WebMar 11, 2024 · Its dose rate at 6 MV can reach 600 UM/min and this reaches up to 1400 UM/min with the 6 MV FFF beam. The remaining geometric and dosimetric properties of the Versa HD accelerator are described elsewhere [32–35]. The beam quality for the 6 MV beam is a tissue phantom ratio (TPR) 20/10 of 0.684 and the TPR 20/10 for the 6 WebSkin Sparing. MV photons do not reach maximum dose at the surface/skin but build-up to a maximum dose. This effect is referred to as skin sparing and is desirable for most photon treatments.. Depth of Maximum Dose (d max). The depth of maximum dose is closely connected to photon energy but also source-to-surface distance, field size and beam profile.
WebUse of FFF beams has expanded rapidly in recent years. Hal-cyonTM’s 6 MV-FFF beam profile and monitor unit (MU) rate are dif-ferent compared to FFF beams produced by the TrueBeam (Varian Medical Systems). Ion recombination correction factors, P ion, are lar-ger for FFF beams compared to flattened beams2 in part due to the
WebJan 8, 2016 · For 10 MV and 10 FFF, leaf transmission was set to 0.00356 and 0.00163 respectively. The interleaf leakage through 9 cm thick tungsten MLCs was measured in another study at 0.4% for 6 MV and 0.5% for 10 MV. 1 Such low MLC leakage is novel for IMRT, for which accurate leaf transmission data are critical. 30 18 MV was modeled with … linear system and signalsWebJan 8, 2016 · The Versa HD is a digital linac capable of delivering 6 MV, 6 MV FFF, 10 MV, 10 MV FFF, and 18 MV photon beams, as well as electron beams of 4, 6, 8, 9, 12, and 15 MeV.
