The present disclosure relates to a system and a method for providing personal information for an online service system. More particularly, the present disclosure relates to a system and a method for providing personal information using a one-time private key based on a blockchain of proof of use, wherein personal information is registered and stored in a distributed manner in a blockchain network, services in online and offline service systems are used by using alternative authentication identification information that is anonymous and includes a public key to access the personal information in the blockchain network, and for membership registration and login, only the alternative authentication identification information is used to receive a service, become a member of a service, and to log in, without providing the personal information.

A computed tomography (CT) image processing apparatus and a CT image processing method are provided. The CT image processing apparatus may generate a virtual monochromatic image (VMI) by applying a weight to each of first, second, and third images corresponding to three different energy ranges. The CT image processing apparatus may set a region of interest (ROI) on a CT image, determine a VMI at an energy level at which a CNR of the ROI is at a maximum among a plurality of VMIs, and display the determined VMI.

Tomographic image processing apparatus and method

A tomography imaging apparatus and a tomography imaging method are provided. The tomography imaging apparatus includes a data acquirer configured to acquire first X-ray data of an object for each of energy bands, and an image preprocessor configured to perform a beam hardening correction on the first X-ray data for each of the energy bands, to generate second X-ray data of the object. The tomography imaging apparatus further includes an image reconstructor configured to reconstruct a tomography image of the object based on the second X-ray data.

Disclosed herein is a flexible self-expandable stent using shape memory alloy for expanding stenosal portions and method and apparatus for fabricating the same. The self-expandable stent using shape memory allow, comprises a first cylindrical stent member comprised of a first wire formed of super elastic shape memory alloy, the first wire being bent a large number of times while being extended upwardly and downwardly a large number of times, so the first wire forms a plurality of variable rhombic spaces by forming a plurality of intersections for causing the first wire to be intersected with itself to resist longitudinal constriction of the first cylindrical stent member and a plurality of interlocked points for causing the first wire to be interlocked with itself at spaced positions to allow longitudinal constriction of the first cylindrical stent member; and a second cylindrical stent member comprised of a second wire formed of super elastic shape memory alloy, the second wire being diagonally extended in parallel with the previously positioned first wire and passed alternately under and over the first wire so as to divide each of a plurality of rhombic spaces formed in the first cylindrical stent member into four equal parts, thereby preventing the first and second cylindrical stent members from being separated from each other.
