Various Measuring Instruments
Quart’s X-ray field measurement devices and high-precision voltmeters and ammeters are designed to allow for simple operation without requiring any effort on the part of the operator.
They can be used without the need for cumbersome or complex preliminary settings, and provide highly accurate measurement results.
X-ray Field & Fan Beam Measuring Device
■ QUART nonius
This is a measuring instrument designed to easily verify X-ray fields and the geometric characteristics of X-rays.
The nonius is highly adaptable, compatible with both analog and digital systems, and can be used to analyze the fan-beam characteristics of X-rays in CT and dental equipment.
As its name suggests, it features exceptional precision, capable of measuring down to 0.1 mm.
Due to this accuracy, recent studies have demonstrated that it can also be used for measuring X-ray fields in radiation therapy.
The included software clearly visualizes measurement results and is compatible with nearly all PCs running Windows OS. Furthermore, it supports serial imaging, enabling measurements such as displacement in tomosynthesis and CT scans.
[Instructions] Operating the Quart Nonius is very simple.
1. Connect the Nonius to a laptop or tablet (Windows OS) via USB.
2. Place the head unit at the measurement location.
3. Use the irradiation field or a reference point to adjust the position.
4. Irradiate.
5. The measurement results will be displayed immediately.
- Includes Nonius software, a USB cable, and a compact carrying case
- We offer an optional bridge holder that makes it easy to secure the sensor
