  • Coil, a method of construction of said coil and an imaging device equipped with a coil of this type
    Patent number: 5032764
    Abstract: In order to compensate for the influence of magnetic fields on charged-particle beams, in particular in imaging devices provision is made for a coil constituted by a support plate of substantially constant thickness and by patterns deposited on the support in such a manner as to ensure that the absorption of electromagnetic energy is constant over the entire surface of the coil within a predetermined pass-band.In a first embodiment, the patterns are transparent to the electromagnetic energy of a desired frequency band. In a second embodiment, complementary patterns are employed in order to obtain constant absorption over the entire surface of the coil.

  • X-ray image intensifier tube with circuit to compensate for the effects fo magnetic distortion
    Patent number: 4945223
    Abstract: To compensate for the effects of magnetic distortion in an X-ray image intensifier tube, the mode of scanning the target of the television camera associated with this tube is modified. Shifts, corresponding to measured distortions, are caused in the line scan and the vertical scan. In this way, an image which can be used in morphometry is restored on a display screen.
