Dose fractionation
Dose Fractionation
Dose fractionation (pronunciation: /doʊs frækʃəˈneɪʃən/) is a term used in radiation therapy to describe the method of delivering the total dose of radiation in multiple, small doses over a period of time. This method is used to minimize damage to healthy tissues and maximize the radiation effect on cancer cells.
Etymology
The term 'dose fractionation' is derived from the English words 'dose', which refers to a quantity of a medicine or drug taken or recommended to be taken at a particular time, and 'fractionation', which means the process of dividing or breaking up into constituent parts.
