Patent number: 11719778Abstract: Methods and systems generate synthetic late gadolinium enhancement (LGE) magnetic resonance images using a magnetic resonance fingerprinting (MRF) acquisition. From a single acquisition, MRF image data is obtained, including co-registered T1 and T2 tissue property maps. Different tissue regions of interest are identified, such as viable myocardium, scar, and blood and T1 and T2 values for each are determined. Based on these, different sets of pulse sequence parameters are determined, e.g., using different synthetic image contrast models receiving the MRF image data. Synthetic LGE images at different contrasts are generated as a result, including a synthetic bright-blood LGE image, a synthetic dark-blood/gray-blood LGE image, and a synthetic optimized imaged.Type: GrantFiled: January 31, 2022Date of Patent: August 8, 2023Assignees: REGENTS OF THE UNIVERSITY OF MICHIGAN, CASE WESTERN RESERVE UNIVERSITY, UNIVERSITY HOSPITALS CLEVELAND MEDICAL CENTERInventors: Jesse Hamilton, Imran Rashid, Nicole Seiberlich, Sanjay Rajagopalan

Patent number: 11714330Abstract: Integrated Optical Phased Array device is a good potential solution for the solid-state LIDAR technology in the application of autonomous driving technique. However, some difficulties still limit the development of OPA devices, one of them is the conflict between the requirement of fewer units in the phase-tuning system and more elements in the emitting system. The present disclosure provides an approach of a Phase-Combining Waveguide Doubler (PCWD) to address this issue. This device can double the waveguide number without any phase mismatch. It enables the capability to control 2N?1 emitting elements with N phase shifters. The device is competitive to any grating coupler array based or end-fire based emitting method, which can potentially satisfy the requirement of a sub-wavelength pitch.Type: GrantFiled: April 27, 2022Date of Patent: August 1, 2023Assignee: THE REGENTS OF THE UNIVERSITY OF MICHIGANInventors: Ya Sha Yi, Da Chuan Wu
