Webthe tube. Although it does reduce beam quantity, filtration serves only to reduce patient dose by absorbing low-energy photons that do not contribute to image formation. ... Brems radiation photon energy can range from just above 0 to the kVp set at the control panel up to 75 keV. 50 keV. 150 keV. Tags: Question 48 . SURVEY . WebPrimarily two types of technology are used to detect a small amount of photons: Photomultiplier – PMT. A photomultiplier typically consists of a photocathode and a downstream secondary electron multiplier in an evacuated (10 -6 ...10 -5 Pa) glass tube. Working principle. The photons encounter a photocathode which, depending on the …
