The invention relates to a device for the detection of gamma rays coming from a source without image truncation and without image overlapping, comprising, at least, two detection cells and each of said cells comprising a detection space adapted to receive the gamma rays that penetrate through an opening, wherein said detection space comprises one or more detection assemblies, with some of said assemblies being positioned such that they stand in the way of the gamma rays coming into the overlap volume thereof.

Device for the detection of gamma rays with active partitions

An apparatus to detect gamma rays, comprising a scintillator, a position sensitive photo sensor and a scintillation-light-incidence-angle-constraining, SLIAC, element, the scintillator has faces and the position sensitive photo sensor detects scintillation photons exiting a scintillation photons transparent face of the scintillator, and a portion of a scintillator face is covered with an absorbing layer, which absorbs scintillation photons created by scintillation events due to the interaction of incoming gamma rays with the scintillator, and the SLIAC element is optically coupled between a scintillation photons transparent face of the scintillator and the position sensitive photo sensor and the SLIAC element guides the scintillation photons exiting the scintillator towards the position sensitive photo sensor, and the SLIAC element restricts the maximum allowed half light acceptance angle for the scintillation light hitting the position sensitive photo sensor to less than 45&#xb0;.

Gamma ray scintillation detector preserving the original scintillation light distribution

The invention relates to a portable mini gamma camera for intrasurgical use. The inventive camera is based on scintillation crystals and comprises a stand-alone device, i.e. all of the necessary systems have been integrated next to the sensor head and no other system is required. The camera can be hot-swapped to any computer using different types of interface, such as to meet medical grade specifications. The camera can be self-powered, can save energy and enables software and firmware to be updated from the Internet and images to be formed in real time. Any gamma ray detector based on continuous scintillation crystals can be provided with a system for focusing the scintillation light emitted by the gamma ray in order to improve spatial resolution. The invention also relates to novel methods for locating radiation-emitting objects and for measuring physical variables, based on radioactive and laser emission pointers.
