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 acoustic imaging apparatus and method receive a sensor signal from a passive sensor disposed on a surface of an intervention device which is disposed in an area of interest, wherein the passive sensor is located at a fixed distance from the tip of the intervention device. A processor is configured to ascertain an estimated range of locations of the tip of the intervention device in an image plane by using the sensor signal and an estimated effective distance, projected onto the image plane, from the passive sensor to the tip of the intervention device.

Abstract: An acoustic imaging apparatus and method: produce acoustic images of an area of interest in response to one or more receive signals received from an acoustic probe in response to acoustic echoes received by the acoustic probe from the area of interest; 5 identify one or more candidate locations for a passive sensor disposed on a surface of an intervention device in the area of interest based on magnitudes of the acoustic echoes received by the acoustic probe from the candidate locations in the area of interest; use intra-procedural context-specific information to identify a one of the candidate locations which best matches the intra-procedural context-specific information as the estimated 10 location of the passive sensor; displaying the acoustic images on a display device; and display on the display device a marker in the acoustic images to indicate the estimated location of the passive sensor.

Abstract: A method is provided for determining whether a section of a lead has adhered to a blood vessel. The method comprises obtaining data corresponding to the blood vessel with a lead inside and determining motion vectors corresponding to the lead from the data corresponding to the blood vessel. The motion vectors are input into a machine learning algorithm trained to learn the correlation between the motion vectors and whether a section of a lead has adhered to a blood vessel and output an adherence level for segments of the lead.

Abstract: Methods, Apparatuses, and Systems of operating a laser atherectomy system to perform an endoscopic atherectomy procedure within a vessel at a therapeutic region of an anatomical condition by use of an atherectomy laser device coupled to an ultrasound imaging probe. The atherectomy laser device operates to generate photoacoustic signals from a light source of the atherectomy laser device to for guidance within the vessel and to characterize tissue about the therapeutic region by delivery of pulsed wavelengths within the vessel, and to perform operations of tissue ablation directed to the anatomical condition. This enables guidance of the atherectomy laser device by feedback from the viewing of photoacoustic images based on photoacoustic signals generated the atherectomy laser device and created in response to changes in acoustic intensity due to changes of optical wavelength monitored by the ultrasound imaging probe.

Abstract: A steerable multi-plane ultrasound imaging system (MPUIS) for steering a plurality of intersecting image planes (PL1 . . . n) of a beamforming ultrasound imaging probe (BUIP) based on ultrasound signals transmitted between the beamforming ultrasound imaging probe (BUIP) and an ultrasound transducer (S) disposed within a field of view (FOV) of the probe (BUIP). An ultrasound tracking system (UTS) causes the beamforming ultrasound imaging probe (BUIP) to adjust an orientation of the first image plane (PL1) such that a first image plane passes through a position (POS) of the ultrasound transducer (S) by maximizing a magnitude of ultrasound signals transmitted between the beamforming ultrasound imaging probe (BUIP) and the ultrasound transducer (S). An orientation of a second image plane (PL2) is adjusted such that an intersection (AZ) between the first image plane and the second image plane passes through the position of the ultrasound transducer (S).

Abstract: An ultrasound imaging system according to the present disclosure may include an ultrasound transducer assembly comprising a plurality of apertures that are configured to transmit signals toward and receive signals from a region of interest (ROI) of a subject, a tracking sensor disposed within the subject and configured to move within the ROI, the sensor being responsive to signals transmitted by the apertures, and at least one processor in communication with the ultrasound transducer assembly and the tracking sensor. The at least one processor may be configured to generate a first image of a first portion of the ROI from signals received from at least one activated aperture, identify a position of the tracking sensor using signal data from the tracking sensor that corresponds to at least one signal transmitted by the apertures, and generate a second image of a second portion of the ROI from signals received from at least one other aperture activated based on the identified position, wherein the second portion of the ROI is different from the first portion of the ROI.
