WitrynaThe effect of radiation technique on survival was examined by comparing outcomes for patients receiving IMRT versus 3D CRT . There were no differences between the groups for age at diagnosis, nor in the proportions of patients who received 50 Gy to the chest wall/breast, a dose to supraclavicular fossa (SCF), or a radiation boost. WitrynaIMRT: A MORE SOPHISTICATED FORM OF THREE-DIMENSIONAL CONVENTIONAL RADIOTHERAPY Two-dimensional (2D) radiotherapy consisted of a single beam from one to four directions. Beam setups were usually quite simple; plans frequently consisted of opposed lateral fields or four-field “boxes” ( Figure 1 ). i of c2h5ohPurpose.
