Model L-647 RD/FL Contrast/Resolution Test Tool
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 Model L-647 has center quadrants numbered to correspond to the lines of wire mesh per inch (40, 60, 80, and 100). The tool also has four low-contrast targets of varying diameters (2, 4, 6, and 8 mm), a contrast square, two monitor adjustment squares, and a copper attenuator to simulate the attenuation of a small adult.

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.
Model L-051 TG-51 Linac Filter
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).
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-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-006614 Densitometer
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.
Model L-006605 Sensitometer
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.
Model L-501, L-523, L-538 High Resolution Test Patterns
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.
Model L-600 Fluoroscopic Beam Alignment Tool
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.
Model L-601, L-618, L-619 Fluoroscopic Resolution Test Tools
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.
Model L-644 Grid Alignment Test Kit
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.

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.
