An ultrasound contrast medium which substantially consist of microbubbles is injected into a patient and contrast echo imaging is performed by a diagnostic ultrasound apparatus. In the apparatus, an ultrasound pulse signal is transmitted toward the patient's diagnostic region on the basis of a changeable transmitted sound pressure, an echoed component of the transmitted ultrasound pulse signal is received to produce a corresponding reception signal, a tomographic image using the reception signal is produced, and the transmitted sound pressure is optimized so as to maximize a value of the reception signal. The transmitted sound pressure is a representative of the transmission power condition. For example, the transmitted sound pressure optimized is displayed. The transmitted sound pressure is, by way of example, optimized based on the reception signal corresponding to the echoed component emanating from an overall region of interest in a cross section scanned by the ultrasound pulse signal.
