The role of DR beam limiter

What is the role of the DR beam limiter? The beam limiter uses a lead plate with an adjustable gap to block the unnecessary original emission lines emitted from the window, thereby controlling the size of the beam and changing the actual X-ray irradiation field. The relationship between the focus, the lead plate and the irradiation field A/B=a/b A is the distance from the focus to the lead plate; B is the distance from the focus to the imaging surface; a represents the opening and closing degree of the lead leaves; b represents the size of the irradiation field.
