Ultrasonic imaging method and ultrasonic imaging apparatus

摘要

Since a number of ultrasonic beams which are transmitted within unit time is increased, an ultrasonic imaging method is capable of obtaining image information in a high frame rate or improving resolution of the image information. In an ultrasonic imaging method of transmitting an ultrasonic beam toward a measurement target located within an object, receiving an ultrasonic echo and processing detection signals to obtain image information, there are provided with the steps of: (a) executing a pre-imaging operation and setting a region with respect to the measurement target on the basis of an image obtained by the pre-imaging operation; and (b) transmitting an ultrasonic beam in such a manner that the region set in step (a) is scanned and receiving an ultrasonic echo so as to execute an ultrasonic imaging operation.
