ARRT Registry Practice Test1 All of the following EXCEPT ___ will result in an increase in AEC response time. a. decreasing the kVp b. Increasing the focal spot size c. increasing the part thickness d. increasing the SID - ANSWER b. increasing the focal spot size Increasing the focal spot size does not change the AEC response time It affects the spatial resolution. Decreasing the kVp increases the exposure time because more photons are absorbed, resulting in fewer...
