ULTRASONIC DIAGNOSTIC APPARATUS AND IMAGE CONSTRUCTION METHOD

摘要

An ultrasonic diagnostic apparatus is provided with: an ultrasonic probe which is brought into contact with an object to transmit and receive ultrasonic waves; a transmission unit and a reception unit which periodically transmit and receive the ultrasonic waves to and from the object and subject a reflection echo signal from the object to reception processing; a displacement measurement unit which sequentially finds the displacements of a living organism tissue at the position of cross section at which the ultrasonic waves are transmitted to and received from the object; an elasticity image construction unit which sequentially constructs the elasticity images of the living organism tissue; and a three-dimensional image construction unit which constructs a three-dimensional elasticity image.
