<p><P>PROBLEM TO BE SOLVED: To provide an installing structure for a QC phantom by which the QC phantom can surely be installed at a specified position of a receiving medium. <P>SOLUTION: In the installation system for installing the QC phantom which inspects the quality of an X-ray photographing system in the X-ray photographing system, a positioning means is installed. In this case, the positioning means positions the QC phantom and the receiving medium which receives a penetration X-ray level penetrating the QC phantom in two directions in such a manner that the QC phantom and the receiving medium may correspond to each other at specified positions. For example, the receiving medium is an accumulative fluorescent material sheet which records the penetration X-ray level, or a flat panel device which converts the penetration X-ray level into an electric signal. For the positioning means, at least two positioning pins which position the QC phantom at a position corresponding to the receiving medium are projected. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
