Photon and Electron Beam in the Treatment of Cancer Patient Based on Monitor Unit Compilation

The aim of this research is to evaluate the precision of the Monitor unit (MU) calculation in radiation therapy to survive the cancerous patient, is the measurement of actual dose required to delivered. An essential key of quality assurance in radiation therapy is verifying the accuracy of monitor unit calculations. Difference between the simpler model calculation and other modifying method calculation assuming a flat water phantom must be required. The accurate measurement of field size is the most important fact since many dosimetric quantities were dependent on field size. Perhaps most commonly used method for determining monitor unit were modified which provide a new formalism.
