Abstract:
To evaluate the usefulness of photon counting X-ray radiography (quantum radiography, QR) for diagnostic imaging of the thorax, comparative studies between QR and the conventional screen-film system (SF) were performed. Exposure dose, spatial resolution and density resolution on QR were evaluated in the experimental study. The ability of QR to describe normal structures and several kinds of abnormal shadows was evaluated in the clinical study. The relative exposure dose of QR was lower than that of SF, while the spatial resolution of QR was slightly inferior to that of SF. However, the density resolution of QR was superior to that of SF. Clinically, QR was superior to SF in the description of normal structures and several kinds of abnormal shadows. In conclusion, it was considered that QR is useful for diagnostic imaging of the thorax.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
