JPI HEALTHCARE. CO., LTD. Grid-1000 "Box for radiographic Grid-1000(15""x18""(outside 523mmx481mm)"

A component of an x-ray system used in diagnostic x-ray imaging applications, e.g., planar x-ray imaging. It typically consists of a housing containing lead foil strips separated by x-ray transparent spacers. These spacers or "interspaces" are filled with aluminium (Al) or another x-ray transparent (radiolucent) organic compound. Radiographic grids are placed between the x-ray target (patient) and the x-ray film and are used to absorb scatter radiation, and improve radiographic image contrast. It typically comes in two patterns, linear and crossed. Most are focused to a line in space called a convergent line, but can be used over a variable range called the focal distance.
