Precision Dosimeter
Quart’s high-precision dosimeters for diagnostic equipment are designed to maximize user convenience.
Leveraging the manufacturer’s specialized expertise and knowledge cultivated over more than 30 years, these dosimeters minimize the need for complex pre-configuration and allow for the measurement of all evaluation parameters required for quality assurance in a single irradiation, thereby reducing the burden of QA/QC operations.
Furthermore, with a focus on design, they feature an easy-to-read display and a compact, lightweight construction, making them easy to transport and manage.
High-Performance Dosimeters for Diagnostic Equipment
■ QUART didoNEO R
A multi-modality dosimeter suitable for general radiography, fluoroscopy, and dental imaging, featuring the most compact, palm-sized design and capable of high-precision dose measurement. It enables the measurement of key evaluation parameters (dose, dose rate, voltage, exposure time, waveform, total filtration, and half-value layer) in a single exposure.
– The most compact multi-parameter sensor
– The smallest multi-base unit among similar dosimeters
– Waveform verification possible on the base unit (also viewable via PC connection)
– Capable of storing up to 20,000 exposure records
– Options available for functional expansion
– Additional features to be added via future upgrades

■ QUART didoEASY R (for general and fluoroscopy)
■ QUART didoEASY M (for mammography)
■ QUART didoEASY MR (for general and mammography)
dido EASY can be used for virtually all modalities, including general radiography, mammography, fluoroscopy, DSA, dental radiography, and dental CT. No presetting is required, enabling simple, high-precision dose measurement. It is ideal for measuring parameters necessary for regular servicing and quality assurance of X-ray equipment. Another key feature is the ability to directly measure the dose-width product (DWP).
– Measures dose, dose rate, and exposure time
– Directly measures DWP (dose-wide product) during panoramic dental imaging
– Compact, lightweight semiconductor sensor
– Simple yet highly accurate dosimeter
– Easy operation with no preset settings(Positioning → Irradiation → Display of measurement values)
– Automatic correction function for all radiation types
– No additional adjustments or correction settings required
– Equipped with a rechargeable battery, enabling approximately 80 hours of continuous use
