Anthropomorphic radiological phantoms are useful in evaluating image quality in mammography by providing realistic detection tasks to the observer. Methods for creating such phantoms, based on original patient mammograms, are described. Photochemical enhancement techniques and application of fractal interpolation methods for improving the fine detail information contained in such phantoms are discussed. Approaches to incorporating additional calibrated test targets within the phantom are also described.
拟人化放射学体模通过向观察者提供逼真的检测任务,在评估乳腺摄影图像质量方面很有用。本文描述了基于原始患者乳腺X线照片创建此类体模的方法。讨论了用于改善此类体模中所含精细细节信息的光化学增强技术和分形插值方法的应用。还描述了在体模中纳入额外校准测试目标的方法。
