Abstract:
An X-ray imaging apparatus includes: an X-ray source configured to irradiate X-rays to an object; an X-ray detector configured to obtain a first X-ray image of the object; a noise-reduced image creator configured to generate a noise-reduced image in which a noise is reduced from the first X-ray image; a noise image creator configured to generate a noise image based on differences between the first X-ray image and the noise-reduced image; an edge image creator configured to generate, from the noise image, an edge image in which edges are enhanced; an output image creator configured to combine the noise-reduced image with the edge image to generate a second X-ray image; and a display configured to display the second X-ray image. By enhancing edges while reducing noise, an image with high definition and high quality may be output and a user can obtain accurate information from the image.
Abstract:
The X-ray imaging apparatus includes an X-ray generator to generate and emit X-rays, an X-ray detector to detect the emitted X-rays and acquire X-ray data, and a controller to convert the X-ray data into X-ray characteristic coordinates and estimate a response characteristic function of the X-ray detector from a relationship between measurement data and reference data, the measurement data and the reference data being converted into the X-ray characteristic coordinates.
Abstract:
Disclosed are a portable terminal with a music performance function and a method for playing a variety of musical instruments. The method includes: selecting a particular piece of music and a particular musical instrument from the portable terminal, according to a user request, and executing a music performance mode corresponding to the selected musical instrument; detecting a first input signal input to a screen according to the selected musical instrument in the musical performance mode; determining, if the first input signal is detected, whether a second input signal for executing audio source data is detected; analyzing the first and second input signals, in association with each other; and outputting audio source data of the selected music, according to the analyzed result, via audio signals.

Abstract:
Disclosed herein are an X-ray imaging apparatus for providing information about accurate breast density, and a control method of the X-ray imaging apparatus. The X-ray imaging apparatus includes a reconstructing unit configured to reconstruct volumes relating to an object from an X-ray image of the object, a first reference image of the object generated based on the object being of only adipose tissue, and a second reference image of the object generated based on the object being of only fibroglandular tissue, and a density calculator configured to calculate a density of the object that is a ratio of fibroglandular tissue of the object with respect to entire tissue of the object using the reconstructed volumes of the object.
Abstract:
An X-ray imaging apparatus and method for controlling the X-ray imaging apparatus are provided. The X-ray imaging apparatus includes an X-ray source configured to generate and emit X-rays onto an object, an X-ray detector configured to detect the X-rays transmitted through the object and convert the X-rays into an electrical signal, a heating portion located at an upper portion of the X-ray detector configured to contact a lower part of the object, a heat transfer portion configured to transfer heat produced in the X-ray source to the heating portion, and a thermal insulation member located between the X-ray detector and the heating portion configured to block heat from being transferred to the X-ray detector.
Abstract:
Provided is an apparatus for spectrum estimation. The apparatus includes a threshold setter which sets at least one threshold in order to separate a spectrum into at least one energy bin; a reference value setter which sets one of the at least one threshold as a reference threshold; a threshold adjuster which adjusts the at least one threshold based on a predetermined condition; a comparer which compares the reference threshold with the adjusted threshold; and an output unit which outputs a spectrum in which the adjusted threshold is set, when a value which is determined based on the comparison result corresponds to a predetermined maximum value.
