Radiation Dosimeter
Quart’s high-precision dosimeters for diagnostic equipment are designed to maximize user convenience.
Leveraging the manufacturer’s expertise and knowledge cultivated over more than 30 years, these devices 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, the design is carefully crafted to be easy to read, compact, and lightweight, making them easy to transport and manage.
Dosimeter for High-Performance Diagnostic Equipment
■ QUART didoNEO R
This multi-modality dosimeter can be used for general radiography, fluoroscopy, and dental imaging.
It features the most compact, palm-sized design available and enables highly accurate dose measurements.
It allows for the measurement of key parameters including 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
- Waveforms can be viewed on the base unit (or via a PC connection)
- Can store up to 20,000 irradiation records
- Options available for expanding functionality
- Additional features will be added via future upgrades

■ QUART didoEASY R (General and fluoroscopy use)
■ QUART didoEASY M (Mammography use)
■ QUART didoEASY MR (General and mammography use)
It can be used with virtually all modalities, including general radiography, mammography, fluoroscopy, DSA, dental radiography, and dental CT.
No prior setup is required, enabling simple and highly accurate dose measurement.
It is ideal for measuring the parameters necessary for the regular servicing and quality assurance of X-ray equipment.
Another key feature is its 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 for all radiation types
- No additional adjustments or correction settings required
- Equipped with a rechargeable battery, enabling approximately 80 hours of continuous use
