Image Production

6. Contrast resolution is _____ related to the bit depth of the pixels in the image.
8. _____ is a square arrangement of pixels in columns and rows.
10. The closer the amplitude of the spatial frequency comes to a flat, the _____ the MTF.
11. Anything that interferes with the formation of the image is _____.
14. Detective Quantum Efficiency (DQE) measures the _____ of a system to convert the x-ray input signal into a useful output image.
16. _____ selenium detectors have the highest DQE because they do not have the light conversion step.
17. Major characteristics of digital image include - Spatial Resolution, Contrast Resolution, Dose Efficiency of Image Receptor, and _____.
18. Digital Imaging systems have a higher DQE than film or screen systems because they have a _____ DQE latitude.
19. Exposure _____ is the range of exposures a digital detector can respond to.
20. Contrast resolution is the ability of the digital system to display subtle changes in shades of gray, _____ contrast = fewer shades of gray between adjacent densities and greater differences between adjacent tissues.
22. _____ is the amount of radiation exposure received by the image receptor, not by the patient.

1. Image _____ is the level of intensity of a digital image on display.
2. The ability of a digital system to respond to and differentiate varying levels of exposure, showing more tissue densities (more shades of gray) is _____.
3. _____ a type of radiographic noise where fewer photos reaching the image receptor will cause undesirable fluctuation in image densities, resulting in images with grainy or sandlike appearances.
4. _____ Transfer Function is the ability of the combined components of an imaging system to accurately reproduce the structural details of an object.
5. The size of the matrix determines the size of the pixel, the larger the matrix, the _____ the pixels.
7. Each pixel contains pieces or “bits” of information, the number of bits within a pixel is known as _____.
9. The size of a pixel is directly related to the amount of spatial resolution, or detail, of the image, the larger the pixel, the _____ the detail.
12. _____ resolution is the ability of the imaging system to demonstrate the small details of an object.
13. _____ is synonymous with the x-ray field, it is the amount of patient tissue included in an image.
15. Failure to properly select the correct detectors could result in either underexposure or _____ to the IR.
21. _____ images are recorded as multiple numeric values and are divided into an array of small elements that can be processed in different ways.
