The Cobia Flex is a straightforward and simple-to-use instrument for checking that the output from an X-ray tube is correct. The measured values can be read directly from the large, easy-to-read display and can also be stored in the device to be read later.
The internal detector can measure dose, dose rate, kV, HVL, TF, and time. External probes can also be connected to make the Cobia Flex suit your specific needs. A built-in mAs is included, but can be deselected if not required.
The Cobia Flex has no position dependence, just place it under the beam and make sure the detector area is irradiated. There is no need to reset the device between your measurements, so you can stay in the control room until all your measurements are made. The practical log function makes it possible for you to read your measurements when you have the time.

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.

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).

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.

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.

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.

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-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.
