Abstract: An ultrasound system includes a processor and an ultrasound transducer array. The processor receives a first ultrasound image and a second ultrasound (1320) image from the transducer array. The first and second ultrasound images may be perpendicular to one another. The processor generates a score associated with the first ultrasound image and compares the score to a threshold score. Based on the score not satisfying the threshold score, the processor then determines a new imaging plane and directs the transducer array to obtain a third ultrasound image (1410) according to the new imaging plane. The third ultrasound image may also be perpendicular to the second ultrasound image. The processor circuit then displays the third ultrasound image and the second ultrasound image. The processor circuit also identifies an angle corresponding to the new imaging plane and displays an indicator (1342) overlaid over the second ultrasound image identifying the new imaging plane of the third ultrasound image.

Abstract: A system and method for providing guidance in an ultrasound imaging procedure involves presenting graphical user interface elements overlaid onto an external image of the subject's body. The system includes at least one camera for capturing the external image of the subject. The system may utilize trained artificial neural network(s) to identify locations in the external image that correspond to scanning zones of a scanning protocol. A probe placement marker is overlaid at each identified location to indicate the position of the probe's face onto the subject's body for acquiring a target view of the internal anatomy. Additional graphical elements may be presented via the guidance interface and results findings may optionally be overlaid onto the external image of the subject at the completion of the scan. In embodiments herein, imaging guidance is provided solely via the external images of the subject without displaying the ultrasound image data.

Abstract: The present disclosure provides techniques for free fluid estimation including identifying a region of free fluid in an diagnostic image, calculating a free fluid measure based on the region of free fluid identified in the diagnostic image, and generating a volume class for the region of free fluid in the diagnostic image, wherein the volume class is generated by comparison of the free fluid measure to a data set of previously stored free fluid measures. The present disclosure may be implemented as a method, in a device, a computer readable medium, and a system, among other form factors.

Abstract: The invention provides a method for guiding the acquisition of ultrasound data within a 3D field of view. The method begins by obtaining initial 2D B-mode ultrasound data of a cranial region of a subject from a reduced field of view at a first imaging location and determining whether a vessel of interest is located within the 3D field of view based on the initial 2D B-mode ultrasound data. If the vessel of interest is not located within the 3D field of view, a guidance instruction is generated based on the initial 2D B-mode ultrasound data, wherein the guidance instruction is adapted to indicate a second imaging location to obtain further ultrasound data. If the vessel of interest is located within the 3D field of view 3D Doppler ultrasound data is obtained of the cranial region from the 3D field of view.

Abstract: A method (20) and device for deriving an estimate of intracranial blood pressure based on motion data for a wall of an intracranial blood vessel, intracranial blood flow velocity, and a blood pressure signal measured at a location outside the brain. The method is based on identifying (28) a time offset between the two intracranial signals (vessel wall movement and vessel blood flow), and then applying (30) this offset to the blood pressure signal acquired from outside the brain to obtain a fourth signal, indicative of estimated intracranial blood pressure.

Abstract: Systems, devices, and methods for performing photoacoustic measurements using ultrasound-based guidance are provided. In one embodiment, an imaging system includes: an ultrasound imaging probe comprising an ultrasound transducer array, a processor circuit in communication with the ultrasound imaging probe, and a light source configured to emit light. The processor circuit receives first ultrasound data representative of an anatomical feature within a field of view, identifies a location of the anatomical feature within the field of view, and performs a photoacoustic measurement using the identified location of the anatomical feature. Performing the photoacoustic measurement includes: controlling the light source to emit light into the field of view and processing second ultrasound data representative of photoacoustic energy generated in the anatomical feature by the light source. The processor circuit then outputs a graphical representation of the photoacoustic measurement to a display.
