GRID FOR REMOVAL OF SCATTERED X-RAY, AND X-RAY IMAGING SYSTEM USING THE GRID

PROBLEM TO BE SOLVED: To provide a grid for the removal of scattered X-rays, which reduces the effect of a dynamic magnetic field becoming one cause for noise on an image. SOLUTION: For this parallel grid 31 for the removal of scattered X-rays, a grid foil 33, and an intermediate substance 34 are al...

Summary:PROBLEM TO BE SOLVED: To provide a grid for the removal of scattered X-rays, which reduces the effect of a dynamic magnetic field becoming one cause for noise on an image. SOLUTION: For this parallel grid 31 for the removal of scattered X-rays, a grid foil 33, and an intermediate substance 34 are alternatively arranged. In this case, the grid foil 33 comprises lead or the like on both surfaces of which a magnet shielding material 32 comprising ferromagnetic bodies such as Fe, Co and Ni is coated. The intermediate substance 34 comprises Al, organic substances or the like. The magnet shielding material 32 imparts a magnet shielding function to the parallel grid 31 by being coated on the grid foil 33 by laminating.
