Multileaf collimators (MLC) are an integral component in modern radiotherapy as they shape the X-ray treatment beam and therefore need to be closely controlled. Currently, MLC leaves are calibrated to +/- 1 mm every month, however leaves can drift beyond this during calibration dates and treatment verification only occurs pre-treatment. MAPS are radiation hard in photon and electron irradiation, have high readout speeds and low attenuation which makes them an ideal upstream radiation detector. Here, we report results using the Lassena MAPS, which is 12x14 cm(2), three side buttable and is capa...
