Abstract

  • A1. Regarding digital radiographic image:
    • A. True. Detector size is a function of the pixel size times the number of pixels.

    • B. False. Increasing the pixel size decreases the spatial resolution. Smaller pixel will allow detection of finer details.

    • C. True. Bit depth determines the number of bits used to indicate the grey level of a single pixel.

    • D. False. The number of grey level is equivalent to 2 to the power of bit size. For example, 212 = 4096 levels of grey, 29 = 512 levels of grey and 28 = 256 levels of grey.

    • E. False. Lossless compression uses image compression algorithm that allows the original image to be perfectly reconstructed from the compressed data.
