The QED™ features a flat design for easy patient placement. It is ideal for treatments where diode placement is normal to the beam. QED's are available in three photon energy ranges, and a single range for all electron energies.
QED Applications
QED diode detectors should be used in situations where the beam is normal or close to normal to the patient skin surface.

QED Energy Ranges

Accuracy

The QED offers exceptional accuracy for a flat diode detector. When tested on top of 6 cm of virtual water, variation in directional response is +/- 0.5% for 30°, and +/- 1.0% for 45° for 6MV beams.

Angular dependence for 6 MV:
