Abstract [en]

A new electronic portal imaging device, EPID, is under development at the Karolinska Institutet and the Royal Institute of Technology. Due to considerable demands on radiation tolerance in the radiotherapy environment, a dedicated electronic readout system has been designed. The most interesting aspect of the readout system is that it allows to read out similar to 1000 pixels in parallel, with all electronics placed outside the radiation beam-making the detector more radiation resistant. In this work we are presenting the function of a small prototype (6 x 100 pixels) of the electronic readout board that has been tested. Tests were made with continuous X-rays (10-60 keV) and with alpha particles. The results show that, without using an optimised gas mixture and with an early prototype only, the electronic readout system still works very well.
