Pre-Health (Field Undecided)
In the majority of my work placements I have seen 6MV used for WBRT. In the hospital I was recently in they used 10MV. I thought this was odd as would the skin sparing effect not lead to underdosage of the lateral aspects of brain? what energy do you use in your centres and why?

Also, what is the difference between dose prescribed to midplane and dose prescribe to isocentre? Would a plan that is 10MV with gantry angles posteriorly be likely to be prescribed to isodose? In work experience we dont usually get to attend the planning meetings or meet the ROs so it can be hard to find out these bits of planning info.
