1. A system for imaging an interior body region comprisinga probe including an axis and an imaging structure having a periphery adapted to selectively assume an expanded geometry and a collapsed geometry, andan array of spaced apart ultrasound transducers attached to the periphery of the imaging structure, wherein members of the array move radially outward and inward relative to the axis as the periphery assumes the expanded geometry and the collapsed geometry respectively.
