Web9 de ago. de 2024 · According to Fauber et al. ( 2011 ), high-kV technique has the potential to substantially reduce patient dose during X-ray examination, regardless of the image receptor type. We expected knowledge of the benefits of high-kV technique to improve compliance with the said technique among radiographers in this region. Web21 de set. de 2011 · Changing the kVp on a unit is directly associated with the overall contrast of an image (referred to as the gray scale of contrast). Some x ray units have a fixed kVp (typically in the range of 65 – 75) and some are changeable (from 50 – 100). For those units with a fixed kVp you will not be able to change this setting on your x ray unit.
