Ultrasonic diagnostic apparatus and method of controlling a ultrasonic diagnostic apparatus

A method of controlling an ultrasonic diagnostic apparatus which scans a predetermined region of a subject with a contrast medium injected, by using an ultrasonic probe, and which generates an ultrasonic image, said method comprising:

• supplying drive signals to said ultrasonic probe to switch at least three wave transmitting conditions for acquiring distribution information on the contrast medium in tissues in said predetermined region, in a predetermined order by said ultrasonic scanning, the at least three wave transmitting conditions showing different contrast medium destructing abilities respectively;
• and
• generating an ultrasonic image from a reflection wave obtained from at least one of the ultrasonic waves transmitted respectively in each of the at least three wave transmitting conditions.

A memory storing computer-executable program code for controlling an ultrasonic diagnostic apparatus which scans a predetermined region of a subject with a contrast medium injected by using an ultrasonic probe, and which generates an ultrasonic image, said program code comprising:

• first means for causing a computer to supply drive signals to said ultrasonic probe to switch at least three wave transmitting conditions in a predetermined order, each of the at least three wave transmitting conditions being for acquiring distribution information on the contrast medium in the tissues of said predetermined region and showing different contrast medium destructing abilities;
• and
• second means for causing a computer to generate an ultrasonic image from a reflection wave obtained from at least one of the ultrasonic waves transmitted respectively in each of the at least three wave transmitting conditions.
