The present invention comprises: a first X-ray irradiation apparatus and a second X-ray irradiation apparatus for irradiating a subject with X-rays; an X-ray generation unit supporting so that first and second X-rays irradiated onto the subject are detected by a set detector when the subject is irradiated with the first and second X-rays from the first and second X-ray irradiation apparatuses, respectively; and a mode selection unit for allowing selection of any one mode from among a 2D imaging mode and 3D imaging mode, wherein the angles with respect to the subject of the first and second X-ray irradiation apparatuses are determined on the basis of said any one mode selected by means of the mode selection unit from among the 2D imaging mode and 3D imaging mode. According to the present invention, the mode can be easily selected according to need from among the 2D imaging mode and 3D imaging mode.

Disclosed are an electrochemical biosensor which comprises a production lot information identification portion, on which information is recorded in a magnetization mark, and a measuring device which can automatically identify the production lot information of the biosensor with the insertion of the electrochemical biosensor into the measuring device. The electrochemical biosensor and the measuring device thereof can record production lot information in the form of magnetization marks on an electrochemical biosensor strip and read the information as digital signals through a magnetoresistance sensor device, which can be mounted on the surface of a circuit board using Surface Mounted Technology (SMT). Without the need for a high-priced filter or a complicated calculation system, the magnetic detector system has a simple construction and realizes economic efficiency in the construction of the measuring device. Also, the measuring device automatically identifies the production lot information recorded on the biosensor, so that inconvenience and the frequency of errors, which occur when a user personally inputs the production lot information, can be reduced, with the result that the measured values can be conveniently and accurately acquired.
