GRIDS-: They are made of parallel strips of high attenuating material such as lead with an interspace filled with low attenuating material such as carbon fiber or organic spacer. Advantage 1) removes scattered radiation 2) enhance images contrast. 3) increases image details. Disadvantages:- 1) grid line 2) increases patient exposure dose. 3) tube angle limitations. 4) image magnification. Types of grids 1) focused grids (most grids): strips are slightly angled so that they focus in space so must be used at specified focal distances 2) parallel grid: used for short fields or long distances 3) moving grids:- eliminates the fine grid lines that may appear on the image when focused or parallel grids are used; cannot be used for portable films Please like , share & subscribe Share this video with your friends and colleagues...
