Abstract

A new cone-beam computed tomography (CBCT) system called FineCube has been developed by Yoshida Dental Mfg. Co., Ltd. This CBCT system for dental use has a unique mechanism with a sliding U-arm, which enables a choice between a higher-resolution image and a wider-area image. This study was performed to evaluate the spatial resolution of the two scanning modes. First, a modulation transfer function (MTF) analysis was performed using the oversampling method. The results indicated that the high-resolution mode showed significantly higher spatial resolution than the wide area mode. Second, the resulting images were assessed after scanning a head computed tomography phantom using the two scanning methods, and profile analysis was performed on the images thus obtained, which confirmed the results of the MTF analysis. The results demonstrated that a shift in the rotation axis of only 146 mm yielded higher spatial resolution.
