ABSTRACT:
An x-ray photographing apparatus includes a first x-ray image detecting unit having a first x-ray image detection region, a second x-ray image detecting unit arranged in tandem with the first x-ray image detecting unit and having a second x-ray image detection region, and a bed apparatus having a subject placing unit for moving a subject to be examined between the first and second x-ray image detection regions. The first x-ray image detecting unit performs x-ray film photography and fluoroscopy of the lower limbs of a subject to be examined. The second x-ray image detecting unit performs x-ray film photography of the entire region of the lower limbs of the subject. The bed apparatus serves to perform photography of a blood vessel with a contrast medium. The subject placing unit can arbitrarily perform moving and stopping operations between the first and second x-ray image detection region. In addition, the subject placing member can perform a continuous moving operation and a step moving operation between the first and second x-ray image detection regions.
