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.

Method and apparatus for producing a three-dimensional moving image

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.

Three-dimensional ultrasound imaging system for performing receive-focusing at voxels corresponding to display pixels

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.

Ultrasound imaging system for performing receiving focusing at points corresponding to display pixels and method thereof

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.

Ultrasound imaging apparatus and method using Golay codes with orthogonal property

A refrigerator including a plurality of chambers and door shutters which are suspended on guide rails disposed under chamber partitions for slidably moving to open or close the chambers. The door shutters may be made of a flexible transparent material such as plastic or the like.
