In radiation treatment, a cone-beam computed tomography (CBCT) scan is conducted for precise positioning of tumors, and the image quality is usually degraded by motion artifacts due to patient’s respiration and movement during scanning. Four-dimens

In radiography, scattered X-rays cause contrast loss in X-ray images, limiting their clinical usefulness, and are often reduced using several scatter correction methods. One difficulty associated with the existing scatter correction methods is noise

We investigated an efficient method for material decomposition in radiography, which can separate soft tissues and bones from a single radiograph with the aid of a surface image obtained using a three-dimensional laser scanner through which the atten

We investigated a wide image stitching method in digital radiography where an X-ray tube is stationary while a detector moves from one exposure position to the next during acquisition of multiple images of a small field of view. This method completel

Dual-energy radiography (DER) based on basis material decomposition (BMD) is a wellestablished X-ray technique that uses low- and high-kV radiographs to separate soft and dense tissues. Conventional DER methods often lead to reduced image contrast in

In dental computed tomography (DCT), metal artifact reduction (MAR) is a critical issue to improve the clinical usefulness of DCT and remains a challenging problem. Although various MAR methods have been developed in medical CT, those methods may not

In this study, we investigated sparse-view reconstruction in dental computed tomography (DCT) by using a dictionary-learning (DL)-based method to reduce excessive radiation dose to patients. In sparse-view DCT, only a small number (< 100) of projecti
