Phased array calibration for geometry and aberration correction
10 Aug 20
Various approaches for calibrating the geometry of an ultrasound transducer having multiple transducer elements include providing an acoustic reflector spanning an area traversing by multiple beam paths of ultrasound waves transmitted from all (or at least some) transducer elements to a focal zone; causing the transducer elements to transmit the ultrasound waves to the focal zone; measuring reflections of the ultrasound waves off the acoustic reflector; and based at least in part on the measured reflections, determining optimal geometric parameters associated with the transducer elements.

Systems and methods for correcting measurement artifacts in MR thermometry
8 Jun 20
Systems and methods for performing magnetic resonance (MR) thermometry include a magnetic resonance imaging (MRI) unit and a controller in communication with the MRI unit and configured to cause the MRI unit to acquire one or more baseline phase images of an imaging region and one or more treatment phase images of the imaging region subsequent to a temperature change of a subregion within the imaging region, electronically generate a thermal map pixelwise indicating the temperature change of the subregion based at least in part on the acquired baseline phase image and treatment phase image, computationally predict the temperature change of the subregion based at least in part on energy deposited in the subregion during treatment without reference to the generated thermal map, and determine whether the thermal map is inaccurate based at least in part on the temperature change of the subregion indicated by the thermal map and the predicted temperature change of the subregion.

Utility
Therapeutic ultrasound with reduced interference from microbubbles
16 Mar 20
Various approaches for reducing microbubble interference with ultrasound waves transmitted from multiple transducer elements and traversing tissue onto a target region include measuring microbubbles in high-throughput areas of ultrasound exposure and reducing the amount of microbubbles using the ultrasound waves.

Utility
Cavitation localization
2 Mar 20
Various approaches for detecting microbubble cavitation resulting from ultrasound waves transmitted from an ultrasound transducer include associating at least one time-domain reference signal with microbubble cavitation; causing the transducer to transmit one or more ultrasound pulse; acquiring, in the time domain, an echo signal from microbubbles in response to the transmitted ultrasound pulse(s); correlating at least a portion of the echo signal to at least a corresponding portion of the time-domain reference signal based on similarity therebetween; and detecting the microbubble cavitation based on the corresponding portion of the reference signal.

Systems and methods for avoiding MRI-originated interference with concurrently used systems
24 Feb 20
MRI interference with a concurrently operated system may be reduced or corrected by subtracting the MRI interference from signals measured using the concurrently operated system.

Utility
Motion tracking during non-invasive therapy
11 Nov 19
During a focused-ultrasound or other non-invasive treatment procedure, the motion of the treatment target or other object(s) of interest can be tracked in real time based on (i) the comparison of treatment images against a reference library of images that have been acquired prior to treatment for the anticipated range of motion and have been processed to identify the location of the target or other object(s) therein and (ii) complementary information associated with the stage of the target motion during treatment.

Utility
Systems and methods for optimizing transskull acoustic treatment
28 Oct 19
Skull inhomogeneity may be quantified in accordance with the skull density measured in skull images acquired using a conventional imager; the quantified inhomogeneity may then be used to determine whether the patient is suitable for ultrasound treatment and/or determine parameters associated with the ultrasound transducer for optimizing transskull ultrasound treatment.

Utility
Rib identification for transcostal focused ultrasound surgery
21 Oct 19
A method for transcostal ultrasound treatment of tissues includes determining rib locations, e.g., based on ultrasound reflections off the ribs or acoustic radiation force signals, and transcostally focusing ultrasound into the tissue while minimizing damage to the ribs.
