positron

po zuh tron

  • n  an elementary particle with positive charge; interaction of a positron and an electron results in annihilation

  • A positron (the antiparticle associated with the electron) can be considered to be an electron going backward in time.
  • Davidson's tools are the new technologies of brain science: quantitative electrophysiology, positron emission tomography and functional magnetic resonance imaging.
  • In medicine, accelerator technology is used in advanced imaging techniques like positron emission tomography for brain scans and in radiotherapy for cancer treatment.
