摘要： The ultrasound diagnostic apparatus, ultrasound image generation apparatus and method transmit ultrasound waves to a subject into which a puncture tool is inserted, receive reflected waves reflected from the subject and the puncture tool, and generate echo signals of time-sequential frames based on the received reflected waves, and generate an ultrasound image of the subject based on the generated echo signals. These apparatus and method generate a differential echo signal between time-sequential frames from the echo signals, perform a tip detection process based on the differential echo signal to thereby detect at least one tip candidate including a tip end of the puncture tool, highlight a tip candidate of the puncture tool detected to thereby generate a tip image, and display the tip image of the highlighted puncture tool so as to be superimposed on the generated ultrasound image.

摘要： An ultrasound diagnostic apparatus includes plural ultrasound transducers which perform transmission and reception of ultrasonic waves toward a target site of a subject containing a puncture needle. A method of transmitting and receiving an ultrasonic wave uses the ultrasound transducers. The apparatus and the method form an ultrasonic beam to be transmitted from a transmit aperture set on the ultrasound transducers, acquire information relating to a specular-reflective component of the ultrasonic beam in the puncture needle, set a first receive aperture different from the transmit aperture set on the ultrasound transducers on the basis of the information relating to the specular-reflective component of the ultrasonic beam, and process an ultrasonic echo signal received by the ultrasound transducers using the first receive aperture.

The HMD has an orientation sensor for outputting signals corresponding to motion of the HMD and a projector for projecting images and the like within the view of an operator Op. The orientation measurement section measures rotation direction and rotation angle of the operator Op's head (HMD). A plurality of cross sections of the three-dimensional area inside of the patient's body for which the 2D image is generated is preliminary set, and the generated 2D ultrasonic image is switched according to the rotation direction and the rotation angle of the HMD.
