Patent ID: 7824336

Claim:
An ultrasonic apparatus for a diagnosis and therapy comprising: a first ultrasound probe configured to generate an ultrasound wave for a phase shift; a second ultrasound probe configured to generate an ultrasound wave for a diagnosis; a third ultrasound probe configured to generate an ultrasound wave for a therapy; an echo detection device configured to detect an ultrasound echo; a first control part configured to cause the phase shift in a nano droplet ultrasound contrast agent by exposing said ultrasound for the phase shift through said first ultrasound probe; a second control part configured to detect the phase shift of said ultrasound contrast agent using a nano droplet ultrasound echo detected by said echo detection device based on an exposure of said ultrasound for diagnosis by said second ultrasound probe; a difference calculation device configured to calculate a difference over time of said phase shift detected by said second control part for the diagnosis; a positioning device configured to decide a target position where said difference is produced; and a third control part configured to expose said ultrasound for the therapy to said decided target position through said third ultrasound probe; wherein said first ultrasound probe is further configured to generate the ultrasound wave including a first wave and a second wave, and wherein the first ultrasound probe is further configured to generate the second wave after the first wave and having an acoustic density which is not more than that of said first wave.
