Image critique of PA Caldwell view of the skull. How to tell if there is rotation, tilt, and proper chin lift/tuck. How to correct by changing skull position or tube angulation.

Thanks Francisco... just had my laptop crash but hoping to continue soon.

***** I don't like to use AEC for sinuses... the anatomy of interest is very small and contains a lot of air. If you're slightly off-center it will place compact bone over the ion chamber and will increase the technical factors used. I recommend manual technique... technical factors depend on many variables like generator type, film/screen speed or speed class for digital imaging systems, and several other things. I would generally say increase 30-40% from what you would use for your Caldwell view.

I used Camtasia Studio 7 for the screen recording and Photoshop for my added effects (in green). There are tons of free things you can use though. There's a freeware software called Camstudio that provides basic on-screen recording features - takes a little bit to set up though. You can also use picmonkey and/or Skitch for the photoshop effects.

No problem... glad it was helpful!

Very useful thank you. Actually I had the PA caldwell position down. But when it came to TMJ's it was hard for me to know which side TMJ is projected higher or lower depending on tube angle and explanation definitely cleared that riddle for me, thanks!

Great videos Jeremy. Thanks a lot.

Miles C. D. No problem... glad you like them!

Thanks... if you decide to post any, let me know. I'm using Camtasia Studio 7 for these.

At 6 minutes you have drawn, in green, the petrous ridges. Are you sure you have not indicated the lower orbital floor instead? the petrous ridges are part of the temporal bones and in your image are sitting straight up from the "www.xray" text at the bottom of your screen. The rest of your presentation is great, the angling of the beam to show moving the petrous ridges up or down will work even better with the petrous ridges correctly identified. Rik

very informative thank you, it help a lot ...

I am post graduate in oral medicine and radiology.....OPG machine is an ortho pantomograph used in dental radiology

@TopicsInRadiography 10 лет назад

Interesting... I've only ever heard of them referred to as a "panorex". If you're doing cranial work and want to place the petrous ridges in the lower third of the orbits, you'll have to extend the neck a bit because you can't exactly place a tube angle on the OPG machine. Placing the acanthiomeatal line (AML) parallel to the floor when you extend the neck should align the petrous ridges where you need them to meet the Caldwell positioning criteria.

thank you...

@tarigabdulla124 3 года назад

It's very good 👍

@udayginjupalli3696 10 лет назад

defenetly this is a good presentation sir..have small doubt..if i would like to perform caldwell approach on digital OPG machine what are the modifications i should follow?

@TopicsInRadiography 10 лет назад

What is an OPG machine?

@bloodysmiley4989 10 лет назад

thank you sir...do you do other subjects such as CTS, MRI and UTZ? i could really use some of those ....o and special procedures such as barium enema

For sinuses, we want to use a horizontal beam, and tilt the head 15 degree from OML if our bucky does not tilt. But won't that make the image look almost like a modified Waters?

@TopicsInRadiography 10 лет назад

No... the relationship between the part and the tube will not change. Without a horizontal beam, you would have OML perpendicular to image receptor and 15 degree cuadal angle. If you have a horizontal beam, the only difference is you're angling the OML 15 degrees instead of the tube. In a modified waters, the neck is extended more than this... you should still see the petrous ridges in the lower 1/3 of the orbits.
