Abstract: A wearable ultrasound patch may include one or more layers, including a backing layer, a transducer layer, a matching layer, and an adhesive layer. The matching layer may include liquid-metal microdroplets dispersed within an elastomer. A volume loading and/or diameter of the liquid-metal microdroplets may tune the acoustic impedance of the matching layer such that the matching layer may provide acoustic matching via a geometric mean between an acoustic impedance of piezoelectric elements of the transducer layer and a skin on which the wearable ultrasound patch is worn. The wearable ultrasound patch may be used in a system with a pulser-receiver.

Abstract: Systems and methods are disclosed for reducing a comet tail aberration in an image of an ablation catheter. In one example, the method includes receiving ICE images depicting the ablation catheter tip and an area proximate to the ablation catheter tip; automatically determining, by the computer system, a location of the tip of the ablation catheter in the received ICE images; automatically determining, by the computer system, the presence of a comet tail aberration in a region of interest (ROI) near the ablation catheter tip in the received ICE images; and in response to determining the aberration is present in the ROI, automatically changing, by the computer system, an imaging characteristic of the ICE imaging system to affect the appearance of the aberration in the ROI in subsequent images generated by the ICE imaging system using the changed imaging characteristic.
