| 内容記述 | The image precision of a computed tomograph (CT) installed at our university was evaluated from a dental-clinical viewpoint. The effective slice width and spatial resolution were measured by photographing 0.3mm diameter microspheres. The results, with a set slice width of O.6mm, resnlted in an effective slice width in a helical pitch of 0.75 of 1.3mm and the spatial resolution was 0.64mm. With a slice width of 1.0mm, the effective slice width in a helical pitch of 0.75 was 0.92mm and the spatial resolution was 1.06mm. The following conclusions were obtained : 1. Even when the set slice width is smaller than 1 mm, the effective slice width is not rednced but it is possibile that the smaller width will resnlt in lower precision. 2. With decreasing helical pitch, the difference between the set slice width and the effective slice width decreases. 3. Smaller slice widths, result in better resolution. 4. It was inferred that there is an error of 0.6 - 1 mm in the dimensional precision of the images, which are used clinically in the z axis direction. | |||||
