A miniaturised X-ray measuring system for dosimetry
The Nomex multimeter, a miniaturised non-invasive measuring system for absolute dosimetry and quality control in X-ray diagnostic radiology, will be demonstrated in several upcoming European medical trade shows*, including Medica in Dusseldorf.
Produced by PTW, the device can be used for radiography, fluoroscopy, dental, dental panoramic, CT and mammography applications. An HVL reading is also available for mammography.
The multimeter measures dose, dose rate, irradiation time, dose per pulse, pulses, tube voltage (kVp), total filtration (TF) and the half value layer (HVL) in one single shot. Additionally, the dose rate and voltage waveform with full 2 kHz can be stored.
With USB connection for a notebook or PC running the Nomex software, no additional accessories, e.g. power supply or display, are needed for its operation. Because the multimeter is independent of orientation, uncomplicated measurement positioning and adjustment are guaranteed, the manufacturer points out.
When radiation is detected, measurements begin automatically. The dose and kV ranges are set fully automatically, thus avoiding multiple exposures.
The software can be operated intuitively and allows most convenient and clear data handling, PTW adds. Statistics functions are provided as well as data export in different formats.
