摘要： An X-ray imaging system includes an X-ray generator, an electronic cassette, a holder arm, a PC, and a control device. The holder arm has an L-shaped arm body and a base column. To one end of the arm body, an X-ray source is attached. The base column is perpendicularly attached to the electronic cassette, and swingably holds the arm body. The X-ray source is shifted among an R irradiation position, an L irradiation position, and a base position by the swing of the arm body, and is fixed at each position. With the shift of the X-ray source between the R and L irradiation positions, a parallax image including a pair of R and L viewpoint images is captured.
