| 20110158379 | COMPUTED TOMOGRAPHY SYSTEM HAVING NANO-SPATIAL RESOLUTION - Provide is a computed tomography (CT) system having a nano-spatial resolution. The computed tomography system can obtain a 3-dimensional image having the nano-spatial resolution of less than about 100 nm from a 2-dimension image generated by limiting a thickness of a bio sample such as cells and micro-tissues or an industrial solid sample such as a semiconductor chip to a thickness of less than about 100 μm, enlarging an X-ray transmitting the sample to a high magnification of greater than about 100× using a diffractive optic having a magnification of greater than about 100× such as a zone plate, and condensing the X-ray. When the CT system having the nano-spatial resolution is used, the 3-dimensional image having the nano-spatial resolution of less than about 100 nm may be obtained from the bio sample and industrial solid sample having a thickness of less than about 100 μm that is not observed using a conventional CT system including a cone-shaped light source unit. Therefore, an internal structure (an internal short-circuit of a semiconductor chip) of the sample may be very easily detected. | 06-30-2011 |
| 20100254510 | APPARATUS FOR DIAGNOSING BREAST CANCER BY NESTED FILTERS COATED MULTILAYER - Provided is a breast cancer diagnosing apparatus using an X-ray, in which the breast cancer diagnosing apparatus selects and uses energy within a specific band width through an energy band pass filter. In the breast cancer diagnosing apparatus, a multilayer filter unit having one or more layers of a basic filter having a multilayer structure is inserted between an X-ray generator and a breast fixing unit having a paddle fixing the breast so as to allow a predetermined band of an X-ray spectrum generated from the X-ray generator to pass therethrough and be emitted to the breast. According to the present invention, the X-ray dosage of the patient by energy within a low energy band (8-15 keV) can be reduced 5 times as compared with that by the conventional apparatus. | 10-07-2010 |
