abstract = "Propagation-based X-ray phase-contrast imaging permits the visualization of tissues that have very similar X-ray absorption properties and may benefit a variety of biomedical imaging applications. Unlike conventional radiographic contrast that is related to the projected absorption properties of tissue, image contrast in phase-contrast radiographs contains contributions from absorption-contrast arid phase-contrast. In this work, we develop a general theoretical framework for assessing the contributions of these contrast mechanisms to signal detectability measures in propagation-based X-ray phase-contrast imaging. Specifically, concepts from signal detection theory are utilized to analyze the contributions of phase- and absorption-contrast to an ideal observer figure of merit for a signal-known-exactly/background-known exactly detection task.",
