    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).

    Abstract: An ultrasound imaging system (1) comprises an ultrasound transducer array (100) comprising a plurality of ultrasound transducer tiles (101a-d), each of said tiles having an independently adjustable orientation such as to conform an ultrasound transmitting surface to a region of a body (50) including a foreign object such as a pacemaker, a stent, or an interventional tool (200). Using a known spatial arrangement of a plurality of features (201-204) of the foreign object (200), the respective ultrasound images generated by the ultrasound transducer tiles are registered in order to generate a composite image, in which the position and orientation of the foreign object in the individual images is superimposed. The position and orientation of an interventional tool may be determined for each image using object recognition algorithms or using acoustic feedback information provided by at least three ultrasound sensors (201-204) arranged in a known spatial arrangement on the interventional tool.

    Abstract: A vibration actuator (10) for mechanically generating a shear wave comprises a plurality of n rotational vibrators (141, 142, 143), an accelerometer (16), and a controller (18). The plurality of n rotational vibrators enables generation of a vibration vector with desired directional behavior selected from a plurality of vibration vectors (34, 36, 38) of different directional behaviors. Each rotational vibrator comprises an independently controllable motor (20) having a drive shaft (22) and an eccentric disk (24). The accelerometer is arranged to detect a vibration vector generated by at least two of the plurality of n rotational vibrators. The controller selectively controls a first set of two rotational vibrators to rotate respective eccentric disks in a first coordinated manner to produce a first vibration vector, and a second set of two rotational vibrators to rotate respective eccentric disks in a second coordinated manner to produce a second vibration vector, with different respective directional behaviors.

    Abstract: A controller for reducing noise in an ultrasound environment includes 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 controlling emission, by an ultrasound probe, of multiple beams each at a different combination of time of emission and angle of emission relative to the ultrasound probe. The process also includes identifying repetitive noise from a first source received with the imaging beams at a sensor on an interventional medical device, including a rate at which the repetitive noise from the first source repeats and times at which the repetitive noise from the first source is received. The process also includes interpolating signals based on the imaging beams received at the sensor to offset the repetitive noise from the first source at the times at which the repetitive noise from the first source is received.

    Abstract: In an embodiment, a computer-implemented method (100) is described. The method (100) comprises receiving (102) input data. The method 100 further comprises generating (104) location data indicative of a location of any detected at least one feature of interest in the received input data. The location data is generated using a first machine learning, ML, model configured to detect whether or not there is at least one feature of interest in the received input data. The first ML model is trained based on a learning process implemented by a second ML model configured to detect whether or not there is at least one feature of interest in the received input data. The first ML model and the second ML model are each configured to use an attention mechanism to generate: at least one attention map from at least one layer of the first ML model; and a plurality of attention maps from a plurality of layers of the second ML model. The first ML model comprises fewer layers than the second ML model. At least one attention map generated by the second ML model is used to train the first ML model. The first and second ML models comprise a transformer-based object detection architecture.

    Abstract: A system includes an acoustic probe and an acoustic imaging machine. The acoustic probe includes a substrate with first and second principal surfaces, a device insertion port with 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 device insertion port. The acoustic imaging machine may systematically vary the size and/or position of the active acoustic aperture of the probe by providing transmit signals to selected acoustic transducer elements to cause the array to transmit an acoustic probe signal to an area of interest and may record a feedback signal of the transmit signals from an acoustic receiver provided at a distal end of an interventional device passed through the device insertion port into the area of interest to find an active acoustic aperture having optimal acoustic performance.
