The modified Townes projection should be collimated to exclude primary beam exposure to the thyroid. The TMJs should not include exposure to the entire head, neck and shoulders. It is a pity you don't show the proper collimation on your video as students will think you show the correct approach. Collimation should be 8x8cm for the modified laterals
This presentation was created for a class to prepare students for the ARRT Registry examination. All guidelines provided in this video were based on textbook information and in accordance with test preparation material. Outside of that context, I agree with you on the emphasis placed on collimation to the anatomy of interest. It seems the textbooks have changed recently in regards to prescribed field of view, which is disappointing, but I also make a point to discuss "real world" vs. "exam" during labs and variations in expectations based on radiologist's feedback, department protocol, and of course, principles of ALARA. Hoping students carry that information with them beyond the exams!
@@thestoragepapers I get the same response from all the video tutors. For some reason there is no incentive to teach students how to do the job in the best possible way with the lowest possible dose. Part of the problem is that positioning methods were developed in 1920s long before the light beam diaphragm was invented. The centring point method is deeply flawed and prevents practitioners from mastering the art. Instead, people churn out the same high dose and low quality work. See if you pass this test. Don't be surprised if you don't as 75% of qualified, 95% of students, 90% of the general public and 5% of radiologists fail. All three university tutors I have tested have failed. Unfortunately, that also means no radiographer is game enough or responsible enough to spread the word and this video. ua-cam.com/video/mZPD_gLs5Dw/v-deo.html I presented papers at the 1988 and 2014 at Australian national conferences but nothing has changed apart from universities using my videos and subsequently churning out students who fail to apply the principles because they need to pass uni tests
tbh i think students are more focused on memorizing the positioning along with the 3 different CR angles. Obviously you should collimate and sheild and ask about pregnancy, that's for every exam. I think excluding it in this video is fine. You gonna tell them to confirm name and birthday too? No, its a given.
@@digestingbutterflies612 Have you ever collimated a Townes projection properly? I don't know anyone and I have worked with 300 radiographers in 40 years and presented papers at national conferences in Australia about the issue of no one being taught the geometry of a projection. I figured out a better system for doing radiography in 1978 when I was a student. That meant I didn't have to memorise any centring points for the 140 projections we needed to know. Please watch my videos on how to do the best radiography with the lowest possible dose but begin with this one on the geometry of a projection and use of a focused grid. ua-cam.com/video/mZPD_gLs5Dw/v-deo.html.
It's Tom Colo from Mesa. Thank you for videos, they are fantastic!!! They have saved my Backside more times than I can count!!!
Thanks Tom!
Well done professor. Thank you
It's Great 👍
Thank you ❤
