Definitions
- the invention relates to a camera that is sensitive to X-rays and that includes an image receiver that is sensitive to X-rays to create a first layer image with a first depth-of-field profile and to an X-ray device with such a camera.
- Such a camera is used to create dental panoramic slices using an X-ray device.
- the depth of field is determined by the resolution that has just been accepted in the x-ray image to be taken, the transition from a range of maximum resolution to a representation that is no longer recognizable being fluid.
- This principle of blurring is known and is based essentially on the speed of the X-ray fan on the one hand and the film speed or its digital equivalent on the other.
- PRIOR ART EP 0 229 971 discloses a dental X-ray diagnostic device for taking panoramic slice images of a patient's jaw.
- panoramic slices PAN shots
- one or more sections of the jaw can be selected in multiple layers alongside one another on the film (multi-slice shots).
- a film cassette holder is fastened to a rotary unit carrying the X-ray source in such a way that it can be pivoted from a position of use into a non-use position, with which the generation of cephalometric images (Ceph images) is made possible because the X-ray Radiation source shines undisturbed past the film cassette holder.
- EP 0 632 994 A1 discloses an X-ray diagnostic device for taking X-rays of body parts of a patient, in which a line detector camera with an X-ray detector is provided, the width of which is adapted to the width or length of the body part to be recorded.
- the line detector camera can be moved together with the radiation source along the body part to be recorded via adjusting means.
- the X-ray diagnostic device can be designed both for the creation of a PAN image and for the creation of a remote image (Ceph), the line detector camera for the creation of the respective image being repositionable and for this purpose having a connection part which has connection means for a detachable mechanical and include electrical connection with a holder.
- various options for guiding the X-ray fan when creating the remote image with a moving radiator or a primary diaphragm or both together are disclosed.
- a reversible camera is described in detail in EP 0 634 671 AI, with particular reference being made to the releasable attachment of the camera to a holder.
- EP 0 858 773 A2 discloses a detector arrangement for taking X-rays, which consists of detectors in the dimensions of the detector of an intraoral sensor.
- the detector arrangement is designed in such a way that transversal slice recordings (TSA recordings) can be taken, the detector arrangement being held within the line detector camera so as to be adjustable in the direction of its longitudinal axis.
- TSA recordings transversal slice recordings
- the detector elements can by means of a Adjustment device can be adjusted along the main axis of the detector.
- the sensors used in EP 0 858 773 A2 to create a PAN or Ceph image typically have 135 to 180 mm in the image height and approximately 6 mm in the image width.
- the sensors used to create TSA images typically have dimensions of approximately 30 x 20 mm.
- the difference in width results from the fact that with the panoramic layer image a layer thickness (depth of field) of the sharp layer is desired at least as large as the thickness of the object being captured, whereas with TSA image the layer thickness (depth of field) of the sharp layer is approximately 1 to Is 3 mm.
- the reduced layer thickness and the reduced depth of field require, in principle, a wider image receiver when taking the pictures using a CCD sensor which is operated according to the TDI principle.
- This also applies to image receivers that provide individual images in the form of a surface image, which are subsequently computer-aided to offset the corresponding depth of field to obtain a corresponding layer image.
- image receivers are, for example, CMOS detectors.
- the camera used for the creation of the panoramic layer image can also be used for the creation of a Ceph image by repositioning, a further camera is still required for the creation of a TSA image provides the sensor dimensions required for this.
- an X-ray-sensitive camera which has a first X-ray-sensitive image receiver for creating a first layer image with a first depth of field profile. Furthermore, a second X-ray sensitive image receiver is provided for the creation of a second slice image with a second depth of field.
- This camera is therefore suitable for taking different types of layer photographs.
- the second depth of field curve is significantly smaller than the first depth of field curve.
- Such a camera is therefore suitable not only for the creation of panoramic slice photographs but also for the creation of lateral or transverse slice photographs, generally referred to as multi-slice photographs. Thanks to the invention, PAN or T ⁇ A recordings can be made with a single camera.
- the second image receiver is at least twice as large as the first image receiver in a first dimension of its active area provided for image acquisition.
- the second image receiver in a second dimension can be at most half the size of the first image receiver.
- the second image receiver is advantageously arranged laterally next to the first image receiver. As a result, the shoulder freedom of the patient from whom an X-ray is to be taken is not restricted by the camera.
- the second image receiver is advantageously arranged on the back of the first image receiver.
- a camera can be installed in conventional X-ray devices for the creation of PAN images and thus provide a retrofit for creating multi-layer images, in particular when the camera can be reversed in its orientation to the X-ray emitter, for example.
