AN ULTRASONIC IMAGING APPARATUS, AN ULTRASONIC PROBE APPARATUS, A SIGNAL PROCESSING APPARATUS AND A METHOD FOR CONTROLLING THE ULTRASONIC IMAGING APPARATUS

摘要

The purpose of the present invention is to provide a signal processing device capable of effective reducing noises of an image caused by a gap between individual elements in a device in which the individual elements output a signal. The present invention relates to an ultrasonic photographing device, a control method thereof, an ultrasonic probe device, and the signal processing device. The ultrasonic photographing device can comprise: one or more first ultrasonic elements installed in a first ultrasonic element installation unit; one or more second ultrasonic elements which are installed in a second ultrasonic element installation unit separated from the first ultrasonic element installation unit and forms a gap with the first ultrasonic elements; and a processor to estimate one or two or more virtual ultrasonic signals corresponding to the gap based on a first ultrasonic signal outputted from the first ultrasonic elements and a second ultrasonic signal outputted from the second ultrasonic elements.
