Patent number: 11786186Abstract: A super-resolution digital tomosynthesis system for imaging an object including a source configured to emit penetrating particles toward an object; a detector configured to acquire a series of projection images of the object in response to the penetrating particles from the source; positioning apparatus configured to position the source and the detector; and an imaging system coupled to the source, the detector, and the positioning apparatus. The imaging system is configured to control the positioning apparatus to position the source in relation to the detector along a scan path and to change a distance between the source and the detector, control the source and the detector to acquire the series of projection images along the scan path with the distance change between the source and detector, and construct a tomographic volume exhibiting super-resolution from data representing the acquired series of projection images.Type: GrantFiled: November 24, 2021Date of Patent: October 17, 2023Assignees: The Trustees of the University of Pennsylvania, Real Time Tomography, LLCInventors: Andrew D. A. Maidment, Raymond J. Acciavatti, Susan Ng, Peter A. Ringer, Johnny Kuo

Publication number: 20230240625Abstract: A contrast-enhanced digital tomosynthesis system with a source configured to emit penetrating particles toward an source, a positioning apparatus configured to position the source relative to the object and the detector, and an imaging system coupled to the source, the detector, and the positioning apparatus. The imaging system is configured to control the positioning apparatus to position the source and detector relative to the object, control the source and the detector to acquire the series of projection images, and construct a tomographic volume capable of exhibiting super-resolution morphology and contrast-enhancement arising from injection of an exogenous contrast agent from data representing the acquired series of projection images or a subset thereof.Type: ApplicationFiled: December 5, 2022Publication date: August 3, 2023Inventors: Andrew D.A. Maidment, Brian Lee, Susan NG, Peter A. Ringer, Johnny Kuo, Raymond J. Acciavatti

Patent number: 9743891Abstract: Tomosynthesis imaging methods, systems, and apparatus include a source to emit penetrating particles toward an object, a detector to acquire a series of projection images responsive to the penetrating particles, and a positioning system to position the source with respect to the object and the detector. An imaging system controls the positioning apparatus, source, and detector to acquire images along a primary scan direction with offsets in a secondary scan direction. An oscillatory velocity may be applied to the source to reduce focal spot blur. Tomographic volumes are constructed that are capable of exhibiting super-resolution from data representing the acquired series of projection images taking the primary scan direction and the offsets into consideration.Type: GrantFiled: July 9, 2013Date of Patent: August 29, 2017Assignees: The Trustees of the University of Pennsylvania, Real Time Tomography, LLCInventors: Andrew D. A. Maidment, Raymond J. Acciavatti, Predrag Bakic, Susan Ng, Peter A. Ringer, Johnny Kuo
