Unit 2

3. amount of detail in any image
5. grid placed directly on top of cassette
7. main function is to convert sensitized silver halide crystals into black metalic silver
10. unwanted radiographic densities in the form of blemishes arising from improper handling, exposure, processing, or housekeeping
14. type of grid in which strips are placed perpendicular to grid surface
15. rectangular or square table of numbers that represents the pixel intensity to be displayed
16. type of grid in which strips are parallel to each other
17. difference between blacks and whites that a monitor can display
19. grid placed under x-ray table surface
20. number of pixels on a monitor's display
21. loss of radiographic density caused by primary beam being absorbed by lead strips in grid

1. type of grid in which strips are placed with progressively increasing angles to match divergence of the beam
2. image file format that standardizes medical digital images from all imaging modalities and picture archiving and communication systems from different manufactuers
4. type of grid in which two linear grids are placed on top of one another
6. ratio of width to height of the monitor
8. series of thin, linear strips made of alternating radiodense or radiolucent material
9. basic picture element
11. main removes unchanged silver halide crystals from film emulsion, leaving the black metalic silver
12. relationship of height of the lead strips to width between them
13. grid built into the cassette
18. the film's inherent ability to produce shades of gray
