This is the mathematical basis of computed tomography and positron emission tomography. 这是计算机层析成像和正电子层析成像的数学基础。
Positron emission tomography ( PET ) is an imaging technique that combines a radioactive tracer with a molecule. 正电子发射(PE)断层成像(PET)是一种结合单一分子放射示踪的成像技术。
Antimatter / matter reactions have practical applications in medical imaging, see Positron emission tomography ( PET ). 反物质/物质反应在医学成像有实际应用,注意正电子放射断层摄影术(PET)。
These findings support several other studies using functional magnetic resonance imaging and positron emission tomography, both of which gauge brain activity by measuring blood flow. 这些发现支持了几种应用功能磁共振成像和正电子放射X断层摄影术的研究(它们通过测量血流来检测大脑活性)。
