摘　　要：目的:分析使用滤线器在股骨颈水平侧位投照中的价值,在普通X线-胶片摄影系统、CR(间接成像)数字化X线摄影系统及DR(直接成像)数字化X线摄影系统的意义。方法:应用普通X线-胶片摄影系统、CR和DR各对10例股骨颈骨折置换术后的患者行股骨颈水平侧位投照,首先使用滤线器投照,然后不使用滤线器投照,比较图像质量的差异。结果:在股骨颈水平侧位投照时,滤线器在普通X线-胶片摄影系统,CR及DR上都能适用,而且使用了滤线器投照的图像比不用滤线器的图像更清晰,对比度更好。结论:在作股骨颈水平侧位的投照时,无论是普通的X线-胶片摄影系统,CR还是DR数字化摄影系统,都需要使用滤线器。Objective：To analysis the value of using the filter line device in the level lateral projection of femoral neck,including the ordinary X-ray film photography system,CR（indirect imaging） digital X-ray photography system and DR（directly imaging） digital X-ray photography system.Methods：30 patients with the replacement after femoral neck fracture were studdied by using ordinary X-ray film photography system（n=10）,CR（n=10） and DR（n=10）.All patients received level lateral projection of the fractured femoral neck.In order to compare the films quality,we examined these patients with the filter line device and without it,respectively.Results：As for the level projection of femoral neck,using filter line device was all suitable for the ordinary line of X-ray photography system,CR and DR.And the good quality and best contrat occurred after applying the filter line.Conclusion：The filter line device should be used for the level projection of femoral neck,regardless of the ordinary X-ray film photography system,CR or DR digital photography system.
