Abstract:
An X-ray diagnostic apparatus comprising:an X-ray source which emits an X-ray beam; a storage luminescent screen on which said X-ray beam is incident for storing a latent X-ray image produced by said X-ray beam; a readout system having a source of stimulating radiation for exciting said storage luminescent screen to luminescence, and having a light detector for acquiring light emitted by said storage luminescent screen; an image playback system supplied with signals representing said light from said detector for converting said signals into a displayable visual image corresponding to said latent X-ray image; and said readout system including a supporting structure having an opening with a rectangular cross-section through which said storage luminescent screen is guided for scanning said storage luminescent screen with said stimulation radiation, said supporting structure having a scanning region containing a plurality of air bearings disposed on opposite sides of said opening for holding said storage luminescent screen in said scanning region, and said radiation source and said light detector being line-shaped and mounted to said supporting structure.
