  • Patent number: 8023615
    Abstract: In a medical X-ray CT apparatus, a rotary portion is rotated, and a wind is produced inside the apparatus by the rotation of the rotary portion. An expanded cover portion is forced to vibrate by the wind, and noise is produced. The expanded cover portion is provided with at least one curved member including both ends. The curved member is arranged to extend along a virtual projection line obtained by geometrically projecting a virtual straight line connecting, to each other, the two ends fixed to an outer peripheral edge of an opening of the expanded cover portion onto a surface of the expanded cover portion, and the vibration of the expanded cover portion is reduced.

    Abstract: A dental product for the evaluation, according to scale, of X-ray recordings of areas which are to be diagnosed, in particular areas of the tooth and/or jawbone, within the oral cavity of a patient, has a main body 10?, the shape of which is such that it is able to be received by the patient and is able to be fixed in the immediate vicinity of the area which is to be diagnosed by X-raying. The main body 10? consists of a material which is penetrable by X-ray beams, wherein in the interior of the main body at least one reference object 12? is held, which consists of material which absorbs X-ray beams. For the diagnosis, the dental product is placed into the patient's mouth and is fixed in that the patient bits onto the dental product.

  • Patent number: 7934869
    Abstract: Embodiment of the invention describes a system and a method for positioning an object from a first pose to a second pose. The method displays concurrently a first image and a second image on a display device, wherein the first image and the second image represent respectively the first pose and the second pose of the object. The method updates, in response to a change in a pose of the display device, the second image such that an alignment of the first image and the second image on the display device depends on the change in the pose of the display device, and positions the object from the first pose to the second pose based on the change in the pose of the display device.

  • Patent number: 7916829
    Abstract: The invention relates to a computed tomography method. The airgap associated with a projection direction is determined by determining, in the projection images, edge pixels which map object edges on a detector. By back-projecting the edge pixels in an object image space it is possible to determine an envelope polygon for an outline contour of the examination object. The width of the airgap associated with a specific projection direction can then be determined on the basis of the envelope polygon. Exact knowledge of the current airgap serves to improve the scattered radiation correction.

  • Patent number: 7887237
    Abstract: A computed tomography apparatus has a gantry for mounting components of an acquisition system that are arranged such that they can rotate around a system axis, and a stationary part in which the gantry is supported such that it can tilt. A device for cooling the components by airflow is arranged on the gantry. The cooling device has at least one feed channel and at least one air discharge channel that are arranged between the stationary part and the gantry so that the air current introduced into the gantry via the stationary part is conducted out from the gantry into the stationary part in a directed manner after cooling the components. The direction of the air current directed from the computed tomography apparatus thus does not depend on the tilt of the gantry. Moreover, the computed tomography apparatus is designed such that cooling is achieved with low noise emission since the direct sound propagation path between the exit opening and the gantry is interrupted.

  • Publication number: 20090074149
    Abstract: The invention relates to a medical diagnostic apparatus (1) and to a hose (21) suitable for guiding connections in a medical diagnostic apparatus. The medical diagnostic apparatus (1) comprises a frame (5), a rotatable support (3), at least one connection extending between the frame and the rotatable support, and a hose (21) for guiding this connection. The hose (21) is provided with a chain (29) of reinforcement elements (31). The chain (29) extends mainly in the longitudinal direction of the hose (21). In the chain (29) the reinforcement elements (31) are connected to each other. These reinforcement elements (31) can also be rotated with respect to each other about an axis which is perpendicular to the longitudinal axis of the hose (21), while they are substantially rigidly connected in a direction along their rotation axis.

  • Patent number: 7503694
    Abstract: A device and method for evaluating the performance of X-ray machines used to produce radiographic images is described. An analyzer including an X-ray dosimeter and an imaging device is sent to the facility having the X-ray machine to be evaluated. The analyzer may be used with a film pack or a digital image detector. The analyzer is exposed in accordance with testing instructions and returned to an evaluation agency. The radiation dose and HVL is determined from the dosimeter, and the image quality is determined from analysis of a radiograph of a target having differing X-ray absorption portions. A data base of results may be used to provide comparative analysis.

  • Publication number: 20090046463
    Abstract: Systems, methods and apparatus for illuminating a mobile imaging system by use of a light source operable to emit light for status indication, pathway illumination, and/or creation of favorable lighting environment. A triggering signal originating from a photosensor arranged to receive light at the mobile imaging system, a signal indicative of movement of the mobile imaging system, or user or system command is used to adjust the lighting source. The light source can be a light emitting diode (LED), collimator lamp, halogen lamp, fluorescent lamp, organic display, or any other light-emitting technology. The light source is adjustable as to color and intensity and can indicate the mobile imaging system's condition, status, or event.

  • Patent number: 7492866
    Abstract: The present invention relates to a collision detecting device for a radiation treatment apparatus, comprising a radiation unit having an internal space, for directing radiation beams towards a radiological focus in the internal space for treatment of a target in a patient's body therein. The collision detecting device comprises a collision detecting unit being electrically conductive at least on its outer surface and having a size slightly smaller than the internal space of the radiation unit, so as to be insertable into the internal space and held in an electrically insulating manner in respect of the radiation unit by spacer elements. The outer electrically conductive surface is connectible to an electrical voltage supply in order to detect if the outer surface of the collision detecting unit abuts against the inside surface of the radiation unit. The invention also relates to a method for performing such collision detection.

  • Patent number: 7478948
    Abstract: A rotary mechanism uses a rolling element, an outer-ring housing member and an inner-ring housing member. The outer-ring housing member or the inner-ring housing member is divided thicknesswise into two parts, to have a gap at between the two-divided parts of the housing member. Due to this, slide resistance can be caused by deforming the rolling element received in the outer-ring and inner-ring housing members.

  • Patent number: 7465089
    Abstract: A disposable plastic covering includes a seal region and an apron region for use in directing fluids away from an interior region of the machine to prevent the fluids from entering a CT machine. The covering includes an inert adhesive material for securing a seal. The adhesive material fastens the seal region of the plastic covering across an opening between an external casing and a window arranged above a moving ring upon which an X-ray emitter and detector are arranged. The apron region of the plastic covering extends from within a central opening of the CT machine to direct fluids from within the machine to an exterior of the machine. A second plastic covering is arranged on an opposite side of the window and seals the second seam. A further embodiment includes a pouch region in the disposable plastic covering for directing fluid therein. An additional covering is provided for controls of the machine.
