Performing lateral radiography of the knee can be challenging for the technologist because of the problem with superimposing the femoral condyles. There is an alternate method of imaging the knee in the lateral position so that the bony structures are projected to better advantage. For this method, the central ray is angled 5 degrees cephalad and the beam is aligned with the long axis of the lower leg.
对技术人员来说，进行膝关节侧位X线摄影可能具有挑战性，因为存在股骨髁重叠的问题。有一种替代方法可用于对处于侧位的膝关节进行成像，从而使骨骼结构能以更好的效果投影显示。对于这种方法，中心线向头侧倾斜5度，并且射线束与小腿的长轴对齐。