- the camera is advantageously designed such that the second image receiver can be retrofitted. In this case, it is possible to first equip an X-ray device with the camera to take PAN images and only to insert the second image receiver into the camera when necessary to take multi-layer images.
- the second image receiver is part of the first image receiver or vice versa.
- the image-receiving area provided by the second image receiver can be used even if no image typical for this receiver is created, and on the other hand, part of the first image receiver can be used to create the image with the second image receiver.
- adjustment means are provided in order to selectively convert the first image receiver or the second image receiver into one for creating the respective one X-ray to bring required alignment to an X-ray tube.
- the adjusting means and the two image receivers can be provided in a common housing of the camera or on the housing of the camera and in the area of a coupling for attaching the camera to a support, the camera as a whole then being adjustable relative to the coupling. In the latter case it is possible to visually check the position of the camera from the outside and to determine whether the correct sensor has moved into the position appropriate for the picture. Furthermore, the camera housing can be kept more compact than if the sensors are moved within the entire camera housing. If the camera has a radiation-transmissive area, it is possible to leave the camera in the X-ray fan of another picture to be taken without the image creation being significantly impaired. This allows the camera to remain in place and does not have to be removed.
- the radiation-transmissive region is arranged between the first and the second image receiver.
- the radiation-transmissive area is arranged next to the first and the second image receiver.
- an x-ray device with an image receiver provided in an x-ray sensitive camera which furthermore has an x-ray emitter with a primary diaphragm and adjustment means for the image receiver and / or the x-ray emitter and / or the Primary aperture and / or combinations thereof includes.
- a second image receiver is provided within the camera and the second image receiver can be brought into the beam path of the X-ray emitter by means of the adjusting means.
- Adjustment means cooperating with the camera are advantageously provided, the adjustment means being able to be provided in the housing of the camera or in a coupling between the camera and the carrier or on the carrier itself.
- the adjustment path of the camera is at least one width of the first sensor, so that it can be completely shifted out of the beam path of the X-ray fan for recording with the second image receiver.
- the x-ray device can additionally be provided with a device for the creation of cephalometric images with a further image receiver.
- the camera is in the alignment of the X-ray tube to create the cephalometric image in the area of
- the beam path is arranged between the X-ray emitter and the image receiver of the device for the creation of cephalometric images and is radiolucent in this area.
- the adjustment path can be dimensioned such that when the x-ray emitter is aligned to produce the cephalometric image, the camera can be guided out of the beam path between the x-ray emitter and the image receiver of the device for the creation of cephalometric images

- the image receiver 4 can be divided into an image reception area in the form of a CCD sensor 4.1 and a readout electronics 4.2.
- Such designs of an image receiver are well known in the prior art.
- image receivers that provide individual images in the form of a surface image such as CMOS sensors, can also be used.
- FIG. 1b shows a cross section through the camera 1 according to the section line from FIG. In the housing 2, the circuit board 3 is shown with the first image receiver 4 and the second image receiver 5, the second image receiver 5 being inserted into a receiving device 8 of the circuit board 3.

- 3a-d show different embodiments of an image receiver which consists of the two above existing image receivers 4, 5 is composed "virtually".
- the virtual image receiver 31 can be designed such that the required length of the line detector of the image receiver 4 is supplemented (FIGS. 3a - 3c).
- the virtual image receiver 31 can also be so be designed such that the image receiver 4, which is designed as a line detector, supplements the width of the image receiver 5, which is designed as a surface sensor (FIG. 3d).
- X-ray devices for taking panoramic slice images have a fixed coupling between the X-ray emitter on the one hand and the receiver on the other, so that both are moved together.
- the receiver is rigidly attached to the common support together with the X-ray source.
- the camera 41 fastened to a support structure 40 has a housing 42 in which the image receivers 4, 5 are shown via an adjustment mechanism in the form of a slide 43 which is guided on an adjustment track 44.
- the image receivers 4, 5 can be brought from the position shown into the dashed position 4, 5 V via the slide 43 and the adjustment mechanism 44, so that instead of the area sensor of the image receiver 5, the line detector of the image receiver 4 is shown in the beam fan of the X-ray beam through line 45.
- the adjustment mechanism is arranged between a camera 41 and the carrier 40.
- the camera 41 is displaceably connected to the support structure 40 via its housing 42, represented by the slide 43 arranged on the camera and the adjustment track 44 arranged on the support structure 40.
