Abstract

The method involves superimposing an X-ray image acquisition of an object (10) i.e. patient, with an optical image acquisition of the object. The superimposing of the X-ray and optical image acquisitions is displayed on an output unit (5) e.g. LCD screen. Different colors and/or gray levels of the optical image acquisition are displayed with an opacity that depends on colors and/or gray levels, where the opacity includes hiding power of color shade and/or gray shade. A maximal hiding power is selected such that the X-ray image acquisition is viewable by the optical image acquisition. Independent claims are also included for the following: (1) a computer program product having instructions for performing a method for operating an X-ray device (2) an X-ray device comprising a color control module.

Description

  • The The invention relates to a specified in claim 1 method for operating an X-ray device, one in the claim 6 specified X-ray device and in the claim 9 indicated use of an object in the X-ray device.
  • at imaging devices and methods in medical technology it helpful, in addition, for example, to an x-ray image an object of investigation a corresponding, corresponding to produce an optical image. Both images are superimposed to form an image that is recognizable as revealed by x-rays Features of the examination object on the in an optical image represented surface features of the examination object and in which relationship surgical instruments, which are visible in the optical image to those revealed Characteristics of the examination object stand.
  • In the patent US 6,229,873 B1 It is described how recorded X-ray images from the interior of an examination object are superimposed with video images of the surface of the same examination subject. X-ray and video images are overlaid with identical transparency values for all pixels. Therefore, the X-ray image may be obscured by contents of the video image that are of little interest, such as skin, cloths, etc. The image quality of the X-ray image can thereby be worsened.
  • It The object of the invention is to overcome this disadvantage and a method of operating an X-ray device and to provide an X-ray device which overlaid Images displayed or displayed improved.
  • According to the Invention achieves the stated object with the method of independent Patent claim 1, the X-ray device of the independent Claim 6 and the object for use in the X-ray device of independent claim 9 solved.
  • According to the invention the method for operating an x-ray device is an overlay an X-ray image of at least one object, for example a patient, with an optical image of the object and a representation of the superimposition of the two recordings, wherein the opacity of colors and / or gray levels of the optical Image recording depending on the colors or grayscale This allows parts of the object and / or different objects according to their meaning for for example, a report or a surgical procedure more or less transparent.
  • In In another embodiment, the superimposed Images are displayed on an output unit. This offers the advantage of a simple representation.
  • In a further development, the opacity of the hue of Colors or the opacity of the grayscale of grayscale controlled become. This has the advantage of a simple color or grayscale control the opacity.
  • In In another embodiment, maximum opacity be chosen such that the X-ray image is visible through the optical image pickup. This will be ensures a good visibility of the X-ray image.
  • Of Another is a computer program product with a computer program specified which software means for performing a inventive method, when the Computer program is executed in a control unit.
  • The The invention also provides an x-ray device for illustration a superimposition of an X-ray image at least an object with an optical image of the object. The Device comprises a color control module, through which the opacity of colors and / or grayscale depending on the colors or the gray scale is controllable.
  • In a further development, the opacity of the hue of Colors or the opacity of gray scale of grayscale controllable be.
  • In In another embodiment, the illustration can an output unit, such as an LCD screen or a Video monitor done.
  • According to the invention also an object for use in an inventive X-ray device specified. The object, for example a surgical instrument, has such a color that at the image overlay a low opacity or a high opacity is generated. This can be instruments and objects, for example for a surgeon, be made visible.
  • Further Particulars and advantages of the invention will become apparent from the following Explanations of an embodiment based of schematic drawings.
  • It demonstrate:
  • 1 an X-ray device according to the invention and
  • 2 a flowchart of a method according to the invention.
  • 1 shows a block diagram of an X-ray device according to the invention. An X-ray unit 1 . 2 with an X-ray source 1 and with a digital x-ray detector 2 , as well as a video camera 3 are with an overlay unit 4 connected. The overlay unit 4 itself is in turn like an image output unit 5 , For example, a video monitor, connected. In the image recording field of the X-ray imaging unit 1 . 2 and the video camera 3 are an object to be examined 10 with a surface 11 as well as surgical instruments 12 , With one the object 10 penetrating x-ray beam 6 the X-ray unit 1 . 2 a plurality of projection data sets, so-called single images, is generated, from which a three-dimensional first image data record from the interior of the object 10 is reconstructed. With the help of the video camera 3 becomes a two-dimensional second image data set of the surface 11 of the object 10 and the instruments 12 according to the orientation and zoom setting of the video camera 3 generated. From the three-dimensional first image data set, a projection image in the recording geometry of the video camera is produced by means of digital projection 3 generated. It is congruent with the second image data set in the overlay unit 4 overlaid and on the output unit 5 visualized. This creates a congruent, directionally accurate summation image of the outer and inner structure of the object 10 and used surgical instruments 12 ,
  • With the overlay unit 4 is a color control module 7 electrically connected. The color control module 7 Controls the color representation of the video image on the output device 5 , The opacity OZ is controlled by colors and grayscale depending on the color or the gray level. That is, for example, blue-colored instruments 12 with a high hue coverage power and white or green cloths as well as red skin and blood with low opacity or high transparency. This will be the important tools 12 In contrast, the unimportant structures visually recede into the background and do not cover the X-ray images.
  • The Opacity or contrast is a measure of the ability of one color to cover another color. The lower the opacity, the less one color can change Cover the color.
  • In the color control module 7 Shades of hue to opacity, maximum hiding limits, and anti-aliasing and transparency mask noise filters are stored.
  • The Device is for both color and for Monochrome overlays can be used.
  • In 2 the flowchart of a method for operating an X-ray device according to the invention is shown. The procedure is first in step 100 an object 10 selected and between X-ray source 1 and x-ray detector 2 placed. In the steps 101 and 102 An X-ray image RA and an optical image acquisition OA are generated. Both shots RA, OA are in step 103 superimposed and taking into account a specifiable color or grayscale opacity OZ on an output unit 5 shown. The opacity OZ or transparency of the colors or gray levels occurs as a function of the color or the gray levels.
