Web2 mrt. 2024 · KAP represents the total energy incident on the patent. KAP is combined with a coefficient depending on the irradiated portion of the body and protocol (irradiated organs) to estimate effective dose (E). The coefficients range from 0.028 to 0.29 (mSv/Gy∙cm2). They are derived from Monte-Carlo simulations using anthropomorphic digital phantoms. Web2 aug. 2024 · The air gap technique is a radiographic technique that improves image contrast resolution through reducing the amount of scattered radiation that reaches the image detector.
