The Exposure Index EI (what we will call it from � The Exposure Index now on) number is best if the centering and collimation are very good. EI ranges and corrupted numbers � The concept of Agfa’s CR 1.7 The concept of Agfa’s CR 1.72.3 LgM range, Fuji’s CR 400 CR 400100 S range, GE’s (DR) .2 100 S range, GE’s (DR) .2.6 range and Siemens‘ DR 200 Siemens‘ DR 200900 range. � Even with the range you should always be shooting for the “best” number in that range (which means the lowest dose). These EI numbers are easily corrupted (but but only � These EI numbers are easily corrupted ( up to 100% in most cases). � Lead shields or surgically implanted metal can definitely skew the EI #. � Collimated fields using less than 33% of the IR.

It was just the centering or collimation changes that corrupted the EI number. � Even though the exposure index number (LgM, S and DEI) has been corrupted up to 60%, the image is still perfectly diagnostic/passable in any facility. If your EI number is above 100% over what is � If your EI considered perfect it is not a corruption problem. This means you over This means you over exposed. exposed. What does mAs do in the digital world? � Not what it did in the film world, that’s for sure!! � To a large extent, mAs does not really control brightness (density) any more. � Brightness is almost completely controlled by processing algorithms. � You just need enough mAs or your image will have quantum noise or mottle. 6 11/24/2013 Critiquing digital images Critiquing digital images (continued) � The EI numbers are the number 1 way to critique your image. � Some DR control panels do not have an EI number. You definitely need to use the magnification � You definitely need mode to check for noise and burn. � You should always be able to Level and Window � It is impossible to prove you used the correct technique if all you are using is what the finished image looks like as your gauge. � Witness the awesome power of Automatic Rescaling and make your image look well penetrated and contrasty. contrasty. Fuji 85 kV @ 4 mAs Fuji 85 kV @ 4 mAs S# 357 85 kV @ 8 mAs 85 kV @ 8 mAs S# 171 85 kV @ 32 mAs 85 kV @ 32 mAs S# 38 85 kV @ 200 mAs 85 kV @ 200 mAs S# 6 7 11/24/2013 85 kV @ 400 mAs S# 3 Carestream Portable Detector 85 kV @ 2 mAs EI 1385 85 kV @ 4 mAs EI 1682 85 kV @ 8 mAs EI 1966 85 kV @ 16 mAs EI 2257 85 kV @ 32 mAs EI 2517 8 11/24/2013 85 kV @ 45 mAs EI 2405 What are the differences between CR and DR? � For all CR (except Agfa) you can use at least 50 times too much mAs and have a perfectly diagnostic/passable image. � For most DR you can use about 10 times too much mAs. How can there be a Universal CR/DR technique chart? Merrill’s Atlas of Radiographic Positioning and Procedures � As we all well know, this would have been � In mid 2013 Bruce Long, First Author of impossible in the film/screen processor days. � All modern generators (25 years or newer) are high frequency and all tubes are the same on the inside. � All CR/DR manufacturers set their systems up to have the perfect EI# appear when 1 mR hits the Image Receptor. Is the EI range given by the vendor perfect for your facility? Merrill’s, hired me to create the first ever digital technique charts for the Merrill’s Atlas. � In it’s 50+ year history they have always had film/screen techniques. � In the 14th edition which will be released in 2015, there will be almost 250 digital techniques included (half CR and half DR). � Each technique will also have the ESE Dose. This hip had an LgM of 1.81. The mag view shows that there is acceptable mottle. � My colleague Ramiro and I discovered that we could use half the mAs and still have a perfectly diagnostic image. � Our rads loved the idea of cutting the radiation dose in half (though images had acceptable mottle) mottle) because we’re an Image Gently facility. 9 11/24/2013 This lateral C CSpine also had an LgM of 1.81. The mottle shown is also acceptable.

This is the proof of how much dose you save your patient when you increase the kV and decrease the mAs and/or decrease the EI #. � If you have a diagnostic image and the EI numbers show you can use less mAs, go to the “66% More mAs” chart. � If again you have a diagnostic image and the EI numbers show you can use less mAs, go to the “33% More mAs” chart. � Finally, if you have a diagnostic image and the EI numbers show you can still drop the mAs, go to the “Least mAs” chart.
