We have 2 grades of anti-scatter x-ray grids as below:

1. Aluminum interspaced x-ray grid (called 'conventional grid) has been used for a long time and still mostly installed inside many of x-ray equipment both for analogue and digital application.

2. PET interspaced x-ray grid (called 'low dose grid) is recently developed for fluoroscopy, mobile C-Arm & Mammography application.
As it is produced with PET interspacer, its transmission rate of radiation is significantly higher than conventional grid which means PET interspaced grid is the most helpful tool for making low dose x-ray equipment.
