Fluoro 4
Leeds Test Objects′ FLUORO-4 phantom is designed to be used to check the image quality performance of digital and conventional fluoroscopy x-ray systems. These tests should be carried out at acceptance to establish a baseline, and on a routine basis, keeping an on-going record of the test results, which will indicate any deterioration in performance.
FLUORO-4 features the following test details:
- Tube axis direction markings
- Limiting spatial resolution (0.6 − 5.0 LP/mm)
- Low contrast resolution details (8 x 10mm diameter details, depths 0.4 − 4.0 mm)
- Dynamic range (17 different thickness Cu steps each with a central 4.0mm diameter detail, depth 2.5 mm)
- kV test-area (Yb 0.78mm)
- Unstructured inner area (centre-marked)
- Radiopaque numbers indicating dynamic range steps
FLUORO-4 should be used with either PMMA/Cu or Al attenuator plates (available separately).
The phantom is supplied in a soft protective carry bag.
Available in 2 Sizes:
FLUORO-4 (200x200mm)
FLUORO-4-L (300x300mm)
Conforms to standards:
- DIN 6868-4
- DIN 6868-150
The Accu-Gold digitizer and sensors are available with the “Accu-Gold” user software that enables simple measurement as well as rich visualization of the captured data.
This high dose rate chamber provides an excellent response at therapy and other high energy, high dose rate applications. The fully guarded chamber is mounted at the end of a 12 m low noise triax cable.
The RC6 is an unsealed cylindrical 6 cm3, general-purpose ion chamber, designed for general purpose x-ray measurements. It has excellent energy response throughout the diagnostic energy and with an appropriate build-up cap(optional), the energy range can be extended to 60Co.
The RC6M is an unsealed parallel plate 6 cm3 ion chamber specifically designed for low-energy x-ray measurements. It has a thin entrance window and is suitable for x-ray energies in the range of 10 to 40 keV.
