Methods and devices for generating ultrasound images during a medical procedure are disclosed. The device (100) may comprise a shaft (102) that includes a working channel (230) for receiving an instrument, the working channel extending from a proximal end of the shaft to a distal end of the shaft, and an ultrasound sensor (150) disposed radially outward of a distal portion of the working channel such that the ultrasound sensor at least partially surrounds the working channel. The ultrasound sensor may be configured to image a single field of view greater than about 90 degrees about the shaft, e.g., simultaneously, while conducting a medical procedure with an instrument inserted through the working channel.
