CT QA phantom for initial calibration as well as follow-up periodical quality check of CT scanners
The phantom can be used for features of CT evaluation, such as high and low contrast resolutions, feed direction and CTDI
Water Equivalent Material, various inserts and empty bottles enable to verify the appropriate Multi-Energy CT settings
The QUART didoCT meter is designed for easy and precise dose-width product measurements. Its innovative detector features ionisation as well as solid-state technology.
The didoCT is also the first pencil chamber meter with the ability to measure HVL directly in the same exposure as the DLP (didoCT+ version).
The didoCT is equipped with a backlit display to assure swift readings even in darkened environments and the dose or DLP rate is refreshed continuously on the display while the measurement is running.
Special Feature - Direct CT-HVL Measurement
The meter‘s HVL feature is designed to easily measure the aluminium equivalent for a wide range of CT imaging equipment. It is calibrated at suitable standard radiation qualities in accordance with the majority of CT scanners used in radiology or radiation therapy
● DLP: 0.2 µGycm - 999 mGycm (Uncertainty: ±5% / Resolution: 0.01 nGycm)
● DLP Rate: 0.25 µGycm/s - 999 mGycm/s (Uncertainty: ±5% over full range / Resolution: 0.1 nGycm/s)
● Exposure Time: 0.5 ms – 300 s (Uncertainty: ± 0.5 ms / Resolution 0.1 ms)
● CT-HVL (didoCT+): 3.0 – 9.0 mm Al (HVL output, Uncertainty: +/- 8% / Resolution: 0.1 mm Al); Internal Filtration 2.8 - 29 mm Al equivalent and corresponding range of 70 - 150 kVp.
The QUART DVTap phantom is designed to be used as a universal tool for 3D imaging equipment including CT applications.
The phantom (combined with QUART's CTtec software) has been endorsed by IAEA, EFOMP and ESTRO as a comprehensive solution for time-efficient CT and CBCT QA procedures.
Only one exposure is required to create a 3D data set containing all required parameters to evaluate image quality.
Automated evaluation through unique QUART QA/QC software.Phantom can be applied for field sizes from 4x4cm to large fields-of-view (FOV). A universal holder or customised phantom holders available for easy and reproducible positioning.
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 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.
