Claim Text:
1. An ultrasonic diagnostic apparatus comprising: an ultrasonic probe having transducers that transmit/receive ultrasonic waves; a computer including a processor and storage, pre-configured to implement operations including: transmitting ultrasonic waves to an object to be examined, via the ultrasonic probe; receiving reflected echo signals from the object; storing RF signal frame data based on the reflected echo signals received by the receiving, in the storage which includes: selecting at least a pair of the first and second series of the RF signal frame data stored in the first and second storage media, respectively, of the storage; calculating strain or elasticity modulus, based on the selected RF signal frame data from the selecting; constructing 2-dimensional elastic image frame data, based on the strain or the elasticity modulus obtained by the calculating strain or elasticity modulus; creating elastic volume data from plural sets of the 2-dimensional elastic image frame data from the constructing 2-dimensional elastic image frame data, by comparison of the first and the second series of the RF signal frame data obtained at a substantially same position of the ultrasound probe along the sweep line; and constructing 3-dimensional elastic image from the elastic volume data created by the creating.
