Rotational radiotherapy treatments such as volumetric modulated arc therapy (VMAT) can have superior overall quality while having shorter delivery time with respect to conventional intensity modulated radiotherapy (IMRT). As with conventional treatments, intrafractional tumor motion is a major source of uncertainty in dose application. To ensure full tumor coverage the planning target volume (P...

Optical orthogonal frequency-division multiplexing (OOFDM) signal is sensitive to nonlinear distortions induced by optical modulators. We propose and experimentally demonstrate a digital pre-distortion (DPD) algorithm to linearize the optical modulators including electro-absorption modulated lasers (EML) and Mach-Zehnder modulators (MZM) used in high-speed OOFDM transmitters. By using an adapti...

The purpose of this planning case report is to share the perceived dosimetric benefits of innovative hybrid volumetric modulated arc therapy (h-VMAT) for bilateral breast cancer radiotherapy in two patients with synchronous bilateral breast cancer. Two patients with early bilateral breast cancer after breast conservation surgery and adjuvant chemotherapy were planned for bilateral breast radiot...
