目前,腰椎侧位拍片摆位时,因体形的关系,即腰椎长轴线与摄片台不能平行,呈现出腰五端高于腰一端,为纠正不足,常规采用垫高季肋部。使腰一端升高。利用斜射线或将球管向足侧倾斜若干角度的方法投照。前者因物一片距增加,使影像的失真度和模糊度都相对增加。后者出现下段腰椎间隙失真性变窄。用“腰椎侧位投照尺”摆位虽影像很清晰但操作繁锁,使用不方便,尤其在工作繁忙时就更不宜使用。对此,笔者摸索了一种摆位方法,简便、实用、同样能得到很清晰,逼真的影象。方法如下。 患者按常规右侧卧于摄片台上,将高6cm,宽
At present, the lumbar lateral position when filming, because of body shape, that the long axis of the lumbar and the radiograph can not be parallel, showing the lumbar one end of the waist is higher than the waist, to correct the deficiencies, the conventional padded quarter rib. Make the waist one end rise. Projection using the oblique or the ball to the foot side tilted a number of ways to vote. The former due to a piece of space to increase, so that the degree of image distortion and ambiguity are relatively increased. The latter appeared lower distortion of lumbar intervertebral space narrowing. With the “lumbar lateral projection scale” Although the image is very clear but the operation complicated, inconvenient to use, especially in the busy work even more should not be used. In this regard, I explored a positioning method, simple, practical, the same can get a very clear, realistic image. Methods as below. According to conventional patients lying on the right side of the camera stage, will be 6cm high, wide
