Patent number: 11872025Abstract: An apparatus for use in a magnetic resonance (MR) system for capturing an MR Elastography measurement of a biological lifeform may include a platform; a gel pad on a surface of the platform; and a sensor array. In some embodiments, the sensor array includes at least one ultrasound transducer, and at least one radiofrequency (RF) transmitter and receiver coil. The sensor array is at least partially embedded within the gel pad, and the gel pad is configured to provide mechanical impedance matching between the at least one ultrasound transducer and the biological lifeform. In some embodiments, a system includes the apparatus and an MR system, the MR system including an ultrasonic wave generator, an interface circuit, and a computing device. In some such embodiments, the ultrasonic wave generator is configured to generate one or more shear waves in the biological lifeform.Type: GrantFiled: March 17, 2017Date of Patent: January 16, 2024Assignee: Q Bio, Inc.Inventors: Jeffrey H.

Publication number: 20240005514Abstract: During operation, a system may obtain first and second magnetic resonance (MR) measurements associated with a biological lifeform, where the first and second MR measurements were acquired while the biological lifeform engaged in free breathing and/or without prospective gating based on a cardiac rhythm of the biological lifeform, and the first and second MR measurements were acquired at different times. Then, the system may dynamically determine first and second instances of one or more anatomical structures associated with the biological lifeform based at least in part on the first and second MR measurements, and a segmentation technique. Next, the system may perform a quantitative comparison of the first instance of the one or more anatomical structures and the second instance of the one or more anatomical structures, where the quantitative comparison has an uncertainty of less than a predefined value.Type: ApplicationFiled: June 29, 2023Publication date: January 4, 2024Inventors: Jeffrey H. Kaditz, Aikaterini Kotrosou, Gordon Duffley, Blake Edwin Zimmerman, Thomas Witzel, Adam Patrick Harrison

Publication number: 20230204700Abstract: A computer system that performs a sparsity technique is described. During operation, the computer system accesses or obtains information associated with non-invasive measurements performed on at least an individual, historical non-invasive measurements, and a dictionary of predetermined features or basis functions associated with the historical non-invasive measurements. Note that the non-invasive measurements and the historical non-invasive measurements may include or correspond to magnetic resonance (MR) measurements. For example, the MR measurements may include magnetic resonance imaging (MRI) scans. Then, the computer system updates the dictionary of predetermined features based at least in part on the non-invasive measurements and the historical non-invasive measurements, where the updating includes performing a minimization technique with a cost function having an L2-norm term and an L0-norm term.Type: ApplicationFiled: February 22, 2023Publication date: June 29, 2023Inventors: Guanhua Wang, Matteo Alessandro Francavilla, Thomas Witzel, Jeffrey H.

Publication number: 20210311150Abstract: During operation, a system may apply an external magnetic field and an RF pulse sequence to a sample. Then, the system may measure at least a component of a magnetization associated with the sample, such as MR signals of one or more types of nuclei in the sample. Moreover, the system may calculate at least a predicted component of the magnetization for voxels associated with the sample based on the measured component of the magnetization, a forward model, the external magnetic field and the RF pulse sequence. Next, the system may solve an inverse problem by, iteratively modifying the parameters associated with the voxels in the forward model until a difference between the predicted component of the magnetization and the measured component of the magnetization is less than a predefined value. Note that the calculations may be performed concurrently with the measurements and may not involve performing a Fourier transform.Type: ApplicationFiled: June 21, 2021Publication date: October 7, 2021Inventors: Jeffrey H.
