Abstract
A method for fabricating an intravascular imaging assembly is provided. In one embodiment, the method includes forming a stacked structure (415) having a plurality of sacrificial material layers disposed between a plurality of ultrasound material layers in an alternating pattern; dicing the stacked structure (420) to form a plurality of elongated strips, each comprising an array of ultrasound elements defined by the plurality of ultrasound material layers and spacers defined by the plurality of sacrificial material layers; coupling a first elongated strip (430) of the plurality of elongated strips to a flexible circuit substrate; and removing the spacers (435) of the first elongated strip from the flexible circuit substrate.
