Radiation treatment controlling the adverse effects

Koong Lei

In the past few decades, radiation treatment has undergone a number of revolutions, and now, techniques like intensity-modulated radiation therapy make it possible to achieve extremely conformal radiation dose distribution (IMRT). For radiation treatments, more advanced patient localization and beam aiming techniques are required because to the increased dose conformity and steep dose gradients. Internal organ displacement between fractions and internal organ motion inside a fraction are factors affecting the repeatability of target position both during and between successive radiation treatment fraction.
