Estimating the term…
The invention relates to a PET imaging device for observing the brain, characterised by comprising a structure with a shape that is capable of accommodating a human head, having independent gamma-ray detection modules, said detection modules having continuous scintillation crystals with a polygonal main section, wherein all together the detection modules form a hollow three-dimensional structure that can surround the head, and with said three-dimensional structure being elongated and having a main axis in the direction corresponding to the forehead-nape direction and a shorter axis in the direction corresponding to the straight line joining the ears, and with the adjacent scintillation crystals fitting together laterally in a precise manner along their entire thickness, forming a mosaic-like structure, i.e. without leaving gaps and without overlapping with one another.
A PET imaging device dedicated to the observation of the brain, which has, as a whole, a structure with a shape capable of housing a head, comprising independent gamma ray detection modules, said detection modules comprise continuous scintillation crystals of polygonal main section, in which the detection modules together form a hollow three-dimensional structure capable of circling the head, and said elongated three-dimensional structure having a major axis in the direction corresponding to the front-nape direction and a shorter axis in the direction corresponding to the straight line joining the ears, and the adjacent scintillation crystals being arranged to fit laterally in an exact manner with each other throughout their entire thickness, building a mosaic, that is to say, without leaving gaps and without overlapping each other.
A method for obtaining images with a PET imaging device dedicated to the observation of the brain, which has, as a whole, a structure with a shape capable of housing a head, the method comprising the steps of detecting gamma rays within independent gamma ray detection modules, said detection modules comprise continuous scintillation crystals of polygonal main section, in which the detection modules together form a hollow three-dimensional structure capable of circling the head, and said elongated three-dimensional structure having a major axis in the direction corresponding to the front-nape direction and a shorter axis in the direction corresponding to the straight line joining the ears, and the adjacent scintillation crystals being arranged to fit laterally in an exact manner with each other throughout their entire thickness, building a mosaic, that is to say, without leaving gaps and without overlapping each other.
