  • Publication number: 20130261449
    Abstract: An ultrasound diagnostic apparatus includes a monitor displaying an ultrasound image, an operating unit receiving an operating instruction from an operator and a control unit controlling a diagnostic apparatus body. The control unit causes measurement calipers each having a measurement line extending linearly in a vertical direction and a gate portion including an upper gate line and a lower gate line which are disposed parallel to each other on the measurement line to be displayed in a superimposed manner on the ultrasound image displayed on the monitor based on the operating instruction from the operating unit, and measurement is sequentially performed at more than one measurement site using the gate portion of each of the measurement calipers which is capable of rotation and change of the distance between the upper gate line and the lower gate line.

  • Patent number: 8535231
    Abstract: An ultrasonic diagnostic apparatus is provided with an ultrasonic probe, an ultrasonic image generating section, a head mounted display (HMD), and an orientation measurement section. The ultrasonic probe has two-dimensionally arranged ultrasonic transducers. The ultrasonic image generating section generates a 2D ultrasonic image representing a cross section of a three-dimensional area inside of a patient's body. 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.

  • Publication number: 20120238877
    Abstract: An ultrasound diagnostic apparatus includes: a convex type ultrasound probe including a transducer array with a curvature; an image producer for producing a B mode image based on reception data; an abdominal wall detector for detecting an abdominal wall of the subject on the B mode image; a controller for obtaining reception data for a sound speed map by transmitting and receiving ultrasonic beams for a sound speed map through the transducer array by convex scan when a shape of the abdominal wall substantially corresponds to the curvature of the transducer array and by transmitting and receiving ultrasonic beams for a sound speed map through the transducer array by linear scan when the shape of the abdominal wall is substantially linear; and a sound speed map producer for producing a sound speed map based on the obtained reception data for a sound speed map.

  • Publication number: 20120226164
    Abstract: 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.

  • Publication number: 20120095339
    Abstract: An ultrasound diagnostic apparatus includes an ultrasound probe, an image producer, a monitor, a position designating unit for designating a target position when paracentesis is performed, an insertion position calculating unit for calculating an insertion position from information on the target position designated by the position designating unit and a predetermined insertion angle and an insertion position display unit for displaying the insertion position calculated by the insertion position calculating unit. The ultrasound diagnostic apparatus ensures that a puncture needle inserted from a position away from an ultrasound probe to reduce the insertion angle so as to be imaged at a higher definition can also reach a target site.

  • Publication number: 20120078103
    Abstract: 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.

  • Publication number: 20120035477
    Abstract: An ultrasound image having a good image quality is generated in the neighborhood of a puncture needle without lowering the image quality of the whole ultrasound image. A first echo signal received by transmitting first ultrasonic waves focused on an imaging target position and a second echo signal received by transmitting second ultrasonic waves having the depth of the focal point positioned at a uniform position are obtained, the weights of the first echo signal and the second echo signal are determined according to the focal point positions of the respective ultrasonic waves, and weighted addition is performed to generate a corrected image.
