The invention provides a method for the graphical representation of a medical instrument inserted at least partially into an object under examination, with an image representing the medical instrument being generated, in that the instrument image is vectorized, with the medical instrument being represented as a polyline.

An automobile or vehicle having a high efficiency solar control system is provided. The automobile may have a painted surface and a film mounted to its exterior side. The film may reflect solar radiation in the near and mid infrared ranges yet allow high transmission of light in the visible range such that the painted panel may be seen. The film may have a layer of silver which reflects the solar radiation in the near and mid infrared ranges. Since the silver is susceptible to oxidation and turns the silver into a black body which absorbs the near and mid infrared radiation, the film may be designed to slow the rate of oxidation of the silver layer to an acceptable level. The silver layer may be sandwiched between the glass which does not allow oxygen to diffuse there through and reach the layer of silver and a stack of sacrificial layers having a certain thickness which slows down the rate of oxygen diffusion to an acceptable level.

A method is provided for recording an examination object using an x-ray recording system having an x-ray source and an x-ray detector rotatable about a common axis of rotation. X-ray detector is displaced in a first direction enclosing a first angle k between a perpendicular bisector from x-ray source to x-ray detector and a plane running through x-ray source and containing the axis, k≠0. First x-ray images are recorded in angular positions of x-ray source and x-ray detector displaced in the first direction in a first rotation. X-ray detector is displaced in a second direction enclosing a second angle m between the bisector and the plane, m≠0 and is on an opposite side from k. Starting points of the rotations are differed by an angle of displacementβ0=k+m+d2,where d is the detector fan angle. Starting points and finishing points of the rotations are spanned by π+β0.

The present invention relates to a method for assisting with percutaneous interventions, wherein 2D x-ray images of an object region are recorded before the intervention using a C-arm x-ray system or a robot-based x-ray system at different projection angles and 3D x-ray image data of the object region is reconstructed from the 2D x-ray recordings. One or more 2D or 3D ultrasound images are recorded before and / or during the intervention using an external ultrasound system and registered with the 3D image data. The 2D or 3D ultrasound images are then overlaid with the 3D image data record or a target region segmented therefrom or displayed next to one another in the same perspective. The method allows a puncture or biopsy to be monitored with a low level of radiation.

There is described a radiography device for recording dynamic processes and an associated recording method. The radiography arrangement is used to examine patients using an x-ray source, a digital flat detector with a single shot recording function and an operating console for controlling and recording purposes, with the flat detector also being able to display an image sequence at a rate of up to 5 Hertz, which allows the positioning of the region to be examined or the monitoring of pseudo-interventional interventions.

A scanner for scanning a body part of a human, such as, for example, a breast of a woman includes a supporting part for the upper body of a human, a receiving space for the body part to be scanned, possibly a compression device for pressing against the body part introduced into the receiving space, and a camera which is arranged to form an image of the body part introduced into the receiving space and pressed against by the compression device, with the aid of high-energy radiation emitted by the body part. The camera includes a collimator having a movable collimator part which has an incident surface facing towards the receiving space. The collimator defines and delimits an astigmatic, two-dimensional collection of radiation channels for the high-energy radiation.

The invention belongs to the field of energy conservation of buildings, and particularly relates to an energy-saving window with a vacuum layer combined with a convection layer and an installation and use method of the energy-saving window. The energy-saving window comprises vacuum interlayer outside glass, middle glass, convection interlayer outside glass, a vacuum interlayer and the ventilating convection layer. A vacuum interlayer upper ventilating pore groove and a vacuum interlayer upper ventilating pore groove opening and closing plate are arranged between an upper window frame and the upper portion of the vacuum interlayer; a convection interlayer upper ventilating pore groove and a convection interlayer upper ventilating pore groove opening and closing plate are arranged between the upper window frame and the upper portion of the convection interlayer outside glass; and a convection interlayer lower ventilating pore groove and a convection interlayer lower ventilating pore groove opening and closing plate are arranged between a lower window frame and the lower portion of the convection interlayer outside glass. Indoor all-year reasonable radiation, convection and vacuum heat insulation effects are realized by means of opening or closing the different ventilating pore grooves, so that the requirement of energy conservation of buildings is met.
