Apparatus for adaptively scheduling ultrasound device actions includes a probe interface, a beamer, a receiver, a processor, and a memory. The probe interface may interface with probe units to transmit signals generated by the beamer to the probe units and to receive data signals from the probe units. The processor may be coupled to the probe interface, the beamer, and the receiver. The memory may store instructions, which when executed by the processor, causes the processor to generate a task list that includes a timed beam firing sequence and to signal to the beamer to generate signals to the probe units associated with the plurality of task actions. The task list may include a plurality of task actions associated with probe units, and the processor may signal to the beamer in accordance with the timed beam firing sequence. Other embodiments are also described.

The present technology relates generally to receiving arrays to measure a characteristic of an acoustic beam and associated systems and methods. The receiving arrays can include elongated elements having at least one dimension, such as a length, that is larger than a width of an emitted acoustic beam and another dimension, such as a width, that is smaller than half of a characteristic wavelength of an ultrasound wave. The elongated elements can be configured to capture waveform measurements of the beam based on a characteristic of the emitted acoustic beam as the acoustic beam crosses a plane of the array, such as a transverse plane. The methods include measuring at least one characteristic of an ultrasound source using an array-based acoustic holography system and defining a measured hologram at the array surface based, at least in part, on the waveform measurements. The measured hologram can be processed to reconstruct a characteristic of the ultrasound source. The ultrasound source can be calibrated and/or re-calibrated based on the characteristic.

Various example embodiments of the present disclosure provide systems and methods for the dynamic correction and reduction of thermal variations in skull-induced aberrations during a focused ultrasound therapy procedure. Unlike conventional approaches involving static corrections for skull-induced aberrations, various example embodiments of the present disclosure employ ultrasound detection and a skull thickness estimate from volumetric image data to intermittently and dynamically determine corrections for skull-induced aberrations, such that aberration correction reduction is updated intraoperatively and maintained despite local thermally-induced changes in the speed of sound of the local skull region due to intraoperative intracranial heating. Furthermore, in some example embodiments, a measure dependent on the speed of sound with the skull is intraoperatively determined and compared to a previously determined value of the measure to determine a change in the skull temperature, based on a pre-determined relationship between changes in the measure and changes in skull temperature.

A processor in an ultrasound imaging system identifies faults or errors in the system. In one embodiment, fault or error conditions are detected by monitoring system parameters during a self-test. In another embodiment, a processor provides ultrasound image data to a trained neural network to identify fault conditions in a transducer or the imaging system. In some embodiments, the processor makes adjustments to one or more operating parameters to compensate for the identified fault conditions so that the system continues to operate and produce images with the detected fault condition.

The present invention relates to an apparatus for tracking a position of an interventional device respective an image plane of an ultrasound field. The position includes an out-of-plane distance (Dop). A geometry-providing unit (GPU) includes a plurality of transducer-to-distal-end lengths (Ltde.sub.1 . . . n), each length corresponding to a predetermined distance (Ltde) between a distal end of an interventional device and an ultrasound detector attached to the interventional device, for each of a plurality of interventional device types (T.sub.1 . . . n). An image fusion unit (IFU) receives data indicative of the type (T) of the interventional device being tracked; and based on the type (T): selects from the geometry-providing unit (GPU), a corresponding transducer-to-distal-end length (Ltde); and indicates in a reconstructed ultrasound image (RUI) both the out-of-plane distance (Dop) and the transducer-to-distal-end length (Ltde) for the interventional device within the ultrasound field.

Systems and methods for triggering the acquisition of elastography measurements based on motion data are disclosed. Motion data may be acquired by Doppler mode imaging in some embodiments. The motion data may be used to generate a trigger signal. The trigger signal may be provided to a transmit controller. The transmit controller may cause an ultrasound transducer to acquire elastography measurements responsive to the trigger signal.

A method for determining a geometry of an ear canal or a portion of an ear of a person may include filling the ear canal and/or the portion of the ear with a liquid or a gel, inserting a capacitive micromachined ultrasonic transducer probe or a piezoelectric micromachined ultrasonic transducer probe, acquiring data using the probe, and processing the acquired data to obtain a 2D or 3D image of the ear canal and/or the portion of the ear.

Systems, devices, and methods are disclosed for acquiring and providing information about orthopedic features of a body using acoustic energy. In some aspects, an acoustic orthopedic tracking system includes portable acoustic transducers to obtain orthopedic position information for feeding the information to an orthopedic surgical system for surgical operations.
