mAs, time factor & radiographic density: kzread.info/dash/bejne/lH2Xq7CTZMmacbw.html

Thank you sooo much for the explanation! It has cleared up my confusion. This is my first semester in the Radiology program and I want to be the best Rad Tech that I can become!

I'm at the end of the first quarter of my rad tech program! Thank you for your videos :)

thank you so much. you should consider teaching when you get older. you are way better at explaining things better than most teachers!

kVp and x-ray Contrast HELP YOU

Great explanation! Thank you so much! 🙏🏽😊

Than Q for your explanation... ✨🤝

Which factors affect on quality of radiograph.

Could you do a video on lateral chest positioning, and how to correct rotation on lateral? just like the PA chest video you did .

Great Video! You explain things very well. At the end of the video you mentioned exposure charts. What is a good exposure chart that covers all body parts?

Heyy, glad to help. The exposure chart I mentioned is provided to the x-ray department

THANK YOU

When a radiography is too white, that means too much contracts right? If so , does that mean we then need to increase the kvp ? Sorry I get it mixed up

@AskTheRadTech

It depends. If you want a low contrast image (for example an abdomen or chest) but there were many shades of bright white and grey and no distinct difference in anatomy then yes, the kVp would need to be increased for more penetrability. However if you want a high contrast image (for example to see boney structures like the hand, foot, ankle etc) you need a fairly lower kVp but an small increase in density (mAs). Both factors do affect the image though. Sometimes both may need to be increased 🤷🏾‍♀️ Once you have good base value exposure chart you'll know which factor may need adjusting due to the size of the part being imaged. I hope this helped 😅

I DONT KNOW IF IM OVERTHINKING, BUT mAs, I DONT GET IT HOW DO I DETERMINE IT, SOME SAY 500 MA XS 1 SEC, BUT I THOGHT MILLI WAS 1000??? HELP PLEASE ANYONE

@AskTheRadTech

You might be overthinking it too much. mAs = mA x time in seconds. If you multiply 500mA x 1sec you'll get 500 mAs. Just make sure that you're multiplying in seconds. If your units are in milli seconds just convert them to seconds first to avoid any confusion. So 100ms for example is really 0.1 seconds.

When the AEC doesn’t work, you have to double the MAs for a chest?

AEC is not the end all be all. If the exposure isn't right I just switch to fixed (normally inputted) exposure factors based on the patient's size.

@@fashnup2date depending on the tube output sometimes you find yourself having to use kVp around 120+ for significantly larger patients. 6.7 mAs already sounds like a lot. Try using the 15% rule in such a case. Increasing the kVp by 15% gives a 2x increase in exposure reaching the detector. Would help the graininess.

you are brilliant ! thanks a lot

My baby had pelvic and hip x rays.. I only know that kv is 40,ma 400..and x ray image is very good.. How can i know mas is high or low for baby?..

@AskTheRadTech

You'll need to know what the time for the exposure was in order to know the mAs. Usually when the mA is higher it's a hopeful sign that the time should be very low which would mean that the overall exposure amount is reasonable

If all x-rays pass it would be white image ma'am..

@AskTheRadTech

2 жыл бұрын

Would you like to explain your point further? X-rays cause a degree of darkening on the film based on mAs used. Objects of high physical density would appear white or brighter as it absorbs the x-rays so less photons will hit the image receptor. There'll only be a totally blank white film if there no exposure.
