| 内容記述 | After connecting a small image-processing system which was developed at Matsumoto Dental College to an 8-bit (256) capacity conventional image scanner, we conducted a basic study on the use of CRT in electronic image archiving of dental radiographs and in diagnosis. We visual it evaluated whether the CRT image quality was adequate for the detection of abnormal trabecular pattern of mandible (lesion) by comparison with the pantomograph using a contrast paper film which is widely used for examination of the jaw and facial region. Forty films for individuals with lesions and 40 films for individuals without lesions, selected by radiologist, was entered into and evaluated with the small image-processing system. The visual evaluation was performed by 2 other dental radiologists and 4 oral surgeons. The accuracy of image reading on the CRT was slightly higher than that obtained with the films. The dental radiologists who selected the films had a slightly different understanding as to the nature of lesions compared to the oral surgeon, observers, and this difference was reflected in their assessments as to the presence or absence of lesions, when the pantomographic image density covers a wide range, it appears to be necessary to set the intensity level of the transmission-type image scanner at 10-bit (1024) or above. | |||||||
