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. WebMar 23, 2024 · Sir Godfrey Hounsfield, the co-developer of CT, chose a scale that reflects the four basic x-ray densities in the human body, with the following values: air = -1000 HU (Hounsfield units) fat = -60 to -120 HU water = 0 HU compact bone = +1000 HU WebTechnical uses (e.g. in medical imagingor remote sensingapplications) often require more levels, to make full use of the sensoraccuracy (typically 10 or 12 bits per sample) and to reduce rounding errors in computations. Sixteen bits per sample (65,536 levels) is often a convenient choice for such uses, as computers manage 16-bit wordsefficiently. gran-stratman industries inc

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. Weboutput value exceeds the bounds of the bit depth of the new image. These values are “clipped” to the maximum or minimum pixel value as appropriate. The contrast can be inverted with the use of a LUT. In Figure 5.4, the dashed line represents a LUT that will invert the contrast in the image. Look-up Table - 8 Bit Depth 0 50 100 150 200 250
