ULTRASOUND WAVE OBSERVATION APPARATUS, ULTRASOUND WAVE OBSERVATION APPARATUS OPERATION METHOD, AND ULTRASOUND WAVE OBSERVATION APPARATUS OPERATION PROGRAM

摘要

To provide an ultrasound wave observation apparatus that allows observation at high luminance without the contrast medium being destroyed.SOLUTION: The ultrasound wave observation apparatus transmits an ultrasound wave to a subject to which a contrast medium has been administered and generates an ultrasound image on the basis of ultrasound signals reflected by the contrast medium, the ultrasound wave observation apparatus comprising: an average luminance value calculation unit for calculating an average luminance value in a predetermined region, for each of a plurality of ultrasound images generated by transmitting an ultrasound wave at a constant sound pressure; a limit value calculation unit for calculating a limit value of the sound pressure of the ultrasound wave in which the contrast medium is not destroyed, based on the amount of variation in the average luminance value; and a control unit for control to limit the sound pressure of the transmitted ultrasound wave to the limit value or less.SELECTED DRAWING: Figure 1
