LDA-99 SC

1-Dimensional Multi-Detector Array

The LDA-99SC consisting of 99 Hi-pSi diode detectors with just 5 mm spacing between the individual detectors. The LDA-99 SC can be used in water phantom models Blue Phantom2 for fast and accurate commissioning of dynamic and virtual wedges as well as acquisition of standard inplane, crossplane and diagonal beam profiles.

Applications

  • Linac commissioning
  • Dynamic wedges

Furthermore, the LDA-99 SC can also be used for in air QA applications.

The LDA-99 SC is fully integrated into the myQA Accept software.
