A multi-plane imaging transducer generates a plurality of planes of image data from the ultrasound echo information including at least a first plane, a second plane orthogonal to the first plane, and a third plane orthogonal to the first and second planes. The multiplane imaging transducer may further generate a transverse view, sagittal view, and coronal view from derived from previously stated image planes. The transducer is used in association with a guidewire inside a superficial artery, such as the superficial temporal artery. The guidewire has a distal end formed into a knob and has a bend for steering through the artery. The knob is used to allow snaring for mechanical engagement from a femoral artery catheter.
