    摘要: Embodiments for forming elastic images in an ultrasound system are disclosed. In one embodiment, a Tx/Rx unit repeatedly transmits/receives an ultrasound beam along scan lines in a target object to output receive signals. An image processing unit forms a plurality of consecutive ultrasound images based on the receive signals and set a center of the target object on each of the ultrasound images. The image processing unit further sets radial scan lines in radial directions with respect to the center on each of the ultrasound image and reconstructs the ultrasound images such that the radial scan lines are in parallel with each other to form reconstruction images. An elastic image forming unit forms an elastic image based on the reconstruction images.

    摘要: There are disclosed embodiments for forming an enhanced elastic image in an ultrasound system. An elastic image of a target object may be formed by scanning N scan lines. A control unit divides the N scan lines into M scan lines groups by using an acquisition period necessary for transmitting and receiving ultrasound signals to acquire ultrasound data. An ultrasound data acquiring unit transmits ultrasound signals to a target object and receives the ultrasound signals reflected from the target object at a predetermined transmission/reception sequence for each of the M scan line groups. This forms ultrasound data corresponding to each of the M scan line groups while a pressure is applied to the target object. An elastic image forming unit forms at least one sub elastic image corresponding to each of the M scan line groups based on the ultrasound data. The elastic forming unit sums M sub elastic images corresponding to the respective M scan line groups to thereby form an elastic image of the target object.

    摘要: The present invention relates to an organic-transition metal complex which can safely and reversibly store hydrogen in a high capacity, and a process for preparing the same. In order to achieve the objects, the hydrogen storage material according to the invention comprises a complex generated by combination of an organic substance containing a hydroxyl (—OH) group(s) with a transition metal containing compound, which can more effectively store hydrogen with more than one transition metal being bonded per molecule. Examples of the organic substances containing hydroxyl (—OH) group(s) include alkyl derivatives such as ethylene glycol, trimethylene glycol and glycerol, and hydroxyl-containing aryl derivatives such as fluoroglucinol. As the transition metal, titanium (Ti), vanadium (V) and scandium (Sc), which can make Kubas binding, may be mentioned.

    摘要: In a method of compounding an ultrasound image, ultrasound signals having a transmission frequency are transmitted to a target object at a predetermined steer angle. Then, signals reflected by the target object are received. Based on the received signals, an image frame is formed. By repeating the above steps with different transmission frequencies, two or more image frames are obtained. The obtained image frames are then combined to provide a compound ultrasound image. The steer angle varies based on the transmission frequency.
