The QUART Nonius is an easy-to-use and very sophisticated measuring instrument to verify size and geometrical properties of x-ray fields. It can also be used to analyse characteristics of fanned x-ray beams as used in CT or dental panoramic x-ray (OPG).
The QUART Nonius is incredibly flexible and its precision is an absolute strong point – as it achieves a resolution in the socalled nonius range of 0.1 mm.
Recent studies have proven that QUART Nonius can also be used for field measurement in radiation therapy applications.
The QUART didoEASY meters are designed for users who emphasise high precision in dosimetric applications but do not require the performance of a full-range dosemeter package.
QUART didoEASY meters can be used to measure parameters which are essential for service and quality assurance operations at x-ray equipment such as dose, dose rate and exposure time.
Without the need for any pre-setting procedure, measurement results are acquired very quickly.
The QUART didoEASY automatically compensates for most beam qualities. No further corrections or compensations are required.

The QUART didoDTO software tool is used for transferring stored measurement data from dido meters into a PC system. From there, the data can be processed through Excel templates.
QUART didoDTO is available as an optional extra for users who need a bit more flexibility than just a stand-alone meter. One license can be used on one PC for a couple of EASY / CT / MAS / SVM meters.
The QUART didoMAS meters automatically set the range of measurement. No pre-setting is required for direct reading of mA, mAs and time parameters.
The meters can be used throughout the complete range of radiographic equipment including fluoroscopic or mammography exposures.
The meter is powered by a rechargeable battery. One charge is sufficient to last approximately 80 hours of continuous use.
Recharging the meter until full takes only between 3–4 hours. A warning will appear on the display when the battery is running low.
The QUART didoMAS has an extra-long connection cable included in delivery.
The connection between circuit and the detector unit is polarity independent. The mA is refreshed and displayed every second.
The MaVo_lux 5032B light and luminance meter was developed specifically for medical application.
It features luminance and illumination measurement in a single device. Light measurement is performed in Class B mode.
For quality control on x-ray equipment with digital storage screen (CR) or CCD image detectors (DR).
It does not contain planar grid structures, for a better detection of artifacts.
Complies with DIN 6868-13, -58 and -150 as well as IEC 61223-3-1 and -2-11.
The QUART dent/digitest line of phantoms is designed to be used for QA/QC acceptance and routine testing in digital dental x-ray applications ranging from intra-oral, panoramic and cephalometric equipment.
The phantoms comply with IEC 61223-3-4 and IEC 61223-2-7, DIN 6868-151 and DIN 6868-5 as well as IPEM, ÖNORM, PNEN standards and AFSSAPS regulations.
The QUART Pinhole Cameras are test tools designed to be used in conventional as well as digital radiography & fluoroscopy x-ray applications for precise focal spot assessment.
The tools are designed to precisely measure both length and width of the effective focal spot size of x-ray equipment projected down the central ray in the x-ray field.
Set of 440 mm "0" center cross-shaped rulers on a center aluminum pin.
The center is designed to easily read all 20 graduations in all directions from the center, with no graduation overlap.
The base ruler has a built-in stabilizer with clear rubber feet to keep its position on the image receptor.
A set of lines on the base helps the user quickly align the rulers at 90° to each other.
The QUART mam/digi EPQC phantom is designed to be used as a universal tool for QA/QC routine testing in Digital and Analog Mammography. Due to its concept, the phantom creates a link between technical and clinical image quality. It can also be used as QA tool for Digital Tomosynthesis.
Unique in its kind, for the first time the QUART mam/digi phantom incorporates so-called Landolt Ring Structures. Similar to the gold structures of the CDMAM phantom, the Landolt structures are meant to verify low contrast and perceptibility limits. However, the Landolt objects are developed to compare better to the morphology of micro calcifications than any other available structure within current mammography QA/QC phantoms.
Only one exposure is required to collect all necessary parameters to determine the imaging quality of the x-ray system. After the exposure, the image can be visually checked or automatically evaluated through the unique QUART MammoPro software module.
X-Ray Multi-Meter for Service and QA in R&F and Dental
The QUART didoNEO line of meters introduce a new approach to the market of diagnostic x-ray measurement:
Digital Subtraction Angiography QA Test Phantom
The QUART DSA phantom is designed for maximum precision in QA/QC of Digital Subtraction Angiography equipment.
The QUART DSA phantom was designed to obtain maximum accuracy in QA/QC of Digital Subtraction Angiography equipment by simulating the Contrast injection process.
With a Type B sliding design, it allows longitudinal sliding technique to minimize structural motion artifacts in the test image. Through this method it is possible to maximize the performance of the QA/QC, compared to other phantoms available in the market that are more susceptible to exceed the limits of artifacts caused by forced transverse movements.
After simulating the injection process, the QUART DSA immediately reveals the lateral borders of the contrast wedge. The low contrast steps are clearly visible and can be well defined in the test image.
The CompFor MTS is a set of equipment necessary to verify the compression force of the Mammographs, being supplied for this purpose, a foam cube with predefined size and density, electronic scale and measuring tape.
The compression force of mammography systems must be measured regularly in both automatic and manual modes to ensure accuracy and reliability. The recommended compression force can be checked, as well as the maximum force, which must not be exceeded.
Depending on the size of the Mammography platform, the most appropriately sized compressor should be used.
