Abstract: 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; obtaining raw data; generating image frame data based on the obtained raw data; generating virtual image frame data based on the generated image frame data; and rendering 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.

Abstract: A method and apparatus for enabling a biopsy needle to be observed in a three-dimensional ultrasound diagnostic system using an interventional ultrasound system. The apparatus comprises an ultrasound transducer, a three-dimensional image-forming section, a section for extracting a target object, a location-calculating section, a display section, and a controller. The method comprises the steps of acquiring a two-dimensional ultrasound image of a subject; generating a three-dimensional volume image based on the two-dimensional ultrasound image; segmenting a target image, which corresponds to a target object within the subject, from the three-dimensional volume image; displaying a guide line of the biopsy guide on the segmented target image; extracting the segmented target image; acquiring information on a location of the biopsy needle by reference to the segmented target image; calculating an error based on the information; and displaying a guiding status of the biopsy needle based on the calculated error.

Abstract: A three-dimensional (3D) ultrasound imaging system performs receive-focusing at voxels corresponding to pixels of a display device. The system comprises a display device; transducers for transmitting ultrasound signals toward the object and receiving echo signals from a voxel corresponding to a pixel on the display device, wherein the voxel is on a scanning region of the object; an RF volume memory for storing signals from the transducers; a signal processor for processing the stored signals to obtain 3D data sets with respect to the voxel; and an image former for forming the 3D image.

Abstract: All RF data received by transducers in response to an ultrasonic signal that was transmit-focused on a point along a predetermined scan lines are stored to compute display data for those points of an object that do not necessarily correspond to the pixels of the screen of a display device. For the determination of display data for each pixel point, reflected ultrasonic signals from multiple points around the point of interest are found and used to detect the peak of a waveform constituted by the reflected ultrasonic signals. With this scheme, the distortion due to conventional interpolation used for a limited number of scan lines can be greatly reduced.

Abstract: Ultrasound images are obtained using a set of Golay codes with orthogonal property as ultrasound receiving and transmitting signals. Ultrasound signals having a plurality of codes are transmitted simultaneously by using the orthogonal property of the Golay codes. A superior signal-to-noise rate (SNR) is realized using the Golay codes, without suffering a decrease in the frame rate.

Abstract: An ultrasonic diagnostic apparatus uses an ultrasonic wave to obtain information on the inner state of a human body without conducting a surgical operation on the patient. The ultrasonic diagnostic apparatus includes a receiving recess so that a patient-use monitor can be connected with and disconnected from a main body. Diagnostic results measured in the main body are displayed on the patient-use monitor including a support shaft which can be inserted into the receiving recess. Thus, the patient can see his or her diagnostic results easily. Since the patient-use monitor is compatible with other types of ultrasonic diagnostic apparatuses having each receiving recess installed in the main body, the patient-use monitor can be used in other types of the ultrasonic diagnostic apparatuses.
