This is due to the horizontal motion of the grid that occurs when “Bucky” is employed. The use of “Bucky” introduces further potential complications that may result in cut-off. This application limit shows the range at which FFD can be adjusted which will limit cut-off to 40% or less. This is a particular risk with parallel girds.Īn application limit is assigned to each grid, according to each grid's individual specifications. With regards to this important characteristic, carbon fiber is used as the cover material for MS X-Ray Grids.Ĭut-off, in which the image becomes dull or blurred towards the edges, occurs when the focal film distance (FFD) is set contrary to the FFD indicated for each grid. The attraction of carbon fiber is its low absorption character. We believe that it is impractical to use carbon fiber as inter-spacer material since it is difficult both to process and to control the uniformity of thickness. ![]() We are often asked about “Carbon Fiber Grids”. Wood was often used as inter-spacer material in the past. MS X-Ray Grids are carefully inspected several times and tested under clinical conditions to ensure precision and quality.Īluminum or fiber resin is mainly used for the inter-spacer synthetic resin is applicable as well. After the ratio is fixed, the board becomes the inner substance of the grid and is then covered and finished. Then the surface of the laminated board is smoothed uniformly and the ratio is fixed. These strips are laminated, baked and solidified. ![]() MS X-Ray Grids use aluminum or fiber strips with a thickness of 0.1 - 0.25 mm as transmitting material and lead strips with a thickness of 0.020 - 0.050 mm as X-ray absorbing material. A grid is composed of high X-ray transmitting material and high X-ray absorbing material, each aligned alternately and regularly.
