Description
The purpose of this study was to examine the appropriate scanning condition for the AUGE SOLIO on the occasion of the clinical use. The left maxillary premolar region of a head phantom was scanned at combinations of tube voltage (85 kV), tube current (4, 6 and 8 mA) and scanning time (17 and 8.5 s) in two field of view sizes (I mode and D mode). The para-sagittal images of the same position were obtained by using multiplanar reconstruction function. We used the image acquired in best quality condition (8 mA/17 s), as the reference. Six dental radiologists observed each image and compared them with the reference image. They subjectively evaluated the quality of sharpness, noise and artifact using a 10 cm visual analog scale. The Steel method was used to determine significant differences. The image at 8 mA/8.5 s showed significantly lower evaluation scores on noise and artifact. In conclusion, the image quality, at 6 mA/17 s, was comparable to the reference image. These results may help in deciding which scanning condition should be adapted for clinical cases.
