WitrynaRequest PDF On Dec 31, 2000, J Ting and others published A comparison between ‘step-and-shoot’ and ‘sliding windows’ leaf sequencing algorithms in IMRT Find, read and cite all the ... WitrynaThe optimizer isn’t necessarily aware of whether the IMRT will be delivered using sliding window or step and shoot. It isn’t until after the optimal fluence is calculated that the leaf motion calculator then tries to produce an actual fluence that is close to the desired optimal fluence.

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). WitrynaIMRT dose plans were inversely-optimized using appropriate constraints with the Helios tool on a Varian Eclipse system. Once the optimal fluences were calculated, different … 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. chinook crash germany 1982
