CT QA Phantom JCT II
Phantom for acceptance testing and periodic quality control in Computed Tomography, compliant with JIS Z 4923:2015, JIS Z 4752-3-5:2008 / IEC 61223-3-5:2004, and JIS Z 4752-2-6:2012 / IEC 61223-2-6:2006 standards.
It allows evaluation of:
- Slice thickness (axial and helical)
- Spatial and low-contrast resolution
- Image noise
- Uniformity
- Mean Hounsfield Units
Multi Slice CT Phantom MHT
Phantom manufactured from an innovative water-equivalent material, with inserts and empty cavities that allow the insertion of various items to verify Multi-Energy CT configurations. This design simplifies evaluation without the need for custom-made water phantoms and is available in two sizes (TR-I and TR-J).
Parameters evaluated:
- Uniformity
- Signal-to-noise ratio (SNR)
- Image contrast
- Dose Index (CTDI)

QUART didoCT
The QUART didoCT enables fast and accurate measurements of the Dose-Width Product (DWP), integrating both ionization and solid-state technologies. The didoCT is also the first ionization chamber-type detector (Pencil Chamber Meter) that allows direct HVL measurements and DLP without the need for pre-setting (didoCT+ version).
Equipped with a backlit display, it continuously updates the dose or DLP rate during measurement, making it easier to read in dark environments. The device is calibrated for a wide range of CT systems and is compatible with standards used in radiology and radiotherapy.
Key Specifications:
- DLP: 0.2 µGy·cm – 999 mGy·cm (±5%, resolution 0.01 nGy·cm)
- DLP rate: 0.25 µGy·cm/s – 999 mGy·cm/s (±5%, resolution 0.1 nGy·cm/s)
- Exposure time: 0.5 ms – 300 s (±0.5 ms, resolution 0.1 ms)
- CT-HVL (didoCT+): 3.0 – 9.0 mm Al (±8%, resolution 0.1 mm Al), internal filtration 2.8 – 29 mm Al equivalent (70–150 kVp
QUART DVTap
Universal phantom for the evaluation of 3D imaging equipment, including CT and CBCT. Together with the QUART CTtec software, approved by the IAEA, EFOMP, and ESTRO, it enables more efficient quality control procedures.
A single exposure generates a 3D dataset for complete image quality assessment, with automated analysis via QUART QA/QC software. Compatible with fields of view ranging from 4×4 cm up to larger FOVs.
Technical Specifications:
- Spatial resolution and Z-resolution
- Equivalent materials: air, soft tissue, bone
- Test objects: PMMA, air, PVC
- Positioning tools: linear and selective markers
- Size: Ø 16 cm, height 15 cm
- Evaluation of scatter, Nyquist frequency, contrast-to-noise ratio, uniformity, artifacts, and figure of merit (FDM)
QUART Dido DTO
The QUART didoDTO software tool is used to transfer measurement data recorded by Dido dosimeters to a PC. From there, the data can be exported using Excel templates.
QUART didoDTO is available as an optional add-on for users who need more flexibility than a standalone dosimeter. One license can be used on a PC for a pair of EASY / CT / MAS / SVM dosimeters.
General Features:
- Export of all stored parameters to Microsoft Excel templates, designed for ease of use
• Quick and easy registration on the server for end users
QUART Nonius
The QUART Nonius is a precise and easy-to-use measuring instrument, ideal for verifying the dimensions and geometric properties of X-ray fields, including Fan-Beam in CT and Orthopantomography (OPG). Compatible with both digital and conventional systems, it offers 0.1 mm resolution and can also be used in radiotherapy applications.
Technical Highlights:
- Resolution: ±0.1 mm
- Open measurement – no added filtration
- USB connectivity (Plug and Play)
- 40 mm sensor with central radiopaque marker
