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.

Apparatus for particle therapy verification comprising a collimator with multiple openings

A method for real-time measurement of a local dose received by a region of a target upon bombardment of the target by an incident beam of hadrons generates at least prompt gamma rays and neutrons. The particles emitted by the target are measured by collimating the region of the target and by placing a detector at a distance L from the region of the target to be measured. The detector is linked to a device for particle energy and time-of-flight measurement, in which the number of prompt gamma rays received by the detector is determined by selecting the recorded events, and a two-directional charged-particle detection system, placed in the beam of incident hadrons before the target, is used so as to obtain the transverse position of the incident hadrons in order to provide spatial information about the prompt gamma rays.
