Patent number: 12115386Abstract: Disclosed herein are methods for patient setup and patient target region localization for the irradiation of multiple patient target regions in a single treatment session. Virtual localization is a method that can be used to register a patient target region without requiring that the patient is physically moved using the patient platform. Instead, the planned fluence is updated to reflect the current location of the patient target region by selecting a localization reference in the localization image, calculating a localization function based on the localization reference point, and calculating the delivery fluence by convolving the localization function with a shift-invariant firing filter. Mosaic multi-target localization partitions a planned fluence map for multiple patient target regions into sub-regions that can be individually localized.Type: GrantFiled: January 7, 2022Date of Patent: October 15, 2024Assignee: RefleXion Medical, Inc.Inventors: Yevgen Voronenko, Debashish Pal, David Quentin Larkin, George Zdasiuk, Jayakrishnan Janardhanan, Michael Kirk Owens, Peter Demetri Olcott

Publication number: 20240221247Abstract: This application describes a method and system for medical 3D imaging reconstruction based on limited-angle 2D image acquisition, which only requires 30˜50% of the data required by traditional scanner-based 3D reconstruction. This approach significantly reduces the radiation dose requirement and improves clinical efficiency. An example method includes: capturing a plurality of 2-dimensional (2D) projections of a target that cover a limited angle of the target; calibrating the plurality of 2D projections of the target to obtain a plurality of calibrated 2D projections; generating a sinogram based on the plurality of calibrated 2D projections; inputting the sinogram into a dual-domain neural network to obtain a 3D volumetric image of the target that is geometrically corrected and calibrated.Type: ApplicationFiled: December 29, 2023Publication date: July 4, 2024Inventors: Linxi SHI, George ZDASIUK, Shiyu XU
