1. A method for providing intra-operative feedback during an ablation procedure, the method comprising:
providing an imaging system comprising an ultrasound imaging device and a console operably associated with the imaging device;
capturing, via the imaging device, image data associated with intravascular tissue prior to undergoing an ablation procedure, during the ablation procedure, and after the ablation procedure, the image data comprising ultrasound signal data captured from different angular acquisitions using emitted plane-waves and captured over a defined frequency range comprising multiple transmit frequency acquisitions with receive frequency filters, wherein the ultrasound signal data comprises at least one of plane wave data and diverging wave data;
processing, via the console, the ultrasound signal data and extracting functional and anatomical parameter data of the intravascular tissue using a functional imaging algorithm and an anatomical imaging algorithm;
reconstructing, via the console, at least one of two-dimensional (2D), three-dimensional (3D), and four-dimensional (4D) images from the image data based on the extracted functional and anatomical parameter data; and
displaying, via an interactive interface, the images to an operator prior to, during, and after carrying out the ablation procedure, at least some of the images showing one or more lesion formations in a targeted portion of the intravascular tissue as a result of the ablation procedure, thereby providing the operator with visual indication of the state of the intravascular tissue undergoing ablation.
