Technical note: On the impact of the kV imaging configuration on doses from planar images during motion‐synchronized treatments on Radixact®
Autor: Larry A. DeWerd, Wesley S. Culberson, John E. Bayouth, William S. Ferris
Publikováno v: Journal of Applied Clinical Medical Physics
Kilovoltage radiographs are acquired during motion‐synchronized treatments on Radixact to localize the tumor during the treatment. Several previous publications have provided estimates of patient dose from these planar radiographs. However, a recen

Effects of variable‐width jaw motion on beam characteristics for Radixact Synchrony®
Autor: J. Smilowitz, William S. Ferris, John E. Bayouth, Wesley S. Culberson
Publikováno v: Journal of Applied Clinical Medical Physics
Purpose Radixact Synchrony corrects for target motion during treatment by adjusting the jaw and MLC positions in real time. As the jaws move off axis, Synchrony attempts to adjust for a loss in output due to the un‐flattened 6 MV beam by increasing

Autor: William S, Ferris, Edward H, Chao, Jennifer B, Smilowitz, Randall J, Kimple, John E, Bayouth, Wesley S, Culberson
Publikováno v: Journal of Applied Clinical Medical Physics. 23
Tracking systems such as Radixact Synchrony change the planned delivery of radiation during treatment to follow the target. This is typically achieved without considering the location changes of organs at risk (OARs). The goal of this work was to dev
