1. An intraluminal ultrasound imaging device, comprising:
a flexible substrate comprising:
a plurality of ultrasound transducer elements configured to obtain imaging data, wherein the plurality of ultrasound transducer elements is are disposed on a first segment of the flexible substrate;
a plurality of control circuits in communication with the plurality of ultrasound transducer elements, wherein the plurality of control circuits are disposed on a second segment of the flexible substrate;
a plurality of conductive traces extending between the plurality of ultrasound transducer elements and the plurality of control circuits;
a first grounding region disposed on the first segment located distal to the plurality of ultrasound transducer elements, wherein the first grounding region is configured to facilitate grounding of the plurality of ultrasound transducer elements; and
a second grounding region disposed on the second segment proximate to the plurality of control circuits such that the second grounding region is distinct from the first grounding region, wherein the second grounding region is configured to facilitate grounding of the plurality of control circuits;
a catheter configured to be positioned within a body lumen of a patient; and
a support member coupled to a distal portion of the catheter and defining guidewire lumen, wherein the flexible substrate is wrapped around the support member, the support member comprising:
a body; and
a plurality of flanges comprising a diameter larger than the body such that the flexible substrate is radially spaced from the body,
wherein the plurality of flanges comprises:
a first flange and a second flange configured to support the first segment of the flexible substrate such that the first flange and the second flange define a transducer portion of the body aligned with the plurality of ultrasound transducer elements; and
a third flange and a fourth flange configured to support the second segment of the flexible substrate such that the third flange and the fourth flange define a control portion of the body aligned with the plurality of control circuits.
