Mammography ARRT Review questions with correct answers

What target-filtration combination in analog imaging provides the best penetration for dense or thick breast? CORRECT ANSWER-rhodium target with rhodium filtration The material used for the exit port of the mammography tube is necessary because CORRECT ANSWER-regular glass would harden the emerging beam The intensity of the x-ray beam from the cathode side of the tube is generally higher because CORRECT ANSWER-the heel effect causes variation in the intensity of the x-ray beam The design of the lip of the compression paddle (both height and angle along the chest wall) affects all of the following except that it? CORRECT ANSWER-ensures greater compression of the anterior breast tissue The primary goal of compression is to CORRECT ANSWER-allow uniform penetration of structures within the breast What feature of the high-transmission cellular grid allow these grids to maintain equal or less radiation dose to the patient compared with linear grids? CORRECT ANSWER-they have copper as the strips and air as the interspace material
