<P>PROBLEM TO BE SOLVED: To acquire a stereoscopic image suitable for stereoscopic vision without causing a cost increase and to perform stereoscopic imaging of excellent stability and reproducibility. <P>SOLUTION: An imaging apparatus includes a radiation irradiating section for irradiating a subject with radiation from two mutually different imaging directions, and a radiation image detector for detecting radiation images for every imaging direction with the irradiation of radiation of the radiation irradiating section. The mammographic imaging apparatus acquires two radiation images detected by the radiation image detector, as images that compose the stereoscopic image. Radiation in two imaging directions is emitted from a first focal position of a first radiation source 17a and from a second focal position of a second radiation source 17b, and each of the first and second radiation sources 17a, 17b includes a field emission type electron source that generates electrons by applying an electric field, and a positive pole for emitting radiation by the incidence of electrons. <P>COPYRIGHT: (C)2012,JPO&INPIT |
