Abstract

The disclosure is related to an apparatus and method for charged hadron therapy verification. The apparatus comprises a collimator comprising a plurality of collimator slabs of a given thickness, spaced apart so as to form an array of mutually slit-shaped openings, configured to be placed at a right angle to the beam line, so as to allow the passage of prompt gammas from the target, the collimator being defined at least by three geometrical parameters being the width and depth of the slit-shaped openings and a fill factor. The disclosure is also related to a method for charged hadron therapy verification with a multi-slit camera.
