Improvement in Image Quality and Workflow of X-Ray Examinations using a New Image Processing Method, “Virtual Grid Technology”

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 Grid calculates the component of the scattered radiation from an image exposed without a grid and improves the contrast and granularity to replicate that of an image exposed with a grid. This technology resolves the problem of artifacts caused by misalignment when using a grid, and enables a more efficient radiographic workflow. This report will describe an outline of Virtual Grid and explain its usefulness by using the experimental results. Abstract
