A new breast phantom has been designed for use in evaluating mammographic system performance. This phantom incorporates simulated calcifications and fibrillar objects in fat, of graded size, to permit measurements of detail visibility. A special methodology has been developed for measuring visible object size to achieve reproducible and clinically relevant results. Materials and construction of the phantom also permit carrying out dosimetry with an appropriate ionization chamber. Dosage and detail visibility measurements are reported for the Xerox 125, Min-R and Xonics systems. In addition to providing information regarding technique and image receptors, these results demonstrate the usefulness of the basic phantom design, and suggest possible improvements.
一种新型乳房体模已被设计用于评估乳腺摄影系统的性能。该体模在脂肪中包含了模拟钙化和不同大小的纤维状物体，以允许对细节可见性进行测量。已开发出一种特殊方法来测量可见物体大小，以获得可重复且与临床相关的结果。体模的材料和构造还允许使用合适的电离室进行剂量测定。报告了施乐125、Min - R和Xonics系统的剂量和细节可见性测量结果。除了提供有关技术和图像接收器的信息外，这些结果还证明了基本体模设计的实用性，并提出了可能的改进建议。
