 1. The first four cartridges are 3D printed ABS plastic with 20%, 30%, 40%, and 50% honeycomb fill, and they provide regular, periodic textures. The next three cartridges provide natural textures: sycamore wood, cork, and extra dense cork. A cartridges of shredded rubber particles provides textures similar to those of non-small cell lung cancer. The ninth cartridge is solid, homogenous acrylic and provides a minimal texture control. Finally, the tenth cartridge is 3D printed plaster with the highest electron density (400 – 600 HU) and is intended to be more similar to bone.</p><p>In addition to the DICOM images for the 17 scans, this collection also contains two sets of contours as DICOM RT structure files. The first set provides 8x8x2 cm<sup>3</sup> contours for each cartridge in each scan. The second set provides 16 adjacent 2x2x2 cm<sup>3</sup> contours for each cartridge in each scan. Researchers studying radiomics will be able to evaluate features for robustness across a variety of scanners. Features can be calculated using the researchers own software or third party software such as <a href="https://sourceforge.net/projects/ibex-mda/?source=directory">IBEX (imaging biomarker explorer)</a>.</p><p><strong>Related publications:</strong></p><p>Mackin, D., Fave, X., Zhang, L., Fried, D., Yang, J., Taylor, B., Rodriguez-Rivera, E., Dodge, C., Jones, A.

本数据集包含17张Credence Cartridge Radiomics（CCR）模拟物的CT扫描图像，该模拟物专为纹理特征鲁棒性研究而设计。这些扫描图像在四个医疗中心使用各自中心的胸部成像方案获取，分别使用GE（7张扫描）、Philips（5张扫描）、Siemens（2张扫描）和Toshiba（3张扫描）的扫描仪进行。CCR模拟物包含10个容器，每个容器具有独特的纹理，如图1所示。前四个容器由3D打印的ABS塑料制成，填充率分别为20%、30%、40%和50%的蜂窝结构，它们提供规则、周期性的纹理。接下来的三个容器提供自然纹理：梓木、软木和超密软木。一个由橡胶碎片制成的容器提供了与非小细胞肺癌相似的纹理。第九个容器为均质丙烯酸固体，提供最小的纹理控制。最后，第十个容器为3D打印的石膏，具有最高的电子密度（400-600 HU），旨在更接近骨骼。除了17张扫描的DICOM图像外，该数据集还包含两组轮廓，作为DICOM RT结构文件。第一组为每个扫描中的每个容器提供8x8x2立方厘米的轮廓。第二组为每个扫描中的每个容器提供16个相邻的2x2x2立方厘米的轮廓。从事放射组学研究的研究人员将能够评估跨多种扫描仪的鲁棒性特征。特征可以通过研究人员自带的软件或第三方软件（如<a href="https://sourceforge.net/projects/ibex-mda/?source=directory">IBEX（成像生物标志物探索器）</a>）进行计算。
