Paper Abstract

Digital breast tomosynthesis has become accepted in clinical use. It is important to physically evaluate a system to ensure that it is working at full performance. Non-linear reconstruction processing is proposed to improve interpretation of clinical images by enhancing the minute contrasts of breast tissue while suppressing metal artifacts. Because existing measuring methods assume a linear system, physical evaluation applied to images reconstructed with non-linear processing may result in unnatural values. We investigated the influence of different reconstruction methods on physical evaluations. We suggest using images reconstructed by back projection processing without a filter to ensure the device performance directly.
