Abstract:
Objective To explore the photographic parameter for CR image splicing of double total length lower extremities and the evaluation of clinical application. Methods The suitable X-ray exposure conditions for full-leg digital radiograph was chosen according to the application of FCR-5000 CR imaging system and the exposure conditions of CR in osseous system. Results Optimal tube voltage and milliamp-second of parameters for the full-length leg projection was acquired in terms of the distribution of spatial resolution under different parameters of exposure. Conclusion The exposure parameter of CR in full-leg image stitching should be based on the characteristics of CR imaging system and the results of experiment. It is important to choose the most appropriate exposure parameters to ensure image quality and reduce radiation dose on patients to provide veracious image data for clinical application with osteoarthritis of the knee.
