Bob, awesome video! Very informative with your clear demonstration using a live C-Arm and tissue phantom. Your description as to where scatter goes depending on orientation/angulation of the C-Arm was very informative. Question, the head/foot of the table, would you have any information regarding scattered radiation in those directions?
it depends where you point. If you put on a cranial angle (point tube towards the head) then more radiation scatters towards the foot then the head. If you are on the patients right side and you need to rotate to an RAO or LOA you should rotate the big C so the tube goes away from you, that is the lower dose position. Hope that makes sense and helps.
@@bobgrossman1 thank you for the speedy reply! Taking angulation of the beam into consideration I can definitely positions myself and guide other staffers! Some specifics, straight AP shot into the patient’s lumbar region, zero tilt and zero rotation on the beam. How safe from scatter/exposure is someone standing at the head or foot of the OR table?
Hello Sir Bob it is a very useful educational video, please can you send us your comments as a written documents because I wanted to educate our radiation workers staff in my hospital. Thank you.
+Ruth A. Diaz Ortega Sorry Ruth but I do not have a video on fluoroscopy equipment. I will add that to my to do list. Glad you found some value in this video.
question...is dose badge worn outside of the lead apron or under the lead so it will measure the radiation penetrating thru the apron? just a question..hope to be enlightened...tnx
From Bushong Radiologic Science for Technologists (11th edition) During fluoroscopy, we position our occupational radiation monitor at the collar to estimate dose to the tissues of the head and neck. The tissues of the trunk of the body receive essentially zero dose; the protective apron does what it is designed to do. It has been shown that during fluoroscopy, when a protective apron is worn, exposure to the collar region is approximately 20 times greater than that to the trunk of the body beneath the protective apron. So, if the occupational radiation monitor is worn beneath the protective apron, it will record a falsely low exposure and will not indicate what could be excessive exposure to unprotected body parts.

Thank you.
thats my dad at the beggining! go dad!!!
Hi Bob, do you have a video about the fluoro equipment?

Thanks, I'd really appreciate that.

outside the lead.
why outside? should it be inside? to measure the radiation penetrating the lead?

Bob Grossman I thought scatter was higher underneath the table where higher dose is towards lower part of body.
Where I work we have two..one outside eg on the collar/thyroid shield and one under the lead.
So helpful!
THANKS
Are you a radiologic technologist?
Yes. I became an RT in 2010, an educator in 2012 and a CT Tech in 2017.
I really like your video. Can I make a suggestion?
sure
