Radiation detection apparatus

A scintillation camera for examination of an object, said scintillation camera comprising:

• a wall positioned adjacent an object receiving chamber for receiving an object to be examined, said wall being of a material that blocks high-energy radiation having a wavelength of X-ray radiation or shorter, and said wall having an opening through which high-energy radiation from the object receiving space is able to pass,
• a monolithic scintillation crystal having an incident side and an opposed rear side, said monolithic scintillation crystal being positioned on a side of said wall facing away from the object receiving space and positioned such that high-energy radiation passing through said opening in said wall is incident on the incident side of said monolithic scintillation crystal, said monolithic scintillation crystal converting said high-energy radiation having a wavelength of X-ray radiation or shorter incident thereon into optical radiation,
• at least one bundle of non-scintillating optical fibres, each of said non-scintillating optical fibres having an end that is joined to said rear side of said monolithic scintillation crystal, wherein all said ends of said optical fibers are aligned so as to each point to said opening in said wall,
• at least one position-sensitive detector that detects the optical radiation emanating from the optical fibres.

A scintillation camera comprising:

• a scintillation material which is capable of converting high-energy radiation incident thereon and having a wavelength of X-ray radiation or shorter into optical radiation,
• at least one position-sensitive detector capable of detecting optical radiation, and
• at least one bundle of light guides which is located in front of the detector,
• Characterized in that the bundle of light guides is located between the detector and the scintillation material.
