为探索新生儿影象检查优质照片的理想mAs值,比较传统胶片-增感屏法摄影(film-Screen,FS)和荧光板计算机数字成象法摄影(Computed Radio-graphy,CR)两种技术的照片效果,评估CR系统能够减少的X线辐射剂量,作者做了前瞻性动物模型实验研究。拟新生儿模型选择兔,8只平均重3.6kg(2.6～4.6kg),氯胺酮麻醉下摄胸片和骨盆片。使用的设备为Dupont8×10时的胶片-增感屏组合速200,常规冲洗;Philips荧光板计算机数字成象系统,
In order to explore the ideal mAs value of high-quality images of neonatal examination, we compared two traditional techniques, film-screen (FS) and Computed Radio-graphy (CR) The effect of the photo, to assess the CR system can reduce the dose of X-ray radiation, the authors did a prospective animal model experimental study. Rabbits were selected for the neonatal model, with an average weight of 3.6 kg (2.6-4.6 kg) for eight animals and chest and pelvic slices for ketamine anesthesia. Equipment used Dupont 8 × 10 when the film - Sensitivity screen combination speed 200, conventional washing; Philips Fluorescent computer digital imaging system,
