A system and related methods for performing nerve detection during surgical access using ultrasound testing during surgery.

Systems and methods for delivery a medical device to a heart valve annulus are disclosed. A method of delivering a medical device to a heart valve annulus includes: (1) aligning a first imaging sensor such that a view of the first imaging sensor is along a primary plane of the heart valve annulus; (2) aligning a second imaging sensor such that a view of the second imaging sensor is along a longitudinal axis of the heart valve annulus; (3) attaching a delivery system holding the medical device to a delivery arm; (4) adjusting the delivery arm to set an angle of the delivery system perpendicular to the primary plane using images from the first imaging sensor; (5) adjusting the delivery arm to center the delivery device in the heart valve annulus using images from the second imaging sensor; and (6) deploying the medical device into the heart valve annulus.

A system may include an ultrasound probe and a controller unit configured to obtain a baseline ultrasound image of a patient's breast area using the ultrasound probe and to obtain a follow-up ultrasound image of the patient's breast area using the ultrasound probe. The controller unit may further be configured to use one or more machine learning models to compare the baseline ultrasound image with the follow-up ultrasound image; detect a change in a morphology or integrity of the patient's breast area based on the comparison of the baseline ultrasound image with the follow-up ultrasound image; and generate a recommendation for a medical intervention based on the detected change.

A method for postural independent location of targets in diagnostic images acquired by multimodal acquisitions, compensating for deformation of soft tissues due to changing posture, includes generating a transition of a digital image of the inside of a target region from a first to a second position by correlating the position of markers placed on the external surface of the target region in a digital image of the inside of the target region and in a digital representation of the external surface of the target region acquired by optically scanning the external surface; and at a later time registering the diagnostic image of the inside of the target region, transitioned into the second position, with a diagnostic image of the same target region acquired with the target region in the second position by matching a second representation of the external surface of the target region in the second position without markers with the diagnostic image of the inside of the target region transitioned into the second position.

For parametric ultrasound imaging with an ultrasound scanner, the values for multiple parameters are determined for tissue of a patient using ultrasound. The determination may be in response to a single activation, avoiding the user having to reconfigure and activate separately for each parameter. To assist in diagnosis, one or more indicators of quality of the measurements of the parameters are calculated and displayed to the user. To further assist in diagnosis, the measurement values for the patient are displayed relative to published or population values.

An ultrasound probe (104) includes a probe head (134). The probe head includes a transducer array (136) with a transducing surface (137), an instrument guide (142), and a light source (140). A method includes emitting a light beam, from a light source disposed on and adjacent to a transducer array of an ultrasound imaging probe, in a direction opposite of a transducing surface of the transducer array, at an inside wall of a cavity of a subject or object. A laparoscopic ultrasound imaging probe includes a shaft, a body, an articulating member that couples the probe head, and a handle coupled to the elongate shaft. The articulating probe head includes a transducer array that generates an ultrasound signal that traverses an image plane of the transducer array, an instrument guide, and a light source arranged to emit light in a direction opposite of the image plane.

A device for a mobile ultrasound unit having an ultrasound probe includes a trained orientation neural network and a result converter. The trained orientation neural network receives a non-canonical image of a body part from the mobile ultrasound unit and generates a transformation transforming between a position and rotation associated with a canonical image and a position and rotation associated with the non-canonical image. The result converter converts the transformation into position and/or rotation instructions of the probe and displays the position and/or rotation instructions to a user to change the position and/or rotation of the probe.

An implantable position detecting system is configured to detect a position of an implantable device with respect to a body structure. The system includes at least one proximity measuring transducer configured to be implanted on the body structure a distance from the implantable device, the at least one proximity measuring transducer being configured to receive energy from an external electromagnetic field generated by an external sensing interface, wherein the at least one proximity sensor is configured to emit an emitted signal responsive to the electromagnetic energy and to receive distance information comprising a sensing signal that is responsive to the distance from the implantable device.

Aspects of the technology described herein relate to techniques for guiding an operator to use an ultrasound device. Thereby, operators with little or no experience operating ultrasound devices may capture medically relevant ultrasound images and/or interpret the contents of the obtained ultrasound images. For example, some of the techniques disclosed herein may be used to identify a particular anatomical view of a subject to image with an ultrasound device, guide an operator of the ultrasound device to capture an ultrasound image of the subject that contains the particular anatomical view, and/or analyze the captured ultrasound image to identify medical information about the subject.

A system includes a processor circuit that receives the IVUS imaging data from the IVUS imaging catheter. The processor circuit identifies calcium based on the IVUS imaging data. The processor circuit determines, based on the identification of the calcium, at least one of: a distance between the calcium and the lumen border; or a density of the calcium relative to the tissue. The processor circuit outputs a screen display to a display in communication with the processor circuit. The screen display includes an IVUS image generated based on the IVUS imaging data; and at least one of: a visual representation of the distance; or a visual representation of the density.
