Reducing the scatter radiation to an IR results in what type of Contrast? {Ans: Higher radiographic Contrast}Does higher KVP result in less absorption and more variation in the intensities exiting the patient (T/F)? {Ans: False}-Using Excessive KVP in Digital imaging can result in what? {Ans: Increased IR exposure Increased scatter reaching the IR Decreased contrast}A device that is placed between the anatomic area of interest and the IR to absorb scatter radiation exiting the patient {Ans: Grid}What are the effects of mAs on a digital image in regards to brightness? {Ans: mAs does not affect brightness in a digital image}What is the relationship between KVP and Subject contrast? {Ans: High kVp creates low subject contrast/ Low kVp creates high subject contrast}
