This comment has changed the course of my career, I’m a first year radiography student in the UK and will be eternally grateful for seeing this, I’ve watched your beam geometry videos and after a while I get the concept now. Thank you Peter.

@@alexpendleton4565 Thank you. That is wonderful to hear. I have been battling against the profession for 35 years, trying to get them to understand how badly radiography is performed. I turned it into an art form. When I invented 'collimation based positioning' I was at the end of being second year student and having a lot of trouble doing accurate work without mistakes.I found a way to stop the mistakes and inadvertently made me the most skilled radiographer in the world. I closed a learning feedback loop that didn't exist with centering points. My current quest is to cause a global revolution in radiography beginning in India and surrounding countries because their population gets 6-8 times as much radiation as is required. The rest of the world gets about 1.5 to double what is required. Please spread my message to your peers and your old university.

@@thevoiceharmonic I've already started showing my peers and challenging their beliefs of beam geometry. How do you recommend I develop my understanding of collimation based positioning. Do you have any material I can use?

@@alexpendleton4565 I tried to publish a paper after doing a formal survey of 120 radiographers but I found problems with collecting the data - some students I had taught, some qualifieds I had worked with, various people who had seen my presentations at national conferences or seen my videos. One major complication was that there were no previous research or papers I could use because what I did was unique. No one taught me how to do it. The fact that other radiographers didn't understand the geometry didn't arise until 1986 when I was a 5th year qualified when I commented on another qualified who was teaching the Townes projection. The standard for 30 million (approx) previous projections included the face and thyroid in the primary beam. I said I could do the same projection with 4 degrees less angulation so collimation was to the brow line. So my Townes projections had collimation on the bottom of the image. I was probably the only person in the world who did this. My generation were the first to get a diploma and institution based education, so we were allowed to be radical and miss a lot of indoctrination. My first paper at a national conference was in 1988 where the geometry issue was combined with a collection of the errors that appeared in positioning text books. I ended up being a specialist in locum radiographer so I worked in 40 different practices/companies. In my latter years, I used this time to advance quality control analysis. It was important but also, I was in a unique position. The most important part of my positioning method is that every image is an accurate representation of the quality of your prediction. If no collimation appears on an image, it is the position of the receptor that determines what is shown. My technique meant always striving for perfection - learning from mistakes and getting a buzz from perfection. My last 7 years was working for an old friend who co-owned the company and I was able to develop my technique to perfection. I was able to explain every radiograph to most patients and able to boast that no one in the world could have done a better job. 8 years ago I sent an email. of the geometry and its video to 86 people all around Australia who were on all the boards and panels of all the organisations. I could look at the analytics on KZbin. They all looked at it within 2 days. The number of them who shared the video was zero. That is because sharing it means either admitting to being so stupid as to not realise the truth after 4 decades of practice, or knowing the truth and sending the video with a faint implication that the recipient doesn't know the truth. Show your colleagues this knee skyline view that includes gonads in the primary beam all because of the centering point method and poor education. kzbin.infojKEvrFhnpOo?feature=share

No

Most places no longer shield.

Always shield a man

pray for my man gigglers he's down bad
