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. Three models are offered (see table below), each with different resolutions for standard, medium, and...

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... Read more
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. A plastic overlay prevents any vertical displacement of the brass strips. Holes drilled in half-inch intervals are filled...

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... Read more
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... Read more

The Low Contrast Resolution Plate is a test tool designed to evaluate the resolution of digital radiography systems. A key concern of digital radiography is the visibility of low-contrast anatomy due to the potential loss of detail associated with film digitizers, imaging plates, printers, and digital display monitors....

The Ludlum CR/DR Test Tool is designed for the evaluation of the newer filmless digital CR (Computed Radiography) and DR (Digital Radiography) imaging... Read more
The L-777-Mini CR/DR Test Tool utilizes a variety of testing parameters that track the uniformity, contrast, and resolution of the imaging system. This is done by the imaging of a variety of targets within the tool that provide subjective and precise values that are used to monitor the High Contrast, Low Contrast, Gross... Read more
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... Read more
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 methodology includes the application of a 1 mm thick lead... Read more
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 technologist has... Read more
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. Custom sizes and quantities are available upon... Read more
