Patent number: 12360193Abstract: The present disclosure provides magnetic resonance phantom imaging phantoms and method of assembling thereof. In one aspect, a magnetic resonance imaging phantom can include a plurality of modular components. The plurality of modular components can include a first modular component, a second modular component, a shell, and a lid. The second modular component can be different than the first modular component. The shell can be structured to receive at least one modular component. The lid can be attachable to the shell to enclose the at least one modular component received within the shell.Type: GrantFiled: December 28, 2022Date of Patent: July 15, 2025Assignee: neuro42, Inc.Inventors: Hung-Yu Lin, Donghui Yin, Nguyen Pham, Sree Poojitha Yerramsetti, Randy Link, Nio Anderson, Rishabh Ostawal, Joyce Ye, Guanhao Fu, Ghoncheh Amouzandeh, Xiaowei Zou

System and method for removing electromagnetic interference from low-field magnetic resonance images
Patent number: 12270867Abstract: The present disclosure provides systems and methods for removing electromagnetic interference from low-field magnetic resonance images. In one aspect, a method can include projecting a low-field strength magnetic field toward an object of interest located within a field of view and transmitting a radio frequency pulse sequence to a radio frequency coil assembly configured to selectively excite magnetization in the object of interest within the field of view. The method can further include receiving an output signal from the radio frequency coil assembly during a signal acquisition period and receiving a sample signal from the radio frequency coil assembly during an interference period. The method can further include comparing the output signal and the sample signal to identify an interference component and adjusting the output signal based on the interference component.Type: GrantFiled: November 19, 2022Date of Patent: April 8, 2025Assignee: NEURO42 INC.Inventors: Benjamin Inglis, Donghui Yin, Haidong Peng, Ghoncheh Amouzandeh, Xiaowei Zou -
Patent number: 12113095Abstract: This application discloses a planar inductor. The planar inductor includes a first inductor module and a second inductor module that are connected in parallel. A direction of a magnetic line of the first inductor module is opposite to a direction of a magnetic line of the second inductor module, so that the magnetic lines can form a self-close loop in the planar inductor, and impact of a far magnetic field generated by the inductor on the outside, especially a nearby inductor, can be greatly reduced, thereby reducing crosstalk between the inductors, that is, reducing a phase noise, and increasing a Q value of the inductor. In addition, this application further provides a semiconductor chip that includes the planar inductor.Type: GrantFiled: March 18, 2021Date of Patent: October 8, 2024Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Xiaowei Zou, Chengbo Qiu, Haisheng Lu

Publication number: 20240230804Abstract: Various systems and methods for T2-weighted and/or diffusion weighted chirped-CPMG sequences are disclosed herein. In one aspect, a method can include projecting a magnetic field along a longitudinal axis and toward an object of interest and transmitting a radio frequency pulse sequence to a radio frequency coil assembly configured to selectively excite magnetization in the object of interest. The radio frequency pulse sequence can include a frequency-swept excitation pulse and a series of frequency-swept refocusing pulses following the excitation pulse. In some aspects, the radio frequency pulse sequence can include a frequency-swept recovery pulse following the series of refocusing pulses. In some aspects, the method can include transmitting a preparation radio frequency pulse sequence to the radio frequency coil assembly.Type: ApplicationFiled: January 11, 2023Publication date: July 11, 2024Applicant: Neuro42 Inc.Inventor: Xiaowei ZOU
