By the way, there is a device that performs sector scanning by arranging transducers in an array and giving a delay time to each transducer of the probe to deflect and scan the ultrasonic beam. be. However, in such a device, a precise delay circuit is required for each vibrator in order to deflect the ultrasonic beam, making the device expensive. It also has the disadvantage that uniform image quality cannot be obtained as sectors are scanned over a wide area.
