A kind of detector for nuclear medicineTechnical field
The present invention relates to technical field of medical instruments, particularly relate to a kind of detector for nuclear medicine.
Background technology
Nuclear medicine diagnostic apparatus is configured to only rebuild the faultage image of subject when utilizing two detectors to be detected simultaneously by two gamma-rays produced because of flooding of positron (Positron).Specifically, subject is made to take in the radiopharmaceutical agent containing positron nuclide.Utilize and include that being detected the antithesis from the 511keV of the subject releasing having taken in this medicine by the detector of multiple detector element groups being such as made up of flasher buries in oblivion gamma-rays.And, utilize two detectors detect within certain period gamma-ray in the case of, gamma-rays detected as " simultaneously ", be counted as a pair antithesis and bury in oblivion gamma-rays.And, antithesis is buried in oblivion gamma-ray generation position specific link detect that antithesis is buried in oblivion on the straight line of gamma-ray two detectors.By accumulation such while count information and carry out reconstruction process, it is thus achieved that positron nuclide distributed image, i.e. faultage image.
Existing nuclear medicine diagnostic apparatus, when detecting the excrescences such as breast, needs a corpse or other object for laboratory examination and chemical testing is inserted into opening part.And breast carcinoma mostly occurs at the root of breast of subject, namely near the thoracic wall of subject.Existing detection breast is difficult to root be detected, if it is desired to detection, needs firmly extruding, can cause the problems such as pain to patient.Result can be impacted simultaneously.
