The fundamental premise I teach is to get everyone to use the highest kV and lowest mAs possible, thereby creating the lowest dose to the patient. So the first chart you will see has the optimum kV that can be used in digital radiography for both CR and DR. This is true for every vendor except Konica who built their CR system to use 5-10 kV less than everyone else. This means that Konica uses 5-10 kV higher than film-screen and all other vendors use 15-20 kV more than f-s.
Following that are all of the Universal Technique Charts We've created for both CR and DR Facilities. As you will notice, the CR charts have a certain LgM number at the top of each chart. LgM is Agfa's Exposure Index (EI) acronym. You should contact us if you are not familiar with Agfa's CR LgM system so we can explain how this system is similar to yours.
There are two sets of DR techniques charts. We have one for Cesium and another for Gadolinium. As they use noticeably different amounts of mAs for each, it was necessary to create both of these charts. Please contact us if you are not certain which type of DR detector you are using at your facility.
We have also included a special set of charts that compare one vendor's EI number to the other. These are for CR systems and the charts are titled "CR EI Comparisons Parts 1 and 2".
All of the Optimum kV, CR and DR technique charts below have been effectively used since 2004. As all Imaging Departments have different standards for mottle, noise and burn, you must check all of your new technique images with your radiologist. Your radiologist always has the final say if an image is diagnostic. Digital Radiography Solutions (DRS) cannot be held responsible for any images taken or passed in your facility.
