Abstract: A facility for automatically establishing measurement location controls for Doppler ultrasound studies is described. The facility receives a first ultrasound image, and user input selecting an anatomical structure appearing in it. The facility performs localization to determine the location of the selected anatomical structure in the initial image, and determines a first placement of measurement location controls relative to the structure. On the ultrasound machine, the facility invokes one or more first Doppler ultrasound modes using the first placement. The facility receives a second ultrasound image produced by the ultrasound machine using the one or more first modes; determines a flow location and direction based on the second ultrasound image; and determines a second placement relative to the flow location. The facility invokes one or more second Doppler ultrasound modes using the second placement, and receives results from the invocation of the one or more second Doppler ultrasound modes.

Abstract: An ultrasound system comprising a portable ultrasound probe and a docking station provides enhanced ultrasound functionality. One or more first transducer elements transmit an ultrasound signal toward a target structure in a region of interest. Processing circuitry controls transmission of the ultrasound signal, while driving circuitry that is operatively coupled to the one or more first transducer elements and the processing circuitry drives the transmission of the ultrasound signal. The ultrasound probe further includes one or more second transducer elements that receive echo signals returning from the target structure in response to transmission of the ultrasound signal, and a power supply that provides power to the driving circuitry for transmission of the ultrasound signal. The docking station includes an interface that is couplable to the ultrasound probe and circuitry that electrically couples to the ultrasound probe via the interface and enhances the ultrasound functionality of the ultrasound probe.

Abstract: Intraoperative ultrasound (US) is integrated with stereotactic systems, where a system interactively registers two-dimensional (2D) US and three-dimensional (3D) magnetic resonance (MR) images. The registration is based on tracking a US probe with a bC magnetic position sensor. A transformation algorithm is performed to transform coordinates of points between two different spaces, where MR and US image spaces are independently registered with the position sensor space and where coordinate points can be registered between the MR and US spaces. A calibration procedure can be performed, and a phantom can be used to determine and analyze registration errors. The registered MR images can reconstructed using either zero-order or first-order interpolation.
