To assess the probability of detection (by interferometric techniques) of illumination by a coherent source, we characterize the lateral coherence of the off-axis aerosol scattered radiation by applying the van Cittert-Zernike theorem. We find that, for 1.061-microm radiation at a target range of 1 km, the scattered radiation beyond 3.5 cm off axis does not display appreciable lateral coherence.

At present, interventional radiology (IVR) tends to involve long procedures (long radiation duration), and physicians are near to the source of scattered radiation. Hence, shielding is critical in protecting physicians from radiation. Protective aprons and additional lead-shielding devices, such as tableside lead drapes, are important means of protecting the physician from scattered radiation. ...

13 Digital breast tomosynthesis (DBT) is a promising technique to overcome the tissue 14 superposition limitations found in planar 2D X-ray mammography. However, as most 15 DBT systems do not employ an anti-scatter grid, the levels of scattered radiation 16 recorded within the image receptor are significantly higher than that observed in planar 17 2D X-ray mammography. Knowledge of this field i...
