1. A downhole device comprising:
a housing deployable in a well;
an imaging sensor connected at a distal end of the housing and rotatable thereto, said sensor comprising an ultrasound phased-array arranged at least partly along a longitudinal axis of the housing, wherein the ultrasound phased-array is curvilinear in form with a plurality of transducer elements distributed over an arc in a longitudinal-transverse plane;
an actuator contained in the housing for rotating the imaging sensor, about said longitudinal axis, relative to the housing; and
an imaging circuit arranged to capture and process data of the imaging sensor.
