Focused Grids
The use of a grid to eliminate scattered radiation is an important way of realising optimum
image quality. The CAWO full metal grids consist of a series of absorbent lead strips interspaced by aluminium strips. Primary radiation passes unhindered between the lead strips, while the scattered
radiation is absorbed by the lead strips.
The number of strips, the relation of the height and distance between the lead strips (ratio) and the interspace medium all determine the quality of the grid. The secondary radiation grids from CAWO are among the best available in the world.
