Rad 105 Exam Questions with All Correct Answers

Rad 105 Exam Questions with All Correct Answers Milliamperage and Exposure time (mA and time) - Answer-Name the two primary controlling factors of quantity As the mAs is increased, the quantity of radiation reaching the IR is increased. As the mAs is decreased, the amount of radiation reaching the IR is decreased (Direct relationship, one goes up the other goes up) - Answer-Name the relationship mAs has with the quantity of x-rays produced? overall blackness - Answer-Define Radiographic Density. Milliamperage/second - Answer-What does mAs stand for increasing the kVp increases IR exposure and the density produced on a film image, and decreasing the kVp decreases IR exposure and the density produced on a film image - Answer-Describe the relationship between each of the following influencing factors and density for film-screen imaging: KV as the speed of a film increases, the density produced also increases; as the speed of a film decreases, the density decreases - Answer-Describe the relationship between each of the following influencing factors and density for film-screen imaging: SCREEN SPEED limiting the amount of scatter radiation that reaches the IR improves the quality of the image, density will decrease - Answer-Describe the relationship between each of the following influencing factors and density for film-screen imaging: GRID RATIO decreasing collimation causes more scatter which will increase density and increasing collimation will reduce the amount of scatter and decrease density - Answer-Describe the relationship between each of the following influencing factors and density for film-screen imaging: COLLIMATION (BEAM RESTRICTION OR AREA OF EXPOSURE)
