Patent number: 11090017Abstract: Methods and systems for medical imaging including synthesizing virtual projections from acquired real projections and generating reconstruction models and images based on the synthesized virtual projections and acquired real projections. For example, first x-ray imaging data is generated from a detected first x-ray emission at a first angular location and second x-ray imaging data is generated from a detected second x-ray emission at a second angular location. Based on at least the first x-ray imaging data and the second x-ray imaging data, third x-ray imaging data for a third angular location relative to the breast may be synthesized. An image of the breast may be displayed or generated from the third x-ray imaging data.Type: GrantFiled: September 11, 2019Date of Patent: August 17, 2021Assignee: Hologic, Inc.Inventors: Yiheng Zhang, Zhenxue Jing, Christopher Ruth

Patent number: 11076820Abstract: A tomosynthesis system has an x-ray source with an addressable array of electron emitting sections on the cathode. The x-ray source moves rotationally about an imaging target, such as a breast. During the rotation, x-rays are emitting from the x-ray source while the x-ray source continues to move. During the emission of x-rays, different subsets of electron-emitting sections of the addressable array are activated to compensate for movement of the x-ray source. By activating the different subsets of electron-emitting sections, an effective focal spot of the x-ray position appears to retain the same shape, size, and position from the perspective of the imaging target, despite movement of the x-ray source itself.Type: GrantFiled: April 21, 2017Date of Patent: August 3, 2021Assignee: Hologic, Inc.Inventors: Andrew P. Smith, John Laviola

Publication number: 20210220522Abstract: Methods and devices for facilitating post-resection tissue formation to accelerate healing are provided. A hydrogel scaffold with encapsulated cells may be prepared. The encapsulated cells may be cells of the patient undergoing the resection that correspond to a type of the tissue resected. The hydrogel scaffold may be integrated with a frame to form an implantable device for insertion into a cavity created by the resection. The hydrogel scaffold and the frame may be bioabsorbable, and the frame may include non-bioabsorbable, radiopaque markers spaced along the frame.
