    Abstract: A controller (310) for identifying positioning of an intravascular ultrasound probe (952) includes a memory (362) that stores instructions (884) and a processor (361) that executes the instructions (884). When executed by the processor (361), the instructions (884) cause the controller (310) to execute a process that includes receiving first signals from at least one element of the intravascular ultrasound probe (952). The process also includes receiving second signals from an external ultrasound probe. Based on the first signals and the second signals, the controller (310) determines a position of the intravascular ultrasound probe (952) in a tracking space that includes the intravascular ultrasound probe (952) and the external ultrasound probe.

    Abstract: An acoustic probe connectable to an imaging system. The acoustic probe has a substrate with first and second principal surfaces, at least one device insertion port comprising an opening passing through the substrate from the first principal surface to the second principal surface, and an array of acoustic transducer elements supported by the substrate and disposed around the at least one device insertion port. The acoustic probe comprising an instrument guide disposed within the device insertion port, the instrument guide being configured to selectively allow the interventional device to move freely within the device insertion port and to selectively lock the interventional device within the device insertion port in response to a user input via a user interface connected to the acoustic probe.

    Abstract: A controller (220) for determining a shape of an interventional medical device in an interventional medical procedure based on a location of the interventional medical device includes a memory (221) that stores instructions and a processor (222) that executes the instructions. The instructions cause a system (200) that includes the controller (220) to implement a process that includes obtaining (S320) the location of the interventional medical device (201) and obtaining (S330) imagery of a volume that includes the interventional medical device. The process also includes applying (S340), based on the location of the interventional medical device (201), image processing to the imagery to identify the interventional medical device (201) including the shape of the interventional medical device (201). The process further includes (S350) segmenting the interventional medical device (201) to obtain a segmented representation of the interventional medical device (201). The segmented representation of the interventional medical device (201) is overlaid (S360) on the imagery.

    Abstract: An ultrasonic diagnostic imaging system performs elastography using mechanically generated vibrations from a vibration assembly attached to an ultrasound probe. An attachment member attaches the vibration assembly to the probe. A vibration motor is mounted in a motor mount and applies vibration energy to the body in which shear waves are to be measured, at a location adjacent to the probe. The vibration motor mount is coupled to the attachment member by a vibration isolation element such as a spring, rubber band, or elastic compound which isolates the probe from deleterious vibration energy from the vibration motor.
