Solid-state ultrasound imaging devices, systems, and methods are provided. Some embodiments of the present disclosure are particularly directed to transducer arrays that employ a relatively large number of transducers yet are configured for fitting within space constraints associated with lumen and/or catheter dimensions. In one embodiment, an ultrasound imaging device includes a flexible elongate member； and an ultrasound scanner assembly disposed at a distal portion of the flexible elongate member, wherein the ultrasound scanner assembly includes an ultrasound transducer array, wherein the ultrasound transducer array includes a plurality of rings of transducers. In one aspect, the transducer arrays may be oscillated between multiple positions along the length of the flexible elongate member.
