| Question | Answer |
| Barium Fluorohalide Bromides | Common phosphor for computed radiography IP |
| Amorphous silicon | Indirect system works as a light detector to capture fluorescent light |
| Image stitching | Algorythms align multiple images into a single image |
| Collimator edge identification | Alorythms designed to detect abrupt edges of exposure and nonexposure |
| Histogram | Corresponds to a predetermined body part before the imaging plate is read |
| Edge enhancement | Usually increases noise and may produce lower quality images |
| Amorphous selenium | Direct system works to collect the charge and transmits it through the TFTs. |
| charge coupled device | Converts visible light into an e- charge; stores it in a sequential pattern |
| TFT (thin film transistor) | Collects the electric charges produced as an array or matrix of pixel elements |
| Photostimulable phosphor imaging plate | Rigid sheet with several layers to record and enhance transmission of image |
| Image blurring | Applied to high noise images to make the sharp edges blur into the background |
| Indirect acquisition system | Uses two part process involving a scintillator and photodetector |
| Fuji computed radiography system | S-values of 150-250 when properly exposed. |
| Image Aquisition | Begins with x-ray exposure to the IP |
| Direct acquisition system | Directly converts incoming x-ray photons to an electrical signal |
| CR artifacts | Classified according to where they occur in the processing sequence |
| Data clipping | CR systems do not send all data acquired to the post-acquisition system |
