Definitions

  • the invention relates to a device and a method for non-destructive testing of cylindrical or tubular test objects by means of X-radiation by tomosynthesis, laminography or computed tomography.
  • Various methods are known for carrying out a non-destructive, volumetric testing of test pieces by means of X-radiation. These include, for example, tomosynthesis (TS), digital laminography (DL) or computed tomography (CT). These methods are familiar to the person skilled in the art, so that they need not be discussed in more detail here as to how these are carried out and what physical fundamentals they are based on.
  • TS tomosynthesis
  • DL digital laminography
  • CT computed tomography
  • This object is achieved by a device having the features of claim 1 when performing a tomosynthesis or laminography method and by a device having the features of claim 7 when performing a CT method and by a method - no matter which of the three It is irrelevant whether the imaging takes place by means of a surface detector, or whether a scanning line detector is used.
  • a device according to the invention achieves the object in that in a tomosynthesis or laminography method an overall device is made available which, with limited accessibility, makes the said methods feasible with good results.
  • the invention can also be used with freely accessible or non-stationary test objects.
  • essentially four assemblies are combined with one another, which in their interaction lead to the abovementioned result.
  • the bearing device is brought to the point to be examined along the longitudinal direction of the tubular strigos.
  • a voluminous image of the irradiated imaging range is calculated iteratively or by backprojection from the raw data. Due to the above-described relative movement of the radiation source to the detector and the previous positioning of the C-arm and the bearing device, a test area located inside the test object can be examined around a freely selectable fixed point.
  • the C-arm is rotatable about a rotation axis parallel to the Y-axis. This makes it possible to rotate the C-arm with its components disposed thereon X-ray tube and detector around the longitudinal axis of the test object and then to specify that shadowed structures can be imaged in other radiographic directions. If, for example, there is shading of one or more points in the vertical direction, the cone of rays can be aligned by rotation through a suitable angle so that the shading is "bypassed" because it no longer lies in the cone of rays now from another direction comes.
  • a further advantageous embodiment of the invention provides that the x-ray tube is rotatable about a tilt axis which is parallel to the x-axis and passes through the focus of the x-ray tube. In this way, even with large relative displacements between the X-ray tube and the detector, it is ensured that the detector is struck even if the angle of the beam cone is not too large. That's it not necessary to use X-ray tubes with very wide cone of rays, which generally have unfavorable imaging properties.
  • a further advantageous embodiment of the invention provides that there are two C-arms which are aligned in the Y-direction and spaced from one another and which are arranged in the region of the X-ray tube via an upper support on which the X-ray tube is mounted and in the region of the detector lower support to which the detector is mounted, are interconnected. This ensures that a very accurate guidance of both the detector and the X-ray tube on the C-arm can be done. This also applies to long relative movements of the two components of the imaging system to each other.
  • each of the C-arms is connected to the bearing device via its own slide and a respective guide device associated therewith. This ensures a stable, because at both ends of the device attacking leadership of the two C-arms, so that mechanically no deformations can occur, which could lead to an impairment of data acquisition and subsequent reconstruction.
  • a further advantageous embodiment of the invention provides that instead of the combination of C-arms and straps a dimensionally stable half-shell is present. This then fulfills the tasks of the mentioned combination.
  • This half-shell can perform a radiation protection function, especially if the connection area to the object is sealed with flexible lead matting.
  • the object is also achieved in a CT method by a device having the features of claim 7.
  • a relative movement between the x-ray tube and the Neither required nor desired. Rather, the raw data for the recording of the test object by a rotation of the C-arm about an axis of rotation, which is preferably, but not necessarily, approximately parallel to the longitudinal direction of the test object won. Due to the further structural design of the device is a precise rotational movement, which is necessary for the CT recording guaranteed.
  • the bearing device is movable perpendicular to the X-axis. This means that it can be moved in a cylindrical test object along its longitudinal axis. In this way, any desired disk that corresponds to a cross section of the test object can be approached with the bearing device and any disk of this disk can then be examined from this disk on the basis of the further device features described above.
  • the radiation source and the detector can be moved and positioned independently of each other, therefore synchronously with each other, it is possible to approach arbitrary positions within the test area along a cylindrical test object and there, due to the further device features described above, any desired To investigate the point of this disc, without implementing the system as a whole.
  • a further advantageous development of the invention provides that the bearing device is on rails that run parallel to a tube to be examined, or by means of a rail or a similar device, active or passive, is performed.
  • a forced movement of the bearing device can be specified, which always takes place along the tubular scholar mechanics, even if this should not be cylindrical but bent.
  • the Rails run within a plane that is parallel to the XY plane.
  • the XY plane is defined by the plane in which the ring is located.
  • the object is achieved by a method having the features of patent claim 12.
  • the method is carried out as follows: First, a positioning of the bearing device at the point to be examined the strig mechanics, ie the disc of the cross section of the test object, made and the bearing device to the desired Place roughly aligned and fixed locally. As a result, an unwanted overall movement of the test device is prevented.
  • the positioning can be done in different ways, for example manually, by placing the device at the point in question, or by means of a motor, which can also be remotely controllable.
  • the slide is extended along the selected slice of the test object, ie substantially perpendicular to the longitudinal axis of the test object, and the C-arm is positioned such that the point to be examined is detected by the cone of rays. In this position, the carriage is then fixed locally.

After the raw data has been recorded, it can be evaluated interactively or provided for the reconstruction of the test volume at the desired location by means of a suitable software.
  • An advantageous development of the invention provides that the x-ray tube is rotated during the recording about the tilt axis, so that it always fully illuminates the detector. As already described above for the device, this is achieved by the fact that an X-ray tube with a narrower cone of rays can be used and nevertheless always optimally raw data for each fluoroscopy direction.
  • a further advantageous embodiment of the invention provides that in a tomosynthesis or lami- nography after the local fixation of the carriage, a rotation of the C-arm about a rotation axis parallel to the Y axis takes place until a suitable angular position is reached.

  • This offers the possibility of examining a plurality of positions along the test object one after the other, wherein the new positioning can be achieved by various methods: for example by manual movement of the device or - which is advantageous - by means of a motor, the bearing device emotional. Above, it has also been suggested that this can be done along rails, so that a positive guidance with optimal alignment of the bearing device is guaranteed to strig Meeting.
