    摘要： An ultrasonic probe issues an ultrasonic wave to an object, receives a reflected wave from an object, and is provided with multiple piezoelectric elements. A three-dimensional display section displays three-dimensional flaw detection data superimposed on three-dimensional shape data of an object. The computer acquires a reflected ultrasonic wave signal from a reference object (reference). Based on the acquired signal, the computer corrects a reflected ultrasonic wave signal acquired from another object having the same material and shape as the reference. The computer allows the three-dimensional display section to display three-dimensional flaw detection data generated from a reflected ultrasonic wave signal resulting from a difference between a reference and an object.

    摘要： Disclosed is an apparatus and method for producing a three-dimensional (3D) moving image of a moving target object. The method comprises the steps of transmitting and receiving ultrasound signals to / from the moving target object (S202), obtaining raw data (S204); generating image frame data based on the obtained raw data; generating virtual image frame data based on the generated image frame data; and rendering (S206) a 3D moving image of the moving target object using the image and virtual image frame data. The apparatus comprises a probe, a raw 3D data obtaining unit, and an enhanced live 3D imaging unit for producing a 3D image of the moving target object.

    摘要： The invention relates to a method for recording ultrasound images of moving objects (1), according to which an ultrasound transmitter transmits ultrasound onto the object (1) and an ultrasound receiver receives the ultrasound reflected by the object (1). A data processing system (4) detects and stores the received ultrasound and the corresponding movement state of the object (1). The ultrasound transmitter and ultrasound receiver are moved alongside the moving object (1) and produce images of individual partial image areas (9) of the object (1). At those moments when the movement of the object is greatest, no or only few images are taken. When the object moves only little several images of individual partial image areas (9) of the object (1) are taken and/or analysed. By assigning the individual partial image areas (9) to the corresponding movement states of the object (1) either selective individual movement states or entire movement sequences of the object (1) can be shown in real time. The method provided for by the invention is especially suited for taking images of the blood vessels of an organism, whereby the exact moments when the individual partial image areas (9) of the blood vessel are recorded are controlled by the electrocardiogram of the organism.

    摘要： A flow display method enabling the state of flows in a plane to be grasped together with inflow into and outflow from that plane. A Doppler method, for example, is used to obtain a velocity profile at each point in a planar area (100) of interest defined in a three-dimensional flow. A flow rate profile in the planar area (100) is found on the basis of the thus obtained velocity profile. From the flow rate profile and the velocity profile there are determined source points (12) representative of inflow into the planar area (100) and sink points (14) representative of outflow therefrom. Contour lines in the flow rate profile then join the source points (12) and the sink points (14) to obtain a display of planar streamlines (10).

    摘要： A three-dimensional imaging system for obtaining a three-dimensional image of an object (20) being scanned ultrasonically comprises a source arrangement (SA) for sequentially transmitting ultrasonic energy toward the object in successive directions in a first scanning plane, followed by sequential transmission of ultrasonic energy toward the object in successive directions in successive scanning planes parallel to the first scanning plane, a detector arrangement (DA) for receiving reflected energy and converting the reflected energy to electrical signals, and a processor (72) for processing the electrical signals to develop reconstructed image data comprising forward projections of the object into a left image plane and a right image plane to form left and right images, respectively, the left and right images forming a stereo pair of composite display by a display unit (74).
