Witryna21 paź 2004 · IMRT-compensator is generated from the ideal intensity map. For segmental MLC-IMRT treatment a discrete intensity map (right) is converted from the ideal map for MLC segmentation. The discrete “skyscraper” map displayed has 10 intensity levels. In our clinical application five to eight intensity levels are commonly … WitrynaIMRT does not allow us to change the physics of a photon beam. It is not possible to arrive at a conformal dose distribution through a parallel-opposed beam orientation. In general, choosing orientations that do not include opposing beams will increase target conformity since entrance and exit doses are not being summated.

Witryna18 cze 2024 · The researchers generated 60 Co-compensator IMRT plans for five head-and-neck cancer and five gynaecological cancer patients, and compared these to MLC-based plans using a 6 MV linac. Ford noted that the treatment planning process is similar to that for standard IMRT. “Inverse planning is performed and an idealized fluence … Witryna21 paź 2004 · Our experience shows that the compensator-IMRT technique offers robustness, excellent intensity modulation resolution, high treatment delivery … WitrynaIMRT plan compensators.
