Virtual Grid Adapts Contrast on X-rays to Improve Quality of Exams Taken Without a Grid

Images analyzed for scatter effect; automated, selectable grid ratios applied

November 5, 2014 — Fujifilm Medical Systems will introduce a new X-ray image processing tool called Virtual Grid at the Radiological Society of North America (RSNA) in Chicago, Ill. The Virtual Grid intelligently adapts contrast to improve image quality for exams that are taken without a grid.

The Virtual Grid automatically adapts its processing to replicate grid use to reduce degradation of image quality caused by scatter radiation. This new feature analyzes the image for scatter effect based on exam menu and selected parameters and offers automated, selectable grid ratios to further adapt image quality to site preferences.

Physical add-on grids are commonly required for mobile imaging of large anatomy to help focus radiation to reduce scatter and blurring. Virtual grid processing will be a great benefit to technologists for mobile imaging in emergency room (ER), operating room (OR), bedside, wheelchair and other exams where they may not have the optimal grid or any grid on hand. Use of Virtual Grid also eliminates artifacts typical from misalignment of the tube to detector/grid angle.
