The RD/FL Test Tools are used to quickly assess the image quality and performance of diagnostic radiographic and fluoroscopic imaging systems. The ability to measure contrast and resolution in one exposure allows the operator to quickly determine whether or not the system is working correctly.

The Ludlum Model L-644 Grid Alignment Test Kit is designed to confirm that the proper centering and height uniformity of a standard or focused grid is correctly aligned with the central axis of the X-ray beam.
The Fluoroscopic Resolution Test Tools provide a quick general check on image intensifier or digital video system resolution. The test tool is an acrylic plate containing eight groups of copper and brass mesh screening.
The Ludlum Fluoroscopic Beam Alignment device consists of an aluminum plate with four sliding brass strips set in recessed channels. The strips define the border or visible area of the image receptor.
These test patterns are used for spatial resolution measurements. The procedure is very quick, simple and accurate. The test patterns are used to evaluate film screen and digital systems, as well as magnification techniques.
The Model L-006605 Sensi-C Sensitometer is a 21 step (D 0.15 per step), dual spectrum, single sided sensitometer for constancy testing of transparent X-ray films.
The Model L-006614 DensiQuick Densitometer is a calibratable densitometer for single point measurement of optical densities of transparent X-ray films. The unit will measure the standard 21-step wedge densities (D 0.15 per step) and D-min for automatic calculation of relative speed and average gradient.
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.
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.
The primary purpose of the AAPM TG-51 dosimetry protocol is to provide a uniform methodology for a clinical reference dosimetry measurement. Both the photon and electron beams from accelerators need to be within the recommended nominal energies (Beam Quality).
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.
