<p><P>PROBLEM TO BE SOLVED: To provide an X-ray measuring apparatus capable of correcting nonuniformity caused by a filter and providing a favorable three-dimensional image. <P>SOLUTION: This X-ray measuring apparatus is provided with an X-ray source 101 generating X-rays irradiating an examinated object 108, an X-ray detector 102 detecting measurement data on the examinated object 108, a retainer 103 retaining the opposed X-ray source 101 and the X-ray detector 102, a rotating device 104 changing the relative position of the X-ray source 101 and the X-ray detector 102 to the examined object 108, and a control processor 106 computing the measurement data. This apparatus is characterized in that a filter 110 having a cross sectional shape formed by combining a recessed arc, a projecting arc and a straight line together is installed between the X-ray source 101 and the examinated object 108, and while the rotating device 104 rotates, the X-ray source 101 generates the X-rays and the X-ray detector 102 collects the measurement data. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
