Model L-661-662 Collimator/Beam Alignment Test Tool

The Ludlum Model L-661-662 Collimator/ Beam Alignment test tool provides the necessary verification of the proper congruence of the collimator light field and the X-ray beam. Misalignment of the collimator may cause key portions of the image to be missing from the radiographic image.

Model L-430, L-431, L-434 HVL Filter Plates

Standard and High Purity HVL Filter Plates are used to determine if there is sufficient inherent filtration in the X-ray beam to remove the damaging lower energy radiation being emitted from the X-ray tube.

Model L-116 CR/DR TG-116 Filter Holder Set

One of the key benefits of Digital Radiography (DR) is the ability to make image quality corrections after the exposure has been made. Image contrast, density, and brightness values are easily controlled at workstation display screens. Initial exposure settings are greatly simplified with DR.

Model L-435 HVL Filter Holder

The new Ludlum L-435 HVL Filter Holder is designed to simplify the routine HVL measurement process. For years the method of attaching the HVL filters to the X-ray collimator involved using quantities of medical/surgical tape. While tape does the job, it also tends to destroy the thinner aluminum filters, particularly the high purity mammography filters.
