WebA 15% increase in kVp will double the exposure to the image receptor. Therefore, you would have to cut your time in half to compensate. 1/2 of 1/10 is 1/20. ... A = 50 mAs @ 80 kVp; B = 100 mAs @ 70 kVp; C = 99 mAs @ 80 kVp; D = 100 mAs @ 70 kVp. A 200 speed CR imaging plate requires _____ of exposure to produce an optimum quality image. This means that a 15% increase in the kVp will lead an exposure approximately 2 times higher at the image receptor (e.g. the detector or film). ... Then we add 8+4=12, which is 15% of 80. Since 92 is 12 higher than 80 we see that the kVp has been increased by 15%. Therefore, we need to divide the mAs by 2 to … See more Typically the kVp is selected first in an x-ray protocol as it influences the contrast and penetrationof the x-ray beam (i.e. the beam quality). In some scenarios it is desirable to lower the … See more The kVp is a very important technical parameter as it is the most direct way to influence the beam quality on x-ray systems. Changes in the kVp are much more impactful than … See more When you optimized a protocol on your system then keeping the exposure constant at the image receptor is important to maintain … See more The two major components of the 15% Rule are: 1) The number of x-ray photons incident on the patient is approximately ~kVp^2 2) The likelihood of the x-rays to pass through the patient and be measured on the image receptor … See more graphic novel poster
