Classification: CPC A | IPC A

Claim 14:
15. A method of imaging within a patient body, comprising:
receiving, at a computing device in communication with a radiographic imaging unit, a radiographic image representative of an ultrasound imaging device positioned within the patient body,
wherein the ultrasound imaging device comprises an imaging assembly disposed at a distal portion of a flexible elongate member,
wherein the imaging assembly comprises:
an array of imaging elements;
a circuit board comprising a first surface and an opposite, second surface; and
a plurality of electronic components mounted only on the first surface and electrically coupled to the circuit board to perform an electrical function associated with the array of imaging elements,

wherein each of the plurality of electronic components is radiopaque such that the plurality of electronic components itself comprises a radiopaque arrangement,
wherein the radiopaque arrangement comprises a top, a bottom, a first side, and a second side,
wherein the radiopaque arrangement comprises an asymmetric shape such that:
the first side of the radiopaque arrangement comprises a first non-planar outline of the plurality of electronic components and a planar outline of the second surface; and
the second side of the radiopaque arrangement comprises a different, second non-planar outline of the plurality of electronic components and the planar outline of the second surface; and

determining, by the computing device, an orientation of the ultrasound imaging device using at least one of the first non-planar outline or the second non-planar outline in the radiographic image.
