1. An ultrasonic diagnosis apparatus, comprising:
- an ultrasonic probe for transmitting/receiving an ultrasonic wave to/from a specific portion within a subject to be diagnosed to whom a contrast medium has been introduced;
a driving signal generator for generating a driving signal of said ultrasonic probe; and
a controller for controlling said driving signal generator in such a manner that said ultrasonic probe transmits a first ultrasonic wave used to destroy bubbles of said contrast medium and a second ultrasonic wave used to destroy at least part of bubbles each which substantially has a size larger than a size of each of the bubbles destroyed by said first ultrasonic wave and are flowing in blood in a blood vessel within said subject to be diagnosed.

Abstract
In transmissions of each frame through intermittent transmissions, by performing ultrasonic wave transmissions while increasing a mechanical function step by step, destructions of bubbles of a contrast medium can be induced step by step according to their different sizes. By generating ultrasonic images using the destructions at the respective steps as the sources of echoes, it is possible to provide new ecological information including, for example, information reflecting the dynamics of substances smaller than the red blood cells, the distribution of predatory cells, new diagnosis information, etc.

- 10. A method of controlling an ultrasonic diagnosis apparatus for controlling a driving signal generator in such a manner that an ultrasonic probe, which transmits/receives an ultrasonic wave to/from a specific portion within a subject to be diagnosed to whom a contrast medium has been introduced, transmits a first ultrasonic wave used to destroy bubbles of said contrast medium and a second ultrasonic wave used to destroy at least part of bubbles each of which substantially has a size larger than a size of each of the bubbles destroyed by said first ultrasonic wave and are flowing in blood in a blood vessel within said subject to be diagnosed.
