Abstract:
The present invention is a device and method for the non-invasive detection of hazardous materials in an aquatic environment, wherein the device comprises a sealed housing, in which there is a fast neutron generator (101) surrounded by α particle detectors (106), and gamma quantum detector (111), wherein the fast neutron generator (101) emits neutrons in the direction of the tested object (107) through the neutron and/or gamma quanta guide (108), and the gamma quanta detector records gamma quanta emitted by the nuclei of the tested object (107) transmitted through neutron and/or gamma quanta guide (110).
Abstract:
The subject of the invention concerns a method for reconstructing multi-tracer metabolic and morphometric images by determining time and three-dimensional spatial coordinates of position of positron-electron annihilation into three gamma quanta, the method comprising the steps of: receiving a plurality of events from positron annihilation centers obtained during measurements conducting by TOF-PET tomography, reconstructing time and spatial coordinates for plurality of events collected in first step, determination of a common plane for gamma quanta originating from positron-electron annihilation, transforming a time and spatial coordinates for gamma quanta to a decay plane determined in the previous step, determining in defined in third step decay plane a time and spatial coordinates for an annihilation place, transforming time and spatial coordinates for an reconstructed annihilation place from decay plane reference frame to the image reference frame. The invention also pertains to the tomography system for multi-tracer metabolic and morphometric imaging of an interior of an examined object.
Abstract:
The subject of the invention is a strip device and method for determining the place and time of the gamma quanta interaction as well as the use of the device for determining the place and time of the gamma quanta interaction in positron emission tomography. More specifically the invention describes a solution which allows the determination of the spatial distribution of concentrations of selected substances in the body and changes of its concentration over time.
