WebAn imaging system can distinguish between multiple densities in the radiographic image. In the case of digital imaging, it depends on the bit-depth of the system. An 8-bit system can show only 256 gray values instead of a 12-bit system, which shows 4096 gray values. WebBit depth is defined as: A. The total number of brightness levels that can be produced by the digital system B. The total line-pairs per cm that can be resolved by the digital system C. The smallest exposure difference that can be detected by the digital system D. The total number of photons striking the digital receptor A.
