L5 S1 Spot

[@thevoiceharmonic]

It is a projection that is performed poorly. That is because no one seems to bother with postural positioning. Have the patient raise their shoulder and lower the hip they are lying on. That will standardize all your patients. Saying the angle is 3 degrees is a complete guess. It is also a projection directly related to the lateral lumbar spine. Take that first and see how the L5S1 appears and angle the tube. I hope you realize that tube angulation is only collimation. That means centering points are pointless and useless. Why remember 'rules of thumb' when you can actually learn the anatomy? I always use a piece of lead to block 1/3rd of the dose and prevent ovaries from the direct beam.
