Digital radiography is a method of storing data in a computer storage device using linearly arranged sensors instead of film. A similar technique is computed tomography (CT).

A collimator is a device made of materials that shield radiation such as lead or tungsten to limit the direction and diffusion of radiation. This is a mechanism for reducing the radiation dose rate other than the use beam as much as possible. It is used for γ-ray penetration test so that it is irradiated only in the direction necessary for the safe handling test of radiation, and is shielded in other directions. Generally, it is made of tungsten or lead which shields radiation well, but the required thickness and size are different according to γ-ray energy. It is also called a home stall.
