Scintillation camera with raised edge photomultipliers

A scintillation camera comprising:

• radiation detection means for emitting light in response to radiation absorbed from a source;
• a first plurality of photosensors having end windows disposed at a first distance from the radiation detection means for providing an output in response to said emitted light directed to said end windows;
• at least one raised photosensor disposed at a second, greater distance from the radiation detection means;
• and
• at least one photosensor of the first plurality located adjacent to said raised photosensor also including a side window for receiving light directed thereto from said radiation detection means.

A scintillation camera comprising:

• radiation detection means for emitting light in response to radiation absorbed from a source, the radiation detection means having a light transmitting surface with a predetermined pattern of peaks and valleys for reducing internal reflections and increasing the efficiency of the camera;
• a first plurality of photosensors disposed at a first distance from the radiation detection means and responsive to the radiation detection means for producing an output in response to said emitted light;
• and
• a second plurality of photosensors located proximate at least one edge of the radiation detection means and disposed at a second distance greater than the first distance from the radiation detection means for increasing the field of view of the camera.

A scintillation camera comprising:

• a scintillation material for emitting light in response to radiation absorbed from a source;
• a first plurality of photosensors disposed at a first distance from the scintillation material and responsive to the scintillation material for producing an output in response to said emitted light;
• a second plurality of photosensors located proximate at least one edge of the scintillation material and disposed at a second distance, greater than the first distance from the scintillation material for increasing the field of view of the camera,
• the scintillation material formed in two or more segments defining an interface between adjacent segments;
• and
• means for increasing the surface area of the interface for improving the transmissivity of the interface.

A scintillation camera comprising:

• radiation detection means for emitting light in response to radiation absorbed from a source;
• photosensor means for providing an output in response to the emitted light from the radiation detection means;
• the radiation detection means including a scintillation material formed in two or more adjacent segments defining an interface between each pair of adjacent segments, each segment having a light transmitting surface facing the radiation detection means, the light transmitting surface including a predetermined pattern of ridges and valleys for reducing internal reflections within the scintillation material;
• means for increasing the surface area at the interface for improving the transmissivity of the interface;
• the photosensor means including:
• a first plurality of photosensors disposed at a first distance from the scintillation material, and
• a second plurality of photosensors located proximate at least one edge of the scintillation material and disposed at a second distance, greater than the first distance, for increasing the field of view of the camera.
