To augment the proton treatment console at Mayo Clinic Rochester with the capability of fluoroscopy-based motion verification and monitoring, I developed computer vision application (Code name: Wukong), based on high-speed acquisition and real-time processing of flat-panel detector (FPD) data streams. Built as a fully DICOM-aware utility, this .NET/C# Windows desktop application is integrated into treatment planning workflow with Varian Eclipse Scripting API. It also provides an optional ability to store live-captured fluoroscopic frames on a HIPAA-compliant scalable storage cloud.
