Kettering - Image Production Questions and Answers | Latest Version | 2024/2025 | 100% Pass What term describes the overall amount of x-rays reaching the image receptor? It's called Receptor Exposure. The main factor that controls Receptor Exposure is what? mAs. What term describes the ability of a radiographic system to record adjacent small structures? Spatial Resolution. The main factor that controls subject contrast in adjacent areas is what? Radiographic Contrast. What is the main factor controlling Radiographic Contrast? kVp. What causes darkening of images due to scatter radiation? Radiographic fog (scatter). Magnification present within a radiographic image is a form of what kind of distortion? Size distortion. Identify the technical term for the area of sharpness in a radiographic image. It's called the Umbra. Identify the technical terms for the area of unsharpness around an image. Blur and Penumbra. What is the relationship between pixel size and spatial resolution? Increasing pixel size leads to a decrease in spatial resolution. Describe the relationship between mAs and receptor exposure. It's direct; an increase in mAs leads to an increase in receptor exposure. What principle describes the reduction in focus size directed toward the image receptor? Line Focus Principle. What term refers to the effective size of the focal spot as the anode angle decreases? Effective focal spot. How is the actual focal spot size measured? It's measured at right angles to the surface of the anode, reflecting the size of the filament used for exposure. What effect do changes in focal spot size have on the photographic aspects of a radiographic image? As focal spot size increases, recorded detail decreases. List three factors contributing to shape distortion in a radiographic image. Tube angulation, part angulation, and IR angulation. What formula is used to calculate a change in technique when compensating for a change in Source-to-Image Receptor Distance (SID)? Exposure maintenance or the direct square law formula (mas1/mas2 = (sid1/sid2)^2).
