PTW 2D-ARRAY seven29

The PTW 2D-ARRAY seven29 is a two-dimensional detector matrix with 729 ionization chambers for quality assurance in radiotherapy. 
It can replace use of films in many areas on linear accelerators in IMRT plan verification and quality assurance. The device is light, quickly installed and easy to operate.
A patient plan is transmitted to the 2D-ARRAY in IMRT plan verification. The individual fields are radiated in gantry position 0° on the array.
The data can be evaluated immediately by VeriSoft software after the field has been radiated. Various evaluation algorithms are available such as the gamma index algorithm. Recording of measurement values is completely integrated in VeriSoft.

DAVID - a revolutionary in-vivo dosimetry system based on the novel PTW harp chamber

DAVID - Device for Advanced Verification of IMRT Deliveries - was developed in close collaboration with Oldenburg University. The objective in developing this novel measurement system was to provide a precise and reliable instrument for monitoring administered photon beams in IMRT irradiation.  

Substantial demands are made on quality assurance in IMRT (Intensity Modulated Radiation Therapy). Dosimetric checking of patient plans using flat detectors and expanded quality assurance checks on LINAC are customary.

Checking the multi-leaf collimators, which determine field sizes, is especially important.
