由于CT扫描被大量的应用于校正放射治疗计划中的组织不均匀性，因此获取CT值(亨斯菲尔德单位)和电子密度之间的精确关系显得尤为重要。062M型电子密度模体可提供CT值与各种组织的电子密度之间精准的相关性信息。该模体由美国CIRS公司生产的组织等效材料制造而成。
Because CT scans are used to correct for tissue inhomogeneities in radiotherapy treatment planning, it is important to obtain a precise relationship between CT number (in Houndsfield units) and electron densities. The Model 062M Electron density phantom enables precise correlation of CT data to electron density of various tissues. The phantom is manufactured from CIRS Tissue Equivalent Materials.
062M型电子密度模体由两个可相互嵌入的塑料水等效体构成，用于模拟头部及腹部生理特征。9组不同的组织等效电子密度插件可放置于扫描场内17处不同的位置。此外，该模体还包括一个水瓶插件，可填充各种液体。选配的距离标志插件可用于快速评估CT扫描仪的距离测量精度。
The Model 062M consists of two nested disks made from Plastic Water® -LR. They can represent both head and abdomen configurations. Nine different tissue equivalent electron density plugs can be positioned at 17 different locations within the scan field. Included is a water vial plug that can be filled with any fluid. Optional distance marker plugs enable quick assessment of the CT scanner’s distance measurement accuracy.
执行放射治疗计划的物理s师需要准确的工具来评估CT扫描数据，纠正不均匀性，并记录CT值与组织密度之间的关系。为了提高治疗计划的准确性，请使用CIRS 062系列电子密度模体。
Physicists performing treatment planning need accurate tools to evaluate CT scan data, correct for inhomogeneities and to document the relationship between CT number and tissue density. To improve the accuracy of your treatment planning, consider the CIRS Model 062 Electron Density Phantom.
注：062M型只是完整的锥束CT电子密度&图像质量模体系统三种配置之一。
The 062M is just one of three configurations available as a part of the Cone Beam CT Electron Density & Image Quality Phantom System.
