Jason Chia-Hsien Cheng has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Programmable segmented volumetric modulated arc therapy for respiratory coordination
    Patent number: 9737730
    Abstract: The invention designs a segmented short-arc VMAT plan, modified from the original VMAT plan, to fit the breath-hold interval. The modified VMAT of the invention has the advantages of its applicability to different planning systems for variously long arcs and its preprogrammed arc segmentation for summated dose consistency. The present invention provides a method and a system for use in administering radiation therapy to patients using a radiotherapeutic apparatus with gantry rotation, and also meets the requirements for dose planning and accurate delivery, as well as coordinates patient's breath-hold level.

  • Programmable segmented volumetric modulated arc therapy for respiratory coordination
    Patent number: 8858414
    Abstract: The invention designs the segmented short-arc VMAT plan, modified from the original long-arc VMAT, to fit the breath-hold interval. The modified VMAT of the invention has the advantages of its applicability to different planning systems for variously long arcs and its preprogrammed arc segmentation for summated dose consistency. Using segmented short-arc modification from the original long-arc VMAT plan is accurate for dose planning and delivery, as well as tolerable for breath-hold VMAT.
