Essay on radiation

The graphs of black body radiation as a function of temperature were generated using an Excel spreadsheet.Typically, a combination of several intensity-modulated fields with different gantry angle directions produces a customized radiation dose distribution that increases the dose to tumor while at the same time minimizing the dose to the nearby normal tissues.The radiation dose is designed to conform to the three-dimensional shape of the treatment target by modulating the intensity of the radiation beam to deliver a higher radiation dose to the tumor while limiting radiation exposure to surrounding normal tissues.For each target (planning target volume PTV), the user enters the plan criteria: minimum dose, maximum dose, and a dose volume histogram (DVH).Advanced treatment planning software has enhanced our ability to modulate radiation dose.They copied the same plan with the wedges removed and a FIF plan was designed.
