1-Dimensional Multi-Detector Array
The LDA-99SC consists of 99 Hi-pSi diode detectors with just 5 mm spacing between the individual detectors. The LDA-99SC 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
The LDA-99SC can also be used for in air QA applications.
The LDA-99SC is fully integrated into the myQA Accept software.
