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 ). WitrynaIMRT sends various doses of radiation toward a tumor across multiple smaller beams instead of using a single radiation beam. This technique allows healthcare providers to direct high doses of radiation toward tumors without exposing the surrounding healthy tissue to harmful amounts of radiation.

Witryna8 mar 2016 · The IMRT plan is optimised in order to achieve increased homogeneity and superior target volume coverage than is achievable with tangent fields alone.
