Abstract

Development of a detector case for complete co-registration of images in a non-fiber-based combined near-infrared spectral tomography and digital breast tomosynthesis, required analysis to find materials that could support a breast under full mammographic compression without affecting the x-ray images or the quality of the near infrared measurements. Several possible solutions were considered, and many types of plastics were tested in the development of the detector case. Light channeling within the detector case changed the data obtained in resin and agarose phantoms, lowering recovered absorption values. Additional developments focusing on blocking stray light were successful and permitted a normal subject imaging exam.

摘要

开发一种用于在非纤维基组合近红外光谱断层扫描和数字乳腺断层合成中实现图像完全配准的探测器外壳，需要进行分析以找到能够在全乳腺钼靶压缩下支撑乳房而不影响X射线图像或近红外测量质量的材料。考虑了几种可能的解决方案，并在探测器外壳的开发过程中测试了多种类型的塑料。探测器外壳内的光导改变了在树脂和琼脂糖模型中获得的数据，降低了恢复的吸收值。专注于阻挡杂散光的进一步开发取得了成功，并允许进行正常的受试者成像检查。
