Definitions
- Tomography devices such as known from DE 26 17 974 C2 have a Ge housing to protect the electronic components of the tomography device from contamination or external mechanical effects but also to protect people from injuries during operation of the tomography device .
- the essential components of the recording system namely the radiation source and the detector, are thus usually separated from one another by a measuring range assigned to the recording system by the housing.
- the housing typically comprises a receiving window, through which the X-ray radiation can pass unhindered.
- the recording window used is a sealing strip made, for example, of Makrolon 6870, which is arranged in a ring around the measuring area to be examined and assigned to the rotating part of the gantry, so that the X-ray radiation and a projection laser for projection of the recording plane generated laser light can pass unhindered through the sacred ⁇ window.
- the receiving window is not only permeable to X-radiation and laser light, but also to visible light.
- the receiving window can have both a tinting and a mirroring, so that in combination visibility of the interior of the device is reduced even more than when tinting and mirroring are used alone.
- the tinting or the mirroring of the receiving window can preferably be accomplished by a separate layer.
- the base material for example, Makrolon 6870 can be used.
- the at least the light in the visible Spekt ⁇ rum strongly debilitating separate layer can be glued on a simple Wei ⁇ se on the base material, thermally evaporated or sputtered.
- sputtering also called sputtering, ions are generated from a gas, for example argon, and accelerated in an electric field to a so-called target, which has the same material of the separate layer to be applied.
- FIG. 3 Transmittance of red lacquer as a function of the wavelength of light in the form of a diagram
- FIG. FIG. 4 shows the detail from FIG. 2, wherein the receiving window, however, has a mirroring in the form of a separate layer
- Patient 21 shown in a perspective view.
- a scattering tolerance of 1 mm for passing through the sacred ⁇ window laser light is not exceeded;
- the material used for the recording window or the spectral properties of the receiving window are ge compared to X-radiation resistant;
- the additional background noise of the detector and the visibility of components in the interior of the computed tomography device are reduced by the fact that the receiving window has a selective light-filtering property.
- FIG. 2 shows a detail of a section of the housing 6 with the receiving window 1 having a tint 8 in an axial longitudinal section along section line II in FIG.
- the tint 8 of the receiving window 1 considerably attenuates the incident visible light in the direction of entry 27 and the remaining light components reflected in the interior of the housing 6 in the exit direction 26 by the components 16, 17, 18, so that a measuring range 24 tioned patient 21 does not gain insight into the interior of the device.
- the tone should at the same time be selected such that a transmittance of less than 70%, preferably less than 30, is present in the remaining wavelength range of the visible light %, er ⁇ aims.
- Tints with such a spectral property are present, for example, in the red lacquer of the KASI 350 type and in the yellow lacquer of the KASI 250 type.
- polycarbonate (Makrolon 6870) or Plexiglas is suitable as the base material 11 for producing the receiving window 1, in which the tint 8 is introduced.
- FIG. 3 shows the spectral characteristic 14 by way of example for the red lacquer of the type KASI 350, which can also be used, for example, for painting the embodiment of a fourth pickup window 4 shown in FIG. 5, in the form of a diagram, the degree of transmission 28 depending on the Wavelength 29 of the light is plotted. Accordingly, the visible light is largely weakened in a region of the wavelength between 400 nm and 600 nm, so that only a very small proportion of the incident light reaches the interior of the device and can be reflected back by the components arranged there.
- the transmittance is less than 50% in this range, and even less than 25% in a wavelength range between 400 nm and 550 nm. For this reason, a patient positioned in the measuring range will not be able to perceive the rotating recording system during the examination.
- the selective light filter characteristic of the capture window can also be accomplished with an optical bandpass filter.
