Abstract: An instrument for internal mapping includes a flexible elongated portion (702) and an expandable portion (710) coupled distally to the elongated portion, the expandable portion having one or more expandable loops. An array of sensors (706) and electrodes (708) is distributed on the expandable portion and is configured to concurrently register the instrument to real-time images of an anatomy using the sensors and measure electrical characteristics of the anatomy with the electrodes to generate an electro-physiology (EP) map having the anatomy and intensities of the electrical characteristics mapped together in the real-time images.

Abstract: A system for tracking an instrument includes two or more sensors (22) disposed along a length of an instrument and being spaced apart from adjacent sensors. An interpretation module (45) is configured to select and update an image slice from a three-dimensional image volume in accordance with positions of the two or more sensors. The three-dimensional image volume includes the positions two or more sensors with respect to a target in the volume. An image processing module (48) is configured to generate an overlay (80) indicating reference positions in the image slice. The reference positions include the positions of the two or more sensors and relative offsets from the image slice in a display to provide feedback for positioning and orienting the instrument.

Abstract: A controller for maintaining alignment of X-Ray imagery and ultrasound imagery includes a memory that stores instructions, and a processor that executes the instructions. When executed by the processor, the instructions cause the controller to execute a process that includes receiving data from an X-Ray system used to perform X-Ray imaging, and receiving data from an ultrasound imaging probe used to perform ultrasound imaging. The process executed by the controller also includes registering imagery based on X-Rays to imagery from the ultrasound imaging probe based on an X-Ray image of the ultrasound imaging probe among the imagery based on X-Rays, and detecting, from the data from the ultrasound imaging probe, movement of the ultrasound imaging probe.

Abstract: In one aspect, an ultrasound receive beamformer is configured for one-way only beamforming of transmissive ultrasound using one-way delays. The receive beamforming in some embodiments is used to track, in real time, a catheter, needle or other surgical tool within an image of a region of interest. The tool can have embedded at its tip a small ultrasound transmitter or receiver for transmitting or receiving the transmissive ultrasound. Optionally, additional transducers are fixed along the tool to provide the orientation of the tool.

Abstract: The following relates generally to systems and methods of transesophageal echocardiography (TEE) automation. Some aspects relate to a TEE probe with ultrasonic transducers on a distal end of the TEE probe. In some implementations, if a target is in a field of view (FOV) of the ultrasonic transducers, an electronic beam steering of the probe is adjusted; if the target is at an edge of the FOV, both the electronic beam steering and mechanical joints of the probe are adjusted; and if the target is not in the FOV, only the mechanical joints of the probe are adjusted.

Abstract: A controller (120) for simultaneously tracking multiple sensors in a medical intervention includes a circuit (121-181) that causes the controller (120) to execute a process. The process executed by the circuit (121-181) includes receiving first and second signals respectively from a first and a second passive ultrasound sensor (S2) used in the medical intervention. The first and second signals respectively include first and second sensor information indicative of respective locations of the first and the second passive ultrasound sensor (S2). The process executed by the circuit (121-181) also includes combining (120) the first signal and the second signal for transmission over only one channel, and providing the first signal and the second signal over the only one channel to a system (190) that determines the location of the first passive ultrasound sensor (S1) and the location of the second passive ultrasound sensor (S2) and that has only the one channel to receive the first signal and the second signal.

Abstract: A system for determining location of an interventional medical device within a patient includes a controller that controls an ultrasound probe to emit imaging beams at different times and angles relative to the ultrasound probe. The system also includes an interventional medical device with an attached sensor that receives the imaging beams together with repetitive noise. The controller further identifies the repetitive noise received at the sensor, including identifying the rate at which the repetitive noise is repeated and identifying the times at which the repetitive noise is received at the sensor. The controller further offsets the repetitive noise in signals received at the sensor by interpolating the signals based on the imaging beams. The controller determines the location of the interventional medical device based on the offset signals.

Abstract: A controller (240/340) for simultaneously tracking multiple interventional medical devices includes a memory (242/342) that stores instructions and a processor (241/341) that executes the instructions. When executed by the processor (241/341), the instructions cause the controller to execute a process that includes receiving timing information from a first signal emitted from an ultrasound probe (252/352) and reflective of timing when the ultrasound probe (252/352) transmits ultrasound beams to generate ultrasound imagery. The process executed by the controller also includes forwarding the timing information to be available for use by a first acquisition electronic component (232/332). The first acquisition electronic component (232/332) also receives sensor information from a first passive ultrasound sensor (S1) on a first interventional medical device (212/312). The timing information is used to synchronize the sensor information from the first passive ultrasound sensor (S1) on the first interventional medical device (212/312) with sensor information from a second passive ultrasound sensor (S2) on a second interventional medical device (216/316).
