Abstract:
A method and apparatus for combining a three-dimensional (3D) model with a plurality of two-dimensional (2D) images by adjusting degrees of transparency of the plurality of 2D images. The method includes: obtaining a plurality of 2D images; arranging the plurality of 2D images in a 3D space based on predetermined criteria; obtaining spatial coordinates of each of the plurality of 2D images arranged in the 3D space; generating a 3D model of the plurality of 2D images arranged in the 3D space based on the spatial coordinates; changing attribute information of the plurality of 2D images arranged in the 3D space; and displaying the 3D model and the plurality of 2D images whose attribute information is changed.
Abstract:
Method and apparatus for measuring an object in a captured image. The method includes: receiving a captured image from a photographing apparatus; selecting a predetermined region on the received image based on a user input; magnifying an image with respect to the selected, predetermined region; obtaining brightness information of the received image; displaying at least one of the magnified image and the obtained brightness information; and selecting the object on the magnified image based on the obtained brightness information. The method may further include: obtaining pixel information of the received image; and measuring the selected object based on the pixel information.

Abstract:
Provided is a three-dimensional (3D) ultrasound system for intuitively displaying a change in motion and a method of operating the 3D ultrasound system. The 3D ultrasound system may include a scan unit to generate ultrasonic data of an object through scanning, a coordinate determination unit to determine first coordinates corresponding to a top end of the object, and second coordinates corresponding to a bottom end of the object, from the ultrasonic data, and a display control unit to measure a vector length from the first coordinates to the second coordinates, and to display a color corresponding to the measured vector length by mapping the color to the ultrasonic data.
Abstract:
The present invention relates to an ultrasound system and a method of setting an intima-media thickness (IMT) measuring region. The ultrasound system comprises an ultrasound diagnosis unit configured to transmit ultrasound signals to a target object, receive ultrasound echo signals reflected from the target object and form an ultrasound image including a plurality of pixels based on the ultrasound echo signals, each pixel having an intensity of gray level. The ultrasound system further comprises a processor configured to compute intensities of the pixels at each row in the ultrasound image to form a first graph, compute first moving averages of the intensities for first subsets of rows in the ultrasound image by dividing the intensities by a thickness of a blood vessel to form a second graph, compute second moving averages of the intensities for second subsets of rows in the ultrasound image by dividing the intensities by a thickness of a vascular wall to form a third graph, and set an intima-media thickness (IMT) measuring region by using inflection points from the second and third graphs.

Abstract:
The present disclosure relates to an ultrasonic diagnostic apparatus for providing a combination of an ultrasound image and a color flow image. The ultrasonic diagnostic apparatus detects a color index of each of pixels in a color flow image and provides a contour image composed of contour lines. Here, each of the contour lines is formed by grouping and connecting pixels having the same color index based on the detected color indexes of the respective pixels and formed for at least one color index level. A diagnosis method of the apparatus is also disclosed.
