Patent number: 11662416Abstract: A method, electromagnet device, and system for reducing a higher order term of a concomitant field in an imaging magnetic field during magnetic resonance imaging is described. The electromagnet system has a first shim coil configured to be driven to generate a first compensation magnetic field during imaging according to a first second-order compensation term, the first compensation magnetic field having a similar amplitude but opposite direction as that of a first second-order concomitant magnetic field.Type: GrantFiled: December 24, 2021Date of Patent: May 30, 2023Assignee: SYNAPTIVE MEDICAL INC.Inventors: Chad Harris, Geron Bindseil, Andrew T. Curtis

Patent number: 11474176Abstract: A method, device, and system for reducing inhomogeneity in an imaging magnetic field during magnetic resonance imaging is described. The method includes generating a corrective magnetic field during imaging, the corrective magnetic field having a first magnetic field component and a second magnetic field component with a phase separation therebetween. The first and second components are generated according to a stability parameter decomposed from a stability field that correct an instability identified within the imaging magnetic field.Type: GrantFiled: May 26, 2021Date of Patent: October 18, 2022Assignee: Synaptive Medical Inc.Inventors: Ian Connell, Chad Harris, Geron Bindseil, Andrew T.

Patent number: 11269025Abstract: The present disclosure provides a system for and a method of obtaining a magnetic resonance image by performing magnetic resonance imaging (MRI) at multiple slices simultaneously. The method comprises generating a multiband pulse sequence for spin-echo imaging, the pulse sequence comprising a multiband excitation pulse and at least one multiband refocusing pulse, wherein the multiband excitation pulse simultaneously excites multiple bands, wherein the at least one multiband refocusing pulse simultaneously refocuses the multiple bands, and wherein the phases of the bands excited by the multiband excitation pulse and the phases of the bands refocused by the at least one multiband refocusing pulse are set according to a single row of an orthogonal encoding matrix. The multiband excitation pulse and the at least one multiband refocusing pulse collectively form a multiband pulse pair.Type: GrantFiled: March 16, 2020Date of Patent: March 8, 2022Assignee: SYNAPTIVE MEDICAL INC.Inventors: Charles H. Cunningham, Jeffrey A. Stainsby, Andrew T. Curtis
