  • Patent number: 8775199
    Abstract: A method and system to “pump” radiation therapy (RT) images and associated patient information on an Image Guided Radiation Therapy (IGRT) system to a Record and Verify (R&V) system via a standard DICOM connection to allow remote image viewing. Targeted image files in IGRT systems are searched for and transferred automatically. The user identifies the “inlet,” i.e. the source from which the image files are searched, and the “outlet,” i.e., the DICOM server to which the “pumped” imaged are directed. The images can be sent in their original form or fused. The “input” source is scanned periodically at a user-determined time interval. In order not to send the same image multiple time, a time filter skips images generated before a user-selected time and date.
    Type: Grant

  • Patent number: 7349522
    Abstract: A system for dynamic treatment simulation for radiotherapy. Software is implemented on a computer system to perform dynamic simulation by displaying every segment of dynamic treatment beams on top of real-time fluoroscopic image sequences. Automated distortion correction of the fluoroscopic image due to the image intensifier is performed in real-time. A respiration phase indicator measures changes in circumference of the patient's chest through the movement of a radio-opaque marker that appears directly in the fluoroscopic images of the patient.
