Lowest kvp for digital radiograph
WebConversely, lower mAs creates fewer photons, which will decrease film density, but is helpful when imaging smaller parts. The measurement of kVp is done by kV meter. The quality of X-ray tube depends upon the kV applied across the filament at the target. A slight change in kV affects the image significantly. Web7 aug. 2014 · The 25% rule states that a 25% increase in mA, s, or mAs is required for each centimetre the patient is greater than the ‘average’. 20, 30 This is more of a guideline as it only works for radiographic situations (low kVp with no grid and high kVp with grid) and is an average of values that deviate from this by 2–5% depending on the kVp. 32, 35 …
