Computed radiography (CR) technol-ogy also was used in clinical practice beginning in DIGITAL OPTIMUM kVp Universal CR Technique Chart using a standard 2. With digital radiography becoming more common, it may seem less important to have accurate technique charts; however, digital systems still cannot correct for some underexposure and overexposure issues. Digital radiography for dentistry is becoming more popular. Chart proving higher kVp and lower mAs always lowers the dose B. 6 70 2 Chest -Adult AP (400 - tt -72") 85 2 - 2. com Each technique also has the ESE Dose.
