DR
| Question | Answer |
|---|---|
| bit depth | the number of bits used for each pixel. this shows the amount of grays in the pixel. ex: 8 bit depth = 2^8, 12 bit depth = 2^12 |
| bit depth controls the | contrast resolution |
| matrix size controls the | spatial resolution |
| pixel size controls the | spatial reolution |
| a larger bit depth means the pixel will be | more gray |
| the detectors smallest capturing unit | DEL |
| how does decreasing fov affect pixel size | it decreases= more spatial resolution |
| primary determinant in spatial resolution in DR | DEL size |
| the distance in millimeters (mm) from the center of one LED pixel to the center of an adjacent one. | pixel pitch |
| a small pixel pitch indicates | higher spatial resolution/sharpness |
| increasing matrix size for the same FOV will ____ the detail | improve |
| at the detector level what controls spatial resolution | del |
| a decreased bit depth will cause | lower contrast resolution |
| what is dynamic range | the range of exposures captured |
| how does DEL size affect spatial resolution | smaller DEL= smaller pixel= higher resolution. |
| scintillator | converts xray photons to light |
| photodiode | converts light to electric charge |
