WitrynaThe implementation of modulated treatment has been approached with various modalities such as static (step and shoot) IMRT, dynamic (sliding window), IMAT, helical (tomotherapy), and rotational (VMAT). A brief outline of some of the approaches was discussed in chapter 4. In this chapter IMRT, IMAT and VMAT will be discussed.

WitrynaOnce the optimal fluences were calculated, different modalities to deliver IMRT were considered: Sliding Window (SW) and Step and Shoot (SS) techniques using a different number of intensity levels to approximate the optimal fluences (e.g. 5, … WitrynaIMRT is an extension of 3D conformal radiation therapy (3DCRT) in which only the beam apertures conform to the projected shape of the target. (1) The delivery of IMRT is possible using a computer-controlled multileaf collimator (MLC). IMRT is most commonly delivered either using the step and shoot (2) or the sliding window (3) method.

Witryna1 paź 2010 · Today IMRT delivery techniques with linear accelerator can be divided into two classes: techniques with fixed gantry, called “step and shoot” (S&S) and “sliding window” (SW), and rotational techniques, called intensity modulated arc therapy (IMAT) and volumetric modulated arc therapy (VMAT).

Witryna18 cze 2015 · IMRT is when the Multileaf Collimator (MLC) is introduced. So you have a step-and-shoot option, where the MLC is static during treatment, and then the sliding window technique where you can move the collimators real time during treatment.
