摘　　要：目的:探讨大平板多功能数字X射线机在消化系统中的应用价值。方法:利用动态探测器进行胃肠道检查和胆道造影并观察其优缺点。结果:13例消化道癌性病变和15例炎性病变均有明显显示,且黏膜清晰。胆道体层发现2例普通平片未发现的小结石,摄片优良率提高至98%。结论:大尺寸探测器显示范围包括广,数字脉冲透视点片图像清晰,可提高诊断正确率,且辐射剂量有所减少;缺点是患者旋转体位不如遥控摇篮式胃肠机方便。Objective： To evaluate the application value of large flat-panel multifunction digital machine in digestive system. Methods： Exam the gastrointestinal tract and biliary with dynamic detector, and then observe its advantages and disadvantages. Results： All the13 gastrointestinal cancer lesions and 15 inflammatory lesions were shown clearly, including mucosa. Biliary tomography found two small stones, which were undetected by the general X-ray photography. The excellent rate of the photo was improved to 98%. Conclusion： The advantages of the flat panel detector include the wide range of display, clear image of digital pulse fluoroscopy spot film, the improvement of the diagnostic accuracy and the reduction in radiation dose. The disadvantage is that it is more inconvenient than the remote cradle gastrointestinal machine in rotating the position of the patient.
