Embodiments of the present invention provide a phantom and radiation detection system () comprising a vessel for containing a tissue equivalent liquid and adapted to pass a beam of test radiation into the vessel (), a detector () adapted to determine the intensity of the beam of test radiation, the detector () being supported within the vessel () and movable therein along an expected path of the beam of test radiation, wherein the detector () is a 2-dimensional detector adapted to determine the spatial intensity and energy deposition of the beam.

Phantom

Some embodiments of the present invention provide apparatus having a particle beamline for passage of charged particles of radiation therealong, comprising: a first beam tracker structure comprising at least one position sensitive detector (PSD) for determining a location with respect to a cross-sectional area of the beam line at which particles pass through the PSD; energy discrimination apparatus for determining an energy of particles that have passed through the first beam tracker structure; and support means for supporting a subject in a path of a particle along the beamline between the first beam tracker structure and the energy discrimination apparatus, the apparatus being configured to be operated in a selected one of a first mode and a second mode, the apparatus being configured, in the first mode of operation, to control an energy of the beam of charged particles passing through the first beam tracker structure such that a Bragg peak of charged particle absorption is located within the subject, and in the second mode of operation, to control an energy of the beam of charged particles passing through the first beam tracker structure such that a Bragg peak of charged particle absorption is located within the energy discrimination apparatus.

Assembly, apparatus, system and method

Some embodiments of the present invention provide a 2D position-sensitive detector assembly comprising at least three substantially planar detector portions arranged in overlapping relationship as viewed normal to a plane of the detector portions, each detector portion comprising an array of substantially parallel, linear detector elements, the detector elements of respective detector portions being mutually non-parallel, the detector elements each being configured to generate one or more electrical signals in response to interaction of a particle of radiation therewith.

Some embodiments of the present invention provide apparatus for detecting particles of radiation comprising: a plurality of solid state semiconductor detector devices provided at spaced apart locations along a beam axis, the detector devices each being configured to generate an electrical signal indicative of passage of a particle through or absorption of a particle by the device; and at least one absorber portion configured to absorb at least a portion of an energy of a particle, wherein one said at least one absorber portion is provided in a particle path between at least one pair of adjacent detector devices, the apparatus being configured to provide an output signal indicative of the energy of a particle, the output signal provided being dependent on the electrical signals indicative of passage of a particle through or absorption of a particle by the devices.
