Description

An advantageous radiation modality for treating cancer is hadron therapy, which at present uses protons and carbon ions. However, treatment with hadrons requires high spatial and dosimetric accuracy in order to achieve optimal dose delivery, which is in turn guaranteed by proper quality assurance (QA) procedures and tools. For this purpose, a promising tool is the LaGEMPix detector that combines a triple GEM (Gas Electron Multiplier) with a matrix of organic photodiodes coated on an oxide thin film transistor (TFT) backplane. A first prototype of the LaGEMPix with an active area of 60 x 80 mm2 and pixels of 126 x 126 μm2 has been successfully built and tested with X-rays as a preliminary step towards the development of a 20 x 20 cm2 detector.
