Claim of US Patent No. 10,462,382

1. An imaging apparatus configured for imaging an intervention device and body tissue surrounding said device using a single imaging modality, said apparatus comprising:image acquisition and formation circuitry configured to generate a plurality of first images and a plurality of second images of a target area of a subject from a single imaging modality,
wherein the plurality of first images and the plurality of second images are each generated by imaging from different acoustic windows,
wherein individual images of the plurality of first images and individual images of the plurality of second images are generated in an alternating manner,
wherein the plurality of first images are obtained using one or more first parameter values specific for imaging an interventional device in the target area,
wherein the plurality of second images are obtained using one or more second parameter values specific for imaging tissue within the target area such that the image acquisition circuitry toggles back and forth between using the one or more first parameter values and the one or more second parameter values; and
image combination circuitry configured for forming a plurality of combined images of the interventional device surrounded by the tissue using the individual images of the plurality of first images and the individual ones of the plurality of second images, wherein forming comprises:
segmenting at least a portion of the individual ones of the plurality of first images, the segmented portion includes the interventional device and its surrounding boundary area; and
overlapping the segmented portion onto the individual ones of the plurality of second images to form the plurality of combined images, the plurality of combined images comprising the tissue, the interventional device, and the boundary area.
