利用放射性同位素发出的阳电子的国产第一号头部用电子计算机装置,具有世界最高级的解像性能。回旋加速器制作的碳素11、氮素13、酸素15等短寿命的放射性同位素发出的阳电子,一遇电子便会消失,但在那一瞬间,它向正相反方向放射一对伽马射线,因此向血液中注入含有产生阳电子元素的化合物,用电子计算机通过断层像便可观察其在脑中的分布情况。 The use of radioisotope positron-made domestically produced the first head with electronic computer devices, with the world’s most advanced resolution performance. The positive electrons emitted by cyclotron short-lived radioactive isotopes such as carbon 11, nitrogen 13, and acid 15 disappear in the event of an electron, but at that instant it emits a pair of gamma rays in the opposite direction, Therefore, a compound containing a positive-emitting element is injected into the blood and its distribution in the brain can be observed through a tomographic image using a computer.
