  • Patent number: 10315048
    Abstract: The present disclosure provides a radiation method for radiating a fluence map having a zero-fluence region under a movement of MLC (Multi-Leaf Collimator) includes a determining step of determining at least one basic fluence map from the fluence map. The basic fluence map includes a first non-zero fluence region and a second non-fluence region having the zero-fluence region therebetween. The radiation method includes a first radiating step including radiating the first non-zero fluence region, along with moving a first group of leaf pairs and moving a vertical jaw to shade the first group of leaf pairs, and a second radiating step including radiating the second non-zero fluence region, along with moving a second group of leaf pairs and withdrawing the vertical jaw to expose the second group of leaf pairs.

  • Publication number: 20170189718
    Abstract: A method for irradiation based on a fluence map includes determining a shield type of each of a plurality of rows of a fluence map. The method also includes determining, for each of the plurality of rows, a movement curve indicating a relationship between an irradiation dose in the each of the plurality of rows and a moving position of a leaf pair corresponding to the each of the plurality of rows. The method further includes determining an initial irradiation dose for each of the movement curves and synchronizing one of the movement curves based on the shield types of the plurality of rows. The method also includes selecting at least one irradiation dose of at least one point on an irradiation dose axis and generating a control point according to the selected irradiation dose.
