Introduction: Scatter radiation is one of the major sources of error in nuclear medicine data processing. Different methods of scatter correction have been introduced in order to improve the quality of data. However the best method is to avoid recording of scatter photons in acquisition. The only difference between scattered and non-scattered photons is the energy. Pulse height analyzer i...

A method for evaluating characteristics of the scattered radiation emerging from a plane parallel atmosphere containing large spherical particles is described. In this method, the normalized phase function for scattering is represented as a Fourier series whose maximum required number of terms depends upon the zenith angles of the directions of incident and of scattered radiation. Some results ...

Development of scattered radiation in the geometry of a double phase-conjugate mirror is investigated numerically in the framework of a two-dimensional model that accounts for both diffraction and noncollinearity of the interacting beams. The large-scale structure of the scattered beams is found to be distorted because of the convective flow of energy out of the interaction region. We show that...

to scattered radiation. This technology improves the quality of images taken without an anti-scatter grid at bedside or emergency radiography. Conventionally, grids are commonly used to reduce the influence of scattered radiation. However, due to the positioning difficulties, images are often acquired without a grid for mobile examinations, which results in images with low contrast. Virtual Gri...

The purpose of this narrative review is to describe effective efforts in radiation protection limit scattered exposure terms room analysis and find out the difference effect retaining wall thickness limiting scatter dose.
