摘要
目的:探讨Schick数字化成像系统的临床应用,评价Schick数字化成像系统的成像质量。方法:随机选取Schick数字化成像系统所拍X线根尖片和Kodak根尖胶片各200张,比较其曝光时间和X线垂直角度,对其成像质量进行分级评价。结果:Schick数字化成像系统所拍根尖片成像质量Ⅰ级者为90%,比Kodak根尖胶片高25%;Schick数字化成像系统所拍根尖片成像质量Ⅲ级和Ⅳ级所占比例为5%,与Kodak根尖胶片无明显差别。结论:采用Schick数字化成像系统拍摄根尖片成像质量优良,能较好地满足临床应用要求。
Objective：To explore the clinical application of Schick digital imaging system and evaluate its image quality. Method： 200 images of Kodak periapical films and 200 periapical film images taken by Schick digital imaging system were Randomly selected,the exposure time and x-ray vertical angle were compared,and the image quality was graded and assessed. Result： Grade I of periapical film images taken by Schick digital imaging system was 90 %, which was 25 % higher than Kodak periapical films. Grade III and IV of periapical film images taken by Schick digital imaging system was 5 % ,with no significant difference compared to Kodak periapical films. Conclusion：The periapical film images quality of Schick digital imaging system was fine, and could meet the clinical requirements.
