Abstract: The present invention relates to an adaptive medical image transmission device and method which consider communication state and residual power. The adaptive medical image transmission method induces an image receiving device to post-process a result of medical image processing performed by a medical image transmission device by: receiving medical image data by means of a probe; sensing communication throughput indicative of a communication state between the image transmission device and the image receiving device; variably determining a data rate required to transmit data on the basis of a preset data rate based on the sensed communication throughput; performing medical image processing by selecting a signal path which satisfies the determined data rate with respect to the medical image data; and transmitting the result of the medical image processing to the image receiving device according to the determined data rate.

Abstract: An ultrasound diagnosis apparatus includes: a controller configured to obtain a real-time scan image based on ultrasound data about a region of interest, determine whether a movement of a probe occurs based on the ultrasound data, and when the movement of the probe does not occur for a first time or more, obtain an ultrasound still image in which at least one image quality parameter according to a preset standard is changed based on the ultrasound data; and a display configured to display the real-time scan image and the ultrasound still image.

Abstract: User interaction is provided for a medical imaging system. The user interacts with the display rather than programmed buttons. The context between the user input and the display, such as identifying user selection of a bottom edge of a displayed image, is determined. The imaging system is controlled based on the context, such as altering the depth of imaging as the user drags the selected bottom edge up or down on the screen.

Abstract: Disclosed herein is a method for the optimal design of an apodization function used for non-uniform weighted periodic sparse arrays for an ultrasound imaging system. The method includes the steps of (a) setting the interval PT of a transmit sparse array and the number LT of array elements within the interval PT so that common grating lobes are not generated in the beam patterns of the transmit sparse array and a receive sparse array; (b) setting the interval PR of the receive sparse array and the number LR of array elements within the interval PR so that common grating lobes are not generated in the beam patterns of the transmit sparse array and the receive sparse array; (c) setting a transmit apodization function WT(n) configured to be applied to the beam pattern of the transmit sparse array; and (d) setting a receive apodization function WR(n) configured to be applied to the beam pattern of the receive sparse array.

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.
