摘要:
An apparatus may include an ultrasonic receiver array, an ultrasonic transmitter and a control system capable of controlling the ultrasonic transmitter to transmit first ultrasonic waves in a first direction and to simultaneously transmit second ultrasonic waves in a second direction that is opposite the first direction. The control system may be capable of distinguishing first reflected waves from second reflected waves, the first reflected waves corresponding to reflections of the first ultrasonic waves that are received by the ultrasonic receiver array and the second reflected waves corresponding to reflections of the second ultrasonic waves that are received by the ultrasonic receiver array. The control system may be capable of determining first image data corresponding to the first reflected waves and of determining second image data corresponding to the second reflected waves.
