At 15.26. Central ray skimming the sesamoid bones. Hopefully you know that there is nothing special about the central ray. It is the position of the tube focus that causes the geometry of the projection. Tube angulation is one thing and the geometry of the projection is often another. 75% of qualified radiographers fail the geometry test. ruclips.net/video/QRT7wpOZmko/видео.htmlsi=gS8gxg7r0csXl8wZ The geometry can be exploited to perfect projections like 28.36 lateral standing foot. Central ray to the sole of the foot, then angle up and collimate to the sole of the foot. A perfect representation of foot and the surface it stands on which can't be achieved using the technique shown. I retired after 40 years working for 40 practices. My secret to success was not using any centring points, only accurate collimation. This fixed the predicted outcome with the actual radiograph which does not happen in the conventional approach. I mastered radiography as an art form, always striving for perfection and learning from failure, whereas others only satisfied the criteria while following a formula devised in the 1920s, long before accurate collimation and the risks of radiation were appreciated. Look at my collimation approach to lumbar spines then other videos on my channel. ruclips.net/video/4W1g0UVOGq0/видео.htmlsi=2kxhsXDyyb29gnTC
Thanks Jonah Hill, loved you in super bad
I’m dead as fuck lol
