摘要： An echo signal reflected from a microbubble contrast agent is discriminated from an echo signal generated upon reflection of a nonlinearly propagated transmission pulse from the body tissues without degradation of the axial resolution, by performing transmission/reception twice or less which would hardly decrease the imaging speed. By detecting a difference in phase of the second harmonic component based on the fundamental component included in the echo signal, an echo signal generated upon nonlinear reflection from a microbubble contrast agent is discriminated from an echo signal generated upon linear reflection of a nonlinearly propagated transmission pulse from the body tissues. The phase of the second harmonic component is detected through phase sensitive detection in which the square of the fundamental component is used as a reference wave. Concurrently, a pulse inversion method is used to extract the second harmonic component included in the original echo signal, whereby degradation of the axial resolution is prevented.

摘要： An ultrasonic apparatus for diagnosis and therapy is provided with plural ultrasound probes for generating ultrasound waves for phase shift, diagnosis, and therapy. A first control part causes phase shift in a nano droplet ultrasound contrast agent, while a second control part detects the phase shift of the nano droplet ultrasound contrast agent using ultrasound echo detected by an echo detection device. A difference calculation device calculates a difference of the detected phase shift over time, and a positioning device determines a target position where the difference is produced. A third control part is also provided for exposing a decided target area to the ultrasound waves for therapy.

摘要： An identification apparatus that keeps the conditions for imaging uniform among successive identifications and requires a user to perform only a series of simple maneuvers. An identification apparatus comprising a guide member, a light source, and an imaging unit. The guide member includes a pattern or a structure that inspires a user to position his/her finger thereon or to approach his/her specific finger region thereto. A contact member such as a button switch is preferably located at a position in the guide member at which a fingertip is to be positioned. An optical opening is formed at a position coincident with a position at which a portion of a finger to be imaged for identification should be placed. The light source radiates near-infrared light through the portion of the finger to be imaged. The imaging means acquires an image of the finger, and the apparatus compares the image to previously registered images. The apparatus may also include dual light sources power saving functionality, and means for limiting the interference of external light sources.
