In this video Brent and Glenn go over the positions for the cervical spine. Leave your questions in the comment section and they'll get back to you with an answer.

Radiology technicians really have it easy today, compared to my experience. Been retired 20 years and I had to produce the same views with almost none of the help provided today!
hello Janice. I totally agree. I began my career in veterinary medicine in 1975, then transitioned to an RT in 1988. A good share of the "art" we used to use is lost forever
We just added videos on the Inverse Square and Direct Square laws, there are some very good shortcuts on them, and they make the math MUCH simpler! Check those out, and let us know if there are other positions or subjects you would like to see!
Please do! Feel free to share as much as you would like. The videos on Inverse and Direct square law have a simplified formula with a some really great short cuts too!
Also, Usually there are built in grooves in the track that click in and “lock” at 40 inches and again at 72 inches from the upright buckey (the board she is standing in front of) since most X-rays are taken at either of those distances. There is also usually a measuring tape built into the x-ray tube housing if you want to measure it manually. When you have the tube facing down (perpendicular to the floor), and you are over the top of the table with the patient laying down on the table, most modern machines will display the distance from the tube to the table (if the table is at its greatest height). really it’s measuring how much you have lowered the tube housing down from its default height of 40ish inches above the table. Or, again, you can use the measuring tape. The machine will also display the angle of the tube relative to the floor, using either a digital readout or a bubble/bead similar to a level used in construction). So when he is changing the angulation to “15 degrees,” his machine is likely displaying 75 degrees or 105 degrees (plus or minus 15 from 90, since he has it angled 90 degrees already to face the wall). Hope this helps lol.

I do all projections at 180cm and never use centring points. Here is my tightly collimated approach. ruclips.net/video/ZcvH11MfgUo/видео.htmlsi=WL0iOcy4eKftxhm1. I let the light be the guide for positioning so I have to predict the anatomy and then see the result on the radiograph. I close a learning feedback loop that gradually develops mastery, whereas the centring point method won't allow that because the radiograph is not judged successful by what you centred on. Memorising that will never make you a master. All I needed to know was the anatomy and the ideal representation of it.
I do get that, and yes, we do need to make adjustments for each persons individual anatomy, and knowledge of that anatomy is very important! However, for those just starting out, the positioning guidelines should be adhered to as they are learning, they can make those additional adjustment as they mature in their skill. Clearly, you have been doing this awhile, me too, and that experience is invaluable! Nice images by the way!

Thank you for your videos. Can you please add ribs ?
Tank you

I get that! I started in 1982, it is very different now.
thank you
Thank YOU
You are welcome, any other positioning you would like to see?

Glen,
Boards can ask about posterior positions.
I’d love to share this positioning to my students.
Please do! Feel free to share as much as you would like. The videos on Inverse and Direct square law have a simplified formula with a some really great short cuts too!
Yes it’s me. I teach in Houston now.
That is awesome! I am sure you are an excellent instructor!!
do you guys know the measurements by eye or does the machine tell you?
By eye
We get very close by eye, but most machines have a built in digital measuring device that tell us.
