Method, apparatus and X-ray recording system for visualization of an X-ray region
A visualization of an X-ray region during the production of an X-ray recording of an object is produced. In order to reduce radiation exposure for a physician and/or the patient during X-ray recordings, a proposal is made to record a video image of a region, which is captured by a beam from the X-ray source, of the object, to display the video image and to represent at least a portion of the beam in the displayed video image.
1. A method for visualizing an X-ray region formed during a production of an X-ray recording, wherein the X-ray recording relates to at least one region of an object located in an object plane, the at least one region disposed between an X-ray source and an X-ray receiver and is captured by a beam from the X-ray source, which comprises the steps of:
recording a video image of the region of the object;
displaying the video image; and
representing at least a portion of the beam as an inner core region in the displayed video image and representing a rim region located outside the inner core region in the displayed video image, wherein the rim region is shown in the displayed video image in a way indicating that the rim region is exposed to lesser radiation than the inner core region.
2. The method according to claim 1 , wherein a virtual recording region of the X-ray recording is represented as the portion of the beam.
3. The method according to claim 2 , wherein the virtual recording region corresponds to an intersecting area between the beam and the object plane.
4. The method according to claim 2 , wherein the virtual recording region is represented even before the X-ray recording is produced.
5. The method according to claim 2 , wherein the virtual recording region is represented in color.
6. An apparatus for visualizing an X-ray region for use in an X-ray recording system, the X-ray recording system having an X-ray source and an X-ray receiver for producing an X-ray recording of at least one region of an object disposed in an object plane, the at least one region disposed between the source, the apparatus comprising:
a video camera for recording a video image of the region of the object;
a screen for displaying the video image;
a device for representing at least a portion of the beam as an inner core region in the displayed video image; and
a data processing unit configured for causing said device to display a rim region located outside the inner core region in the displayed video image, wherein the rim region is shown in the displayed video image in a way indicating that the rim region is exposed to lesser radiation than the inner core region.
7. The apparatus according to claim 6 , further comprising a device for ascertaining a distance from the object to the X-ray receiver.
8. An X-ray recording system, comprising:
an X-ray source;
an X-ray receiver for producing an X-ray recording of at least one region of an object located in an object plane, the at least one region disposed between said X-ray source and said X-ray receiver and is captured by a beam from said X-ray source;
an apparatus for visualizing an X-ray region for use in the X-ray recording system, said apparatus containing:
a video camera for recording a video image of the at least one region of the object;
a screen for displaying the video image;
a device for representing at least a portion of the beam as an inner core region in the displayed video image; and
a data processing unit configured for causing said device to display a rim region located outside the inner core region in the displayed video image, wherein the rim region is shown in the displayed video image in a way indicating that the rim region is exposed to lesser radiation than the inner core region.
9. A non-transitory computer readable medium including a computer program stored thereon for visualizing an X-ray region formed during a production of an X-ray recording, wherein the X-ray recording relates to at least one region of an object disposed in an object plane, the region is disposed between an X-ray source and an X-ray receiver and being captured by a beam from the X-ray source, the computer program having computer executable instruction to be executed in a computer and programmed to:
calculate at least a portion of the beam; and
represent at least one portion of the beam as an inner core region in a displayed video image of the region of the object and represent a rim region located outside the inner core region in the displayed video image, wherein the rim region is shown in the displayed video image in a way indicating that the rim region is exposed to lesser radiation than the inner core region.
