to form words that match the clues listed below.
| Word | Clue |
|---|---|
| 9 letters | amorphous selenium TFT detectors, the a-Se layer forms a continuous x-ray-sensitive photoconductor that converts x-ray energy directly to charge. This charge can be directly "read out" by the TFT array. A photodiode is not _____ with a-Se detectors. |
| 6 letters | a photgraphic detector. None are in use except for intraoral _____ imaging. |
| 8 letters | a phosphor layer with a random distribution of _____ crystals within the active layer. this layer can be used in both cassette-based and cassette-less systems and is similar to a standard intensifying screen used with film. |
| 5 letters | a "picture element", or pixel, the smallest area represented in a digital image. A digital radiography image consists of a matrix of pixels, which is typically several thousand pixels in each direction |
| 10 letters | an electronic element that converts light into charge. With indirect TFT detectrs this is accomplished by a light-sensitive amorphous silicon photodiode on top of the TFT array. |
| 6 letters | a prcess whereby several flat panel detectors are joined to obtain one larger detector. Tiling results in segments tha have unequal response requiring flat-field correction for flat panel detectors. |
| 5 letters | all images have unwanted fluctuations in brightness that are unrelated to the object being imaged. These are collectively described as image noise. |
