Abstract

The present invention relates to a mobile X-ray device, comprising: a housing with an X-ray source arranged therein, a sensor system comprising one or more sensors for aligning the X-ray source to an object to be scanned and/or detecting at least one extrinsic object in a predefined area in a vicinity of the X-ray beam of the X-ray source; a processor unit comprising determining the alignment of the X-ray source and the object to be scanned based on signals received from the sensor system; image acquisition for generating an X-ray image; activating a blockage signal for the mobile X-ray device based on signals received from the sensor system; and an interface for outputting the generated X-ray image and/or information; wherein image acquisition is blocked, if the sensor system signals one of the following: at least one extrinsic object is detected within the predefined area; lack of alignment between the X-ray source and the object to be scanned.

First claim

The invention claimed is:

1. A mobile X-ray device comprising:
a housing with an X-ray source;
a sensor system comprising at least one sensor for aligning the X-ray source with an object to be scanned and detecting at least one extrinsic object in a predefined area near an X-ray beam of the X-ray source;
a processor configured to
determine whether the X-ray source and the object to be scanned are aligned based on signals received from the sensor system;
perform an image acquisition for generating an X-ray image; and
activate a blockage signal based on the signals received from the sensor system; and

an interface for outputting the generated X-ray image;
wherein the image acquisition is not performed when the signals indicate that:
the at least one extrinsic object is detected within the predefined area; or
the X-ray source and the object to be scanned are not aligned.

2. A mobile X-ray system, comprising:
an X-ray detector; and
a mobile X-ray device that includes:
a housing with an X-ray source;
a sensor system comprising at least one sensor for aligning the X-ray source with an object to be scanned and detecting at least one extrinsic object in a predefined area near an X-ray beam of the X-ray source;
a processor configured to
determine whether the X-ray source and the object to be scanned are aligned based on signals received from the sensor system;
perform an image acquisition for generating an X-ray image; and
activate a blockage signal based on the signals received from the sensor system; and

an interface for outputting the generated X-ray image;
wherein the image acquisition is not performed when:
the at least one extrinsic object is detected within the predefined area;
the X-ray source and the object to be scanned are not aligned; or
the X-ray source, the X-ray detector and the object to be scanned are not aligned.

3. The system according to claim 2 , wherein an operator and/or the object to be scanned is identified.

4. The system according to claim 3 , wherein the blockage signal is cancelled when the operator is identified as an expert.

5. A method for image processing by a mobile X-ray system that comprises an X-ray source, a sensor system and an X-ray detector, the method comprising:
determining, by the sensor system, whether the X-ray source, an object to be scanned and the X-ray detector are aligned;
detecting, by the sensor system, at least one extrinsic object in a predefined area near an X-ray beam of the X-ray source;
performing an image acquisition for generating an X-ray image;
outputting the generated X-ray image; and
blocking the image acquisition when
the at least one extrinsic object is detected within the predefined area; or
the X-ray source, the object to be scanned and the X-ray detector are not aligned.

6. The method according to claim 5 , wherein the predefined area is an area extending from the X-ray source and comprises a vicinity of the X-ray beam, the object to be scanned and the X-ray detector.

7. The method to claim 5 , wherein the predefined area comprises:
a core area including the X-ray beam, the object to be scanned and the X-ray detector, wherein the core area extends a first predetermined distance;
a secondary area extending from the core to a second predetermined distance; or
a secure area extending from the secondary area and including the vicinity of a mobile X-ray device.

8. The method according to claim 7 , wherein the predefined area comprises the core area, the secondary area and the secure area when an operator is identified as low-skilled.

9. The method according to claim 7 , wherein the image acquisition is continued when the extrinsic object is detected in the core area or the secondary area, and an operator is identified as an expert operator.

10. The method according to claim 7 , wherein the core area, the secondary area or the secure area is defined by comparing a pre-calculated X-ray radiation dose against an actual X-ray radiation dose at a position of the detected extrinsic object.

11. The method according to claim 10 , further comprising performing a calibration by the mobile X-ray system to adjust the pre-calculated X-ray radiation dose in a database according to usage requirements of the mobile X-ray system.

12. The method according to claim 5 , further comprising outputting information based on data received by the X-ray detector, the information comprising a possible treatment or a diagnosis.

13. The method according to claim 5 , further comprising tracking the at least one extrinsic object.

14. A non-transitory computer-readable medium having one or more executable instructions, when executed by a processor, cause the processor to perform a method for image processing by a mobile X-ray system that comprises an X-ray source, a sensor system and an X-ray detector, the method comprising:
determining, by the sensor system, whether the X-ray source, an object to be scanned and the X-ray detector are aligned;
detecting, by the sensor system, at least one extrinsic object in a predefined area near an X-ray beam of the X-ray source;
performing an image acquisition for generating an X-ray image;
outputting the generated X-ray image; and
blocking the image acquisition when
the at least one extrinsic object is detected within the predefined area; or
the X-ray source, the object to be scanned and the X-ray detector are not aligned.
