Abstract: PURPOSE: A method and an apparatus for estimating an ultrasonic speed by using the size of channel data are provided to minimize phase distortion by using a scan change and a beam concentration. CONSTITUTION: A conversion element unit(510) generates channel data according to each channel. A beam former(520) concentrates a beam by using a received ultrasonic speed. An intermediate processor(530) detects an envelope signal about a beam concentration signal. A back end processor(540) displays a log compression result on a screen. A channel data capturing unit(550) captures the channel data in an interest area.

Abstract: PURPOSE: A method for producing an ultrasonic wave video using a concave array is provided to secure a desired image width by designing an ultrasound transducer in a concave form. CONSTITUTION: The array of a concave form which consists of one or more ultrasonic transducers is placed on a cornea. An ultrasonic image generated using the ultrasonic wave which is transmitted and received through the array of the concave form. A generated ultrasonic image is displayed. The focusing point of the array of the concave form is placed on a vitreous humor. The focusing point of the array of the concave form is placed on the vitreous body of an eyeball in a state where the array of the concave form is placed on an eyelid. The ultrasonic image belongs to the image of the posterior segment of the eyeball.
