CORE--PHANTOM DEVELOPMENT

本核心的目标是提供质量一致的幻影， 这个项目中的所有项目。 本书中提出的幻影发展计划 核心的目的是开发一套对比度细节（CD）幻影 适用于超声成像和弹性成像。 标准 方法和材料将用于体模构造。 理想情况下，这些 phantomy将是热稳定和时间稳定的，并适用于CD 超声和弹性成像分析。 几种选择 提出了用于这些幻影的材料的组合。 建设 测试样品的数量是确定最佳材料组所必需的， 由此产生的幻影的寿命和一致性。 以下 施工与测试样品性能的最佳组合 材料的选择，并构建CD模型。

The objective of this Core is to provide phantoms of consistent quality to all projects in this program. The phantom development proposed in this core is aimed at developing a set of contrast-detail (CD) phantoms applicable to both sonographic and elastographic imaging. Standard methods and materials will be used in phantom construction. Ideally these phantoms will be thermally and temporally stable, and applicable to CD analysis in both sonography and elastography. Several options for combinations of materials for these phantoms are proposed. Construction of test samples is necessary to determine the best set of materials and the longevity and uniformity of the resulting phantoms. Following construction and measuring properties of test samples the best combination of materials will be determined, and CD phantoms will be constructed.
