摘要： A balloon valvuloplasty catheter may include an elongate shaft having a guidewire lumen and a device lumen extending longitudinally therein, an expandable balloon secured to a distal portion of the elongate shaft, and an intravascular ultrasound catheter slidably disposed within the device lumen. The device lumen is in fluid communication with an interior of the expandable balloon. A method of preparing a native aortic heart valve of a patient's heart for transcatheter aortic valve replacement may include using the balloon valvuloplasty to observe via intravascular ultrasound and evaluate a position of the native leaflets relative to the left and right coronary artery ostia to determine if the native leaflets block the left coronary artery ostium and/or the right coronary artery ostium when the expandable balloon is inflated.

摘要： A method for generating an ultrasound image includes receiving an image frame comprising consecutive ultrasound scan lines obtained using a rotating ultrasound imaging arrangement and determining at least a first cross-correlation value and a second cross-correlation value for each of a plurality of the scan lines. For each individual scan line of the plurality of scan lines, the first cross-correlation value comprises a cross-correlation coefficient between a first subframe comprising a plurality of consecutive scan lines including the individual scan line and a second subframe comprising a plurality of scan lines shifted from the first subframe by a first integer value. The second correlation value comprising a cross-correlation coefficient between the first subframe and a third subframe comprising a plurality scan lines shifted from the first subframe by a second integer value that is different from the first integer value. The method further includes evaluating, individually for multiple scan lines of the plurality of scan lines, whether the scan line being evaluated exhibits non-uniform rotation distortion using at least one of the first and second correlation values for the scan line being evaluated. A correction for non-uniform rotation distortion is applied using at least one of the first and second correlation values for at least one of the plurality of scan lines. An ultrasound image is generated using at least the plurality of scan lines with the applied correction and the ultrasound image is displayed.

摘要： A method for generating a composite image using an intravascular imaging device includes receiving reflected echo signals from at least one transducer along a first of a plurality of radial scan lines. The received echo signals are passed through a plurality of signal processing channels to form a plurality of filtered signals. The filtered signals include a high-resolution tissue structure signal and at least one first pre-blood-flow-mask signal. High-resolution tissue structure signals are processed to form a high-resolution tissue structural image. First pre-blood-flow-mask signals are cross-correlated with second pre-blood-flow-mask signals from an adjacent radial scan line to form blood-flow-mask signals. Blood-flow-mask signals are processed to form a blood-flow mask. For each pixel of the composite image, it is determined whether to use a corresponding pixel of the high-resolution tissue structural image or a corresponding pixel of the cross-correlated blood flow mask to generate the composite image pixel.
