Hologic mammography filter grid

The x ray grid is an important part in hologic mammography. Because the tissue density is very close, contrast is very important for mammography. The increase of scattering lines will undoubtedly reduce the contrast, so the filter grating becomes a very important link in the whole imaging process.

It is generally used in ordinary X-ray photography and hologic mammography, grid plate. The common filling materials between grids are carbon fiber and aluminum. Its structural characteristics determine: first, the linear filter grid can only filter the scattering lines perpendicular to it, but it does not work for the scattered rays parallel to it; second, the existence of filling materials leads to the reduction of the effective ray passing rate.
For hologic mammography, how to make the filter grid work better becomes the key factor to improve the image contrast and reduce the dose.
Newheek hologic mammography filter grid is divided into a variety of types and models to meet your different needs.
