Abstract
Provided is a measuring apparatus, including: a moving mechanism for moving a probe in an elevation direction; a first delay and sum circuit for performing delay and sum of reception signals at individual positions along the elevation direction to output a first add signal; a signal extraction circuit for letting an output of the first delay and sum circuit to pass through delay circuits to output in parallel first add signals obtained at different positions; a second delay and sum circuit for performing delay and sum of the first add signals output from the signal extraction circuit to output a second add signal; and an image processing circuit for generating image data by using the second add signal. Accordingly, image resolution in the elevation direction may be improved with a simple structure without deteriorating an image obtaining speed in the measuring apparatus for obtaining an ultrasonic image.
