Technical and dosimetric aspects of respiratory gating using a pressure‐sensor motion monitoring system

This work introduces a gating technique that uses 4DCT to determine gating parameters and to plan gated treatment, and employs a Siemens linear accelerator to deliver the gated treatment. Because of technology incompatibility, the 4DCT scanner (LightSpeed, GE) and the Siemens accelerator require two different motion‐monitoring systems. The motion monitoring system (AZ‐773V, Anzai Med.) used for the gated delivery utilizes a pressure sensor to...
