Abstract
An injection molded anti-scatter grid is fabricated from an engineered thermoplastic to form a focused x-ray absorbent framework defining a plurality of inter-spaces. The engineered thermoplastic has higher yield strength than conventional anti-scatter grid fabrication materials, which produces a structurally rigid grid that renders conventional fiber-like inter-space material unnecessary, and further allows the grid to be flexed in one or more directions to change an effective focal length of the grid. The engineered thermoplastic is loaded with high density particles in order to be x-ray absorbent, while still maintaining desired structural properties.
