So how is this projection produced? In every text book and university course the instruction is to centre on the joint space. The result is an unnecessary primary beam dose to the foot with scatter that degrades the image. The radiographer will then mask the image to show what you show as being the ideal AP ankle. Just do the job properly and only expose what is required. To correct the projection, just push the tube angulation button and angle up so the collimation excludes the foot. Changing the tube angle in this way does not change the geometry of the projection though 75% of radiographers and 5% of radiologists believe that it will. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-mZPD_gLs5Dw.htmlsi=Kv4YILu0HGbErUYv
