Source Support Patents (Class 378/193)
  • Patent number: 7295648
    Abstract: A radiation therapy/surgery device optimised to meet the needs of the Neurosurgeon is provided, i.e. one for the treatment of tumours in the brain. It combines the qualities of a good penumbra and accuracy, simple prescription and operation, together with high reliability and minimal technical support. The device comprises a rotateable support, on which is provided a mount extending from the support out of the plane of the circle, and a radiation source attached to the mount via a pivot, the pivot having an axis which passes through the axis of rotation of the support, the radiation source being aligned so as to produce a beam which passes through the co-incidence of the rotation axis and the pivot. It will generally be easier to engineer the apparatus if the rotateable support is planar, and more convenient if the rotateable support is disposed in an upright position. The rotation of the rotateable support will be eased if this part of the apparatus is circular.

  • Patent number: 7286645
    Abstract: An x-ray device includes an x-ray tube for generation of an x-ray emanating from a focal spot of a rotary anode rotatable around a rotation axis and a slit-shaped diaphragm for generation of a fan-shaped x-ray beam that is gated from the x-ray and emission is moved through an examination region in the manner of a scan. To improve the image resolution, the fan-shaped x-ray beam can be moved over the examination region essentially in the direction of the rotational axis of the rotary anode by tilting the x-ray tube on the focal spot, with the x-ray tube being tilted on the focal spot so that the fan-shaped x-ray beam is always gated from the region of the overall emitted x-ray beam having the highest image resolution or the highest image definition in the movement through the examination region.

  • Patent number: 7277527
    Abstract: A technique is disclosed for presenting a sample to a radiation interface of an analysis engine employing x-ray, neutron ray, gamma ray or particle-beam radiation to analyze the sample. A protective barrier, transparent to the radiation, and separating the sample from the engine, is moveable relative to the radiation interface, using a barrier movement system. The barrier in one embodiment is a film movable over a cavity in which the sample placed, and moveable with a system of reels to provide and retrieve a generally continuous supply of film over the cavity. The cavity may form a portion of a sample path through which the sample is moveable. If the sample path is pressurized, the film maintains the pressure during analysis of the sample by the analysis engine.

    Abstract: An x-ray source provides both a line focus output and a point focus output, and is mounted on a rotatable support to allow easy changing between the two. A housing has ports at different angular positions relative to an anode, and each port has an associated optic appropriate for an x-ray beam passing through that port. Three or four ports may also be used to allow for different types of beam conditioning. The different beam optics may also do conditioning based on wavelength, and the anode may be of a composite material to provide different wavelength ranges. The rotatable support may be manual or motorized, and a lockout mechanism may be used to ensure that only one port is active at a time. The support may also be located on a movable table that is movable in multiple perpendicular directions.

    Abstract: An x-ray emitting window is formed at a front end face, and a taper surface tilted with respect to the x-ray emitting direction is formed near the emitting window, whereby an object to be inspected can be prevented from abutting against the front end face even if the object is pivoted about an axis intersecting the emitting direction while the object is disposed closer to the x-ray emitting window. As a consequence, while the object is disposed closer to the x-ray emitting position, the orientation of the object can be changed. Therefore, when inspecting the internal structure of the object and the like by irradiating the object with x-rays and detecting the x-rays transmitted through the object, not only a magnified penetration image of the object with a high magnification rate is obtained, but also the internal structure of the object and the like can be verified in detail by changing the orientation of the object.

A network interface communicates with the axis controller for receiving at least a portion of the program over a network.

  • Patent number: 6644853
    Abstract: A dental x-ray tube head having a housing with an x-ray tube mounted in it, with improved shielding for preventing stray radiation from emanating outside of the path of the primary x-ray beam. The shielding includes an inner hollow element encasing the x-ray tube and having an aperture through which the primary beam projects, with an open end for connecting wires to the x-ray tube. The shielding further includes an outer hollow element which fits over the inner element in such a way as to cover the open end, with clearance for the wires connected to the tube. Both the inner element and the outer element are comprised of a mixture of polypropylene and barium sulfate. The combination of the inner element and the outer element completely surrounds the x-ray tube with the barium sulfate impregnated material, eliminating the use of lead within the tube head, and thereby providing excellent electrical insulation characteristics besides the x-ray attenuation.

    Abstract: A medical examination installation has an MR system and an X-ray system that has an X-ray radiator with an X-ray tube and a solid-state X-ray image detector for producing X-ray exposures. The X-ray system has sensors for the acquisition of the location dependency of the stray field of the MR system in the three spatial axes, and coils for compensation of the stray field, and a computer that uses the output signal of the sensors to calculate a current for the coils which cause the stray field to be reduced in the region of the electron beams of the X-ray tube.

  • Patent number: 6485176
    Abstract: Inspection systems with rho-theata x-ray source motion for inspection of populated printed circuit boards and the like. The inspection systems include a transport system for transporting articles to be inspected into and out of the inspection system. An x-ray source is mounted on a first radial translation system adjacent one side of the article to be inspected for translation along an axis parallel to the article to be inspected. The first translation system is rotatably mounted about an axis perpendicular to the article to be inspected so that the x-ray source may be positioned and moved anywhere within an area by proper coordination of the angle of rotation of the rotary transport system and the translational position of the first translational system. The exemplary embodiment disclosed also includes a second translational system supported on the first translational system for movement of the x-ray source in a direction parallel to the axis of rotation of the rotary transport system.

  • Patent number: 6422747
    Abstract: In a movable type X-ray photographing apparatus, when a lever handle is operated, a force F for pushing the lever handle is inputted into a CPU from right and left pressure sensors provided in the handle. The CPU receives signals of rotational numbers V of motors from right and left encoders, and calculates a pulse width W=&agr;×f (V)×F. In accordance with the calculated pulse width W, a PWM control circuit carries out an ON-OFF duty control of a switching element in a bridge circuit of a motor driving circuit. An output torque T of the motor driving circuit is subjected to a PWM control so as to maintain a relationship (T=&agr;×f). Accordingly, the torque T truly proportional to the pushing force F is outputted from the motor, and a natural operation can be achieved.
