    摘要： The invention is related to an apparatus and method for charged hadron therapy verification by detecting and/or quantifying prompt gammas produced when irradiating a target (6) with a charged hadron beam. The apparatus comprises a collimator (1) provided with a slit-shaped portion (2) configured to be arranged perpendicularly to the beam line and facing the target, a detection means (3,4) suitable for detecting said prompt gammas and a calculation and representation means. In the apparatus and method of the invention, the slit is configured to allow the passage of prompt gammas emitted from a range of depths in said target (6), said depths being measured in the direction of the charged hadron beam. Furthermore, said detection means is configured to detect prompt gammas emitted from each location within said range, and said calculation and representation means is configured to derive from a detected prompt gamma a value representative of the dose at the location from where said prompt gamma is emitted, and to represent a dose-related distribution for a plurality of locations within said range.

    摘要： A method of aligning the radiation beam in a radiotherapy system comprising a source for producing a beam of radiation and a device for imaging from the beam, both mounted so as to be rotatable about an axis using a fiducial phantom between the source and the device, the method comprising: rotating the beam and device in a trajectory about the axis while obtaining a plurality of images of the fiducial phantom from a plurality of different angles, determining from each image of the fiducial phantom the position of the source at the rotational position the image was obtained, and calculating the centre of rotation of the positions of the source to define the isocentre of the system. The invention enables the alignment of a collimator with the source of radiation, the reduction of asymmetry in beam intensity, and is also applicable to magnetic resonance-guided radiotherapy.
