Estimates of US radiographic doses are uncertain because not all relevant details, such as number of retakes, were considered (Preston-Martin and Pogoda, 2003).
Low dose radiograph systems provide population-applicable, 'Gold Standard' radiographic approach for measuring spinal segmental posture in healthy individuals.
For subtype M4, number of high-dose procedures appeared positively associated with AML risk (P trend=0.03 based on interview data, Table 3), as did total dose from radiographic procedures (Table 4).
Finally, it is worth noting that computed tomography (CT) is now widely used in place of many radiographic examinations and the dose to the prostate from a CT scan of the pelvic region can be around 20 mGy, which is comparable to the dose to the prostate from a barium enema examination.
The detector has been designed for use in the Low-dose Digital Radiographic Device "Siberia" instead of a multiwire proportional chamber.
Therefore, the ICRP introduced the concept of the 'diagnostic reference level' (DRL), with the objective of providing a reference level for the radiation dose for standard radiographic and CT examinations [5].
For radiographic projections with highly localized dose distributions, such as those common in dentistry, direct comparison of HE and E may not be meaningful, unless both computation algorithms are known.
The device demonstrated good dosimetric capabilities when compared to reference measurements made with ionization chambers and agrees with radiographic film in the steep dose gradient region produced by the collimator edge.
The radiographs were acquired by a single emulsion mammography film; film focus distance 100 cm; tube voltage 50 55 kV according to the radiographic equipment and the exposure dose was 8 mAs.
Subject-specific knee joint models were evaluated by comparing dynamic knee kinematics recorded by a motion capture system (KneeKG™) and optimized with MBO to quasi-static knee kinematics measured by a low-dose, upright, biplanar radiographic imaging system (EOS®).
