Attenuation is when the quantity of x rays is reduced by either absorption or scatter as it travels through matter. Absorption is when x ray photons ionize atoms and transfer its energy to electrons (i.e. photoelectric effect). Scattering is when the x ray photons are ejected out of the primary […]
This is the last week of post topics from the review for the hygiene written boards. Today is the inverse square law and how this applies to changing the PID/cone length and exposure settings for a comparable image density. Inverse square law The inverse square law applies to any source […]
Now that we’ve gone over how changing the different settings affect your final image, we will go over how to adjust the settings and produce an image of similar density. First we’ll discuss kilovoltage peak (kVp) and then onto milliampere (mA). Kilovoltage peak (kVp) A few weeks ago we went […]
