This can either be used to increase the image quality at the same X-ray exposure level, or to lower the patient X-ray dose whilst maintaining the same image quality. Second, it is difficult to manufacture energy-integrating detectors with smaller pixel size than approximately 1×1 mm 2 without compromising dose efficiency. The reason for this ...
Other resolutions: 172 × 240 pixels | 344 × 480 pixels | 644 × 899 pixels. Original file (644 × 899 pixels, file size: 445 KB, MIME type: image/png ) This is a file from the Wikimedia Commons .
These pixel sizes have also resulted in creation of its synonyms high-resolution X-ray tomography, micro-computed tomography (micro-CT or μCT), and similar terms. Sometimes the terms high-resolution computed tomography (HRCT) and micro-CT are differentiated, [ 3 ] but in other cases the term high-resolution micro-CT is used. [ 4 ]
One of the simpler ways of increasing the size, replacing every pixel with a number of pixels of the same color. The resulting image is larger than the original, and preserves all the original detail, but has (possibly undesirable) jaggedness. The diagonal lines of the "W", for example, now show the "stairway" shape characteristic of nearest ...
The following formula gives the number of pixels, horizontally or vertically, given the physical size of a format and the pixels per inch of the output: = Pixels per inch (or pixels per centimetre) describes the detail of an image file when the print size is known. For example, a 100×100 pixel image printed in a 2 inch square has a resolution ...
y' is the calculated UTM northing of the pixel on the map x is the column number of the pixel in the image counting from left y is the row number of the pixel in the image counting from top A or x-scale; dimension of a pixel in map units in x-direction B, D are rotation terms C, F are translation terms: x, y map coordinates of the center of the ...
