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 Phantom 2 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.
