STARCHECK 2D Chamber Array
STARCHECK is a precise and reliable tool for fast measurements in radiation therapy beams. Typical applications are quality control and Linac beam adjustment measurements with the detector panel embedded in a solid state phantom. The ionization chambers feature excellent relative response stability, avoiding the need of frequent recalibration Their spatial resolution of only 3 mm ensures precise measurements even in penumbra regions. The scanning lengths covered by 527 detectors distributed 25.2 cm along the principal axes and 34.5 cm along the diagonals. A full set of four profiles is measured in real-time, making STARCHECK useful for start-up behavior checks of the Linac. Additional detectors distributed along the array’s side axis allow checks of MLC leave positions.
The optional FIELDCHECK and BQ-CHECK phantoms extend the scope of the STARCHECK system allowing to measure the congruence of light and radiation field and to check the constancy of the beam quality of high energy photon and electron beams.
STARCHECK maxi has been designed especially for measurements of high-resolution star profiles for radiation fields up to 40 x 40 cm. The higher scanning lengths covered by 707 detectors distributed 40 cm along the principal axes and 56.5 cm along the diagonals are the only difference to STARCHECK. The MR variant STARCHECK maxi MR supports measurements on MR linacs.
All STARCHECK systems are supported by the real time analysis software BeamAdjust and the machine quality control software MultiCheck.
- Bronze / Silver / Gold Service Contracts for STARCHECK systems are available.