- the entire camera 41 can thus be moved from the position shown to the position shown by the dashed line Shift the position shown in the line so that the beam fan of the X-ray beam, again represented by the line 45, is aligned from the image receiver 5 to the image receiver 4.
- the camera 41 is attached via a coupling, and the coupling means themselves can contain adjustment means. However, this is not shown.
- a motorized camera holder can be used to create a TSA picture, whereby the sensor is adjusted depending on the specified operating mode.
- the motor-adjustable camera holder provides the connection between the coupling of the camera and the carrier. It can be designed such that the camera can be moved with a coupling on a sliding track or by means of a swivel device. In this way, the camera can be automatically moved to the optimal position on the device. This enables a direct recording sequence of a PAN recording with subsequent multi-layer recording without additional intervention by the operator.
- FIG. 5a shows essential parts of an X-ray device 50, namely a recording device with a recording unit 51 and an X-ray emitter 52, the object to be examined being arranged in the form of a patient's head in the beam path between the X-ray emitter 52 and the recording unit 51.
- the X-ray beam 54 emerging from the X-ray source 52 is aligned with the image receiver 4 designed as a line detector, so that the length required to create a panoramic slice of the upper and lower jaw arch is provided.
- the recording unit 51 and the X-ray emitter 52 are attached to a common carrier and can be moved around the object to be examined at least in part.
- the image receiver 5 in the form of the area sensor is in a rest position outside the X-ray beam 54.
- FIG. 5b shows the recording situation for the creation of a multi-layer recording of a subarea of interest of the jaw arch, for example a single tooth.
- the camera arranged on the recording unit 51 is now oriented such that the image receiver 5 is exposed by the X-ray beam 54, whereas the image receiver 4 is in a rest position.
- the image receiver 4 which is arranged facing the X-ray emitter, would accordingly be located once, while the image receiver 5 would be located other times.
- the camera can be repositioned or automatically reversed by motorized adjusting means.
- 5c shows a basic diagram for creating a ceph image.
- the creation of a Ceph image can be carried out in an X-ray device equipped with a PAN unit “A” and a Ceph unit “B” in such a way that a separate camera 61 with an image receiver 62 with a corresponding image is used for the creation of the Ceph image long sensor is placed in the ceph position.
- the camera 55 for creating the PAN and multilayer image is adjusted such that the X-ray fan 54 emerging from the X-ray source 52 passes the housing of this camera 55.
- FIG. 5d shows a recording unit 51 in which an area 56 that is transparent to X-rays is present between the two image receivers 4, 5.
- the dimension of the area 56 is dimensioned such that an X-ray fan 54 emanating from the X-ray emitter 52 penetrates through the camera essentially unaffected.
- the camera is stationary and the X-ray fan 54.1-54.3 is aligned with the respective image receiver 4, 5, 62 via an adjustable primary diaphragm 57.
- the primary dimensions of the primary diaphragm 57 are matched to the receptacle to be created in each case. For example, the width for creating a PAN image is 0.9 mm.
- the primary diaphragm 57 here has two openings which can release the X-ray fan 54.1, 54.2 corresponding to the different types of exposure.
- the other X-ray fan is of course hidden to create the picture.
- the beam cone 58 provided by the X-ray emitter is large enough to provide the desired X-ray fans 54.1, 54.2 or, if applicable, the X-ray fans for long-distance X-ray imaging.
- the X-ray emitter 52 can also be aligned with the desired image receiver 4, 5 by adjusting means, shown in FIG. 5f.
- a such adjustment is already known for PAN / Ceph combination devices. The adjustment can be done by moving or by pivoting as shown.
- the advantage here is that the central beam of the X-ray fan 58 always lies in the X-ray fan 54.
- a PAN image can be taken in a first orientation of the camera 2, the image receiver 4 being located in the X-ray fan 54.1.
- a ceph image can also be taken in this orientation of the camera 2, since the X-ray fan 54.3 radiates past the camera 2.
- a multi-layer image can be created.
- the image receiver 4 is arranged closer to the X-ray fan 54.3 of the Ceph image than the image receiver 5.
- the arrangement shown has the advantage that a short cantilever for the ceph camera is sufficient for the creation of the ceph image, since the x-ray fan 54.3 remains close to the wall.
- the primary aperture for creating a PAN image, a multi-layer image and a CEPH image is different and that an image is only created with a single type of image. If a plurality of X-ray fans are shown at the same time in the exemplary embodiments, this is only used to clarify the geometric relationships. However, the primary diaphragm is designed and is set so that the desired image receiver is acted upon by the X-ray fan provided for the image generation.
