ABSTRACT:
The present invention generally relates to medical devices, and more particularly to an improved intravascular device. In one embodiment, an intravascular device includes a catheter having proximal and distal portions, and a phased array of imaging elements, having edge elements each having angles of emission, located in the distal portion of the catheter, wherein the phased array is concaved having a radius of curvature such that when the phased array is steered in a maximal azimuthal direction, the angles of emission of the edge elements are substantially similar.
