Answer:

Across
4a 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.
6a phosphor layer with a random distribution of phosphor crystals within the active layer. this layer can be used in both _____ and cassette-less systems and is similar to a standard intensifying screen used with film.
8software function maps the gray-scale to the _____ of interest (VOI) in the histogram. This feature provides image brightness that is at a prescribed level over a large range of exposure. With some digital systems the image brightness will be consistent
9processing _____
Down
1an 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.
2the smallest exposure change (signal difference) that can be captured by a detector. Ultimately, contrast resolution is limited by the _____ range and the quantization (number of bits per pixel) of the detector. Increased contrast resolution is consider
3a "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
5structured (_____) phosphor
7the available grayscale for image acquisition and display. Bit depth is equal to 2n, where 'n' is the number of bits. Bit depth cannot be changed after equipment is purchased and is a vendor-specific _____ characteristic (i.e., 8 bits = 256 shades of gra
