Research Design of Adjustable Collimator for Irradiation Field

The radiation field adjustable collimator is a mechatronics product. The rectangle opening of collimator is mainly composed of four collimation blocks. Every collimation block has 2 degrees of freedom (DOF). And these collimation blocks are arranged stagger from end to end. The X-ray irradiation field is automatically adjusted by vertical and horizontal motors. The irradiation field adjustable collimator can meet the need of X-ray sources for different fields in industrial inspection and industrial CT. The collimation blocks are arranged in the same plane, which has a compact structure and effectively reduces the leakage of stray X-rays.
