Formal Components of IMRT Treatment

 Treatment goals - objectives and constraints:  physical (dose, dose-volume).  biological (NTCP,TCP,EUD, P+)  machine limitations  Method for plan evaluation (optimization)

 “ Tools ” :  Physical Model – planning for each type of delivery has a means of decomposing intensity distributions into deliverable elements  Parameters – variables for a given treatment technique (search space)  Constraints – Physical machine limits (e.g. leaf speed, width)  Manage complexity with automation / robotics in delivery
