1. An intraluminal ultrasound imaging catheter, comprising:
a flexible elongate member configured to be positioned within a body lumen of a patient;
a support member coupled to a distal portion of the flexible elongate member, wherein the support member comprises:
a hollow inner member comprising a first material; and
a first annular member positioned around a perimeter of the hollow inner member at a proximal portion of the hollow inner member, wherein the first annular member extends radially outward from the hollow inner member, and wherein the first annular member comprises a second material that is different from the first material; and
an ultrasound scanner assembly configured to obtain ultrasound imaging data of the body lumen, wherein the ultrasound scanner assembly comprises a flexible substrate positioned around the first annular member such that the flexible substrate is distinct from the first annular member.
