Abstract
An assembly for preventing an overdose of a charged particle beam during therapy to a patient includes a pixelated detector apparatus and a controller. The controller includes, for each pixel: a current integrator circuit that converts the local measured current into a total local detected charge integrated from a start time, the integrator circuit outputting an integrator voltage that corresponds to the total local detected charge; and a discriminator circuit that compares the integrator voltage with a reference voltage, the reference voltage corresponding to a maximum acceptable dose for the patient. A logic circuit generates an overdose fault signal if, at any of the pixels, the integrator voltage is higher than the reference voltage.
