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 |
