EGS (program)
EGS (program)
EGS (program) (pronounced as /iː dʒiː ɛs/) is a medical software program used in the field of Radiology and Medical Imaging. The acronym EGS stands for Electron Gamma Shower, which refers to the process of radiation interaction with matter.
Etymology
The term EGS originates from the words 'Electron', 'Gamma', and 'Shower'. 'Electron' and 'Gamma' are types of Radiation used in medical imaging, while 'Shower' refers to the cascade of particles produced when high-energy particles interact with matter.
Function
EGS (program) is used to simulate the transport of Radiation in matter. It is particularly useful in the field of Medical Physics, where it is used to calculate dose distributions in Radiation Therapy and to simulate imaging systems in Diagnostic Radiology.
