2D detector array optimized for fast and accurate verification of rotational delivery IMRT beams versus planned data as well as Linac Machine QA.

The MatriXXEvolution consists of 1020 air vented pixel ionization chambers uniformly distributed among an area of 24 x 24cm² at 100 cm SDD.

The distance between the individual detectors is 7.6mm (center to center). The MatriXXEvolution includes a temperature and pressure sensor to perform an automated k(t,p) correction of the chamber signal.

The parallel readout of all 1020 detectors with a minimum sampling frequency of 20 msec enables acquisition of both, individual IMRT segments as well as the total integrated delivered dose.

A gantry angle sensor connected to the device measures the gantry rotation angle directly.
