positron-emitting meaning in Chinese
正电子发射
Examples
- The major difference between the two is that instead of a positron - emitting substance , spect uses a radioactive tracer that emits high - energy photons
这两种技术最大的区别在于，单光子发射计算机化成像不用发射正电子的物质，而是用一个能发出高能量光子的有放射性的跟踪剂。 - The basic idea of positron imaging is injected chemical compounds labeled with positron - emitting nuclides into a body , then the distribution of the nuclides from the annihilation of positron and electron can be measured
可见，正电子成像系统的相关研究可由两部分组成：成像装置的研究、图像重建的研究。本论文正是针对这两个方面。
