Method and system for image pumping

摘要

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.

主权项

1. A device for transferring radiation therapy (RT) images and associated data files over a local area network (LAN) from an image-guided radiation therapy (IGRT) system to a record and verify (R&V) system in a radiation therapy clinic, comprising:
a data processing device having set of executable instructions residing thereon, wherein the executable instructions instruct the data processing device to perform the following steps: (a) selecting an IGRT system as a source of files including x-ray and digitally reconstructed radiograph (ORR) images and associated data files; (b) selecting an R&V system as a destination for said images and associated data files; (c) probing for the availability of said IGRT system and said R&V system; (d) determining whether both said IGRT system and said R&V system are available; (e) periodically repeating steps (c) and (d) until both are available; (f) scanning files on said IGRT system source; (g) selecting files from said IGRT system for automatic transmission based on criteria for selecting said images and associated data files from files stored on said IGRT system for transmission to said R&V system; (h) formatting said files for compatibility with the Digital Imaging and Communication in Medicine (DICOM) standard; and (i) transmitting said files over the LAN.
