A measurement technique has been developed for application in the area of noninvasive breast cancer detection. The measurement process involves the use of close-range stereophotogrammetry as a data acquisition device necessary for determination of breast volume and volume distribution. This report details the methodology used to acquire and analyze stereopair photographs necessary to document the validity and reliability of this application. The volume of a test object was determined by both water displacement and stereophotogrammetric analysis to estimate the precision of the proposed methodology. Additionally, the reliability component of the study was documented by analyzing variability of coordinates representing a series of locations marked on the surface of an irregularly shaped object. Both tests confirm that this stereometric analysis is a reliable and valid method of measurement and may be well suited for further development in the field of breast cancer detection.
一种测量技术已被开发出来，用于无创乳腺癌检测领域。测量过程涉及使用近景立体摄影测量法作为确定乳房体积和体积分布所需的数据采集设备。本报告详细介绍了用于获取和分析立体图像对的方法，这些图像对是记录该应用的有效性和可靠性所必需的。通过排水法和立体摄影测量分析来确定测试对象的体积，以估计所提出方法的精度。此外，通过分析代表不规则形状物体表面一系列标记位置的坐标的变异性，记录了该研究的可靠性部分。两项测试均证实，这种立体测量分析是一种可靠且有效的测量方法，可能非常适合在乳腺癌检测领域进一步发展。
