  • Patent number: 11974475
    Abstract: A flexible display panel, a display device and a forming method are provided. The flexible display panel includes a display area and a non-display area, where the non-display area includes a bending sub-area and a binding sub-area, and the bending sub-area is configured to bend the binding sub-area to a side away from the display area, the bending sub-area includes a first organic layer, a second organic layer and a metal wiring layer between the first organic layer and the second organic layer arranged on the substrate, the touch wiring layer is electrically connected to the metal wiring layer; in response to the bending sub-area being in a bending state, a vertical distance from a bending neutral layer of the bending sub-area to the metal wiring layer is smaller than a preset distance.

  • Publication number: 20230181930
    Abstract: A method and apparatus for radiation therapy using functional measurements of branching structures. The method includes determining a location of each voxel of a plurality of voxels in a reference frame of a radiation device. The method further includes obtaining measurements that indicate a tissue type at each voxel. The method further includes determining a subset of the voxels based on an anatomical parameter of a respective branching structure of a set of branching structures indicated by the measurements. The method further includes determining a subset of the voxels that enclose an organ-at-risk (OAR) volume. The method further includes determining a value of a utility measure at each voxel. The method further includes determining a series of beam shapes and intensities which minimize a value of an objective function based on a computed dose delivered to each voxel and the utility measure for that voxel summed over all voxels.

  • Publication number: 20210138268
    Abstract: Disclosed embodiments include systems and methods for archiving complete radiation records for transmission and review. In various embodiments, the radiation therapy archiving system miniaturizes some of the essential features of radiation therapy planning systems including radiation therapy data reading and writing capabilities, functionality for representing contoured objects and other radiation therapy specific features, and functionality for viewing radiation therapy plans. Compact radiation therapy datasets generated by the radiation therapy archiving system may accurately represent previous radiation doses administered to a patient. To help patients transition from one radiation therapy clinic to a remote clinic, radiation therapy datasets may be downloaded to a personal computer and transferred a remote treatment planning system to be used during the design phase of ongoing radiation therapy treatments.

  • 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.

  • 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.
