When correcting a Formerly unsatisfactory graphic, underexposure or overexposure needs to be corrected for by adjusting the mAs when analyzing regions of superior distinction (skeleton) or by changing the kVp when examining parts of minimal distinction (thorax).

A lower kilovoltage/high milliamperage strategy provides a radiograph displaying a substantial diploma of contrast. A higher kilovoltage/small milliamperage strategy produces a radiograph of lower distinction but using a big selection. The former strategy is most fitted for areas of very low distinction, such as the abdomen.

Better kVp approaches are suitable for larger sized and thicker animals with limits. Increasing kV is not a linear perform, and little raises in kVp settings read more might substantially improve the amount of x-rays penetrating the animal. Nevertheless, for numerous factors referring to the manufacturing and absorption of x-rays, this effect is significantly less extraordinary higher than eighty five kVp.
