While most anti-scatter grids are produced manually, JPI-2100 grids are fabricated based on the semiconductor process. This creates far more uniformity between grid lines than a hand assembled grid. The dose distribution after transmission through a JPI-2100 grid homogeneous. Therefore, its mammography image is much cleaner, with equal exposure across the entire image. At present, JPI provides many manufacturers of mammography systems with JPI-2100, a tribute to its quality in the domestic and international market. JPI-2100 grids consist of a pure carbon and lead alloy. The standard production specifications in use today are 36lp/cm, ratio 4:1, and 41lp/cm, ratio 4:1. JPI-2100 can be customized for higher line frequency grids with much accuracy, such as over 100lp/cm for breast tomosynthesys.
