Abstract

An X-ray emission device for emitting an integrated X-ray beam toward an object is disclosed. The X-ray emission device includes multiple X-ray emission tubes for respectively generating multiple X-rays, and a lens module for guiding the multiple X-rays toward the object to form the integrated X-ray beam.

First claim

What is claimed is:

1 . An X-ray emission device for emitting an integrated X-ray beam toward an object, the X-ray emission device comprising:
a plurality of X-ray emission tubes for respectively generating a plurality of X-rays; and a lens module for guiding the plurality of X-rays toward the object to form the integrated X-ray beam.

2 . The X-ray emission device of claim 1 , further comprising a phase controller, coupled to the plurality of X-ray emission tubes, for:
controlling duty cycles of the plurality of X-ray emission tubes, such that the plurality of X-ray emission tubes emits the plurality of X-rays in rotation; and when one of the plurality of X-ray emission tubes malfunctions, increasing the duty cycles of the other X-ray emission tubes to maintain illuminance of the integrated X-ray beam.

3 . An X-ray emission device for emitting an integrated X-ray beam toward an object, the X-ray emission device comprising:
a plurality of X-ray emission tubes for respectively generating a plurality of X-rays; a plurality of thermometers, coupled to the plurality of X-ray emission tubes, for respectively measuring a plurality of temperatures of the plurality of X-ray emission tubes; and a controller, coupled to the plurality of thermometers and the plurality of X-ray emission tubes, for controlling duty cycles of the plurality of X-ray emission tubes according to the plurality of temperatures.

4 . The X-ray emission device of claim 3 , wherein the controller is further utilized for disabling one of the plurality of X-ray emission tubes when the corresponding one of the plurality of temperatures exceed a temperature threshold.

5 . The X-ray emission device of claim 3 , further comprising a lens module for guiding the plurality of X-rays toward the object to form the integrated X-ray beam.

6 . The X-ray emission device of claim 5 , wherein the controller is further utilized for:
when the plurality of thermometers indicates that one of the plurality of X-ray emission tubes malfunctions, increasing the duty cycles of the other X-ray emission tubes to maintain illuminance of the integrated X-ray beam.

7 . An X-ray emission device for emitting an integrated X-ray beam toward an object, the X-ray emission device comprising:
a plurality of X-ray emission tubes for respectively generating a plurality of X-rays; and a driving controller, coupled to the plurality of X-ray emission tubes, for controlling a plurality of driving voltages, a plurality of driving currents or a plurality of exposure periods of the plurality of X-ray emission tubes.

8 . The X-ray emission device of claim 7 , further comprising a lens module for guiding the plurality of X-rays toward the object to form the integrated X-ray beam.

9 . The X-ray emission device of claim 8 , wherein the driving controller is further utilized for:
controlling the plurality driving voltages according to an intensity requirement or a penetration requirement of the integrated X-ray beam; or controlling the plurality driving currents or the plurality of exposure periods according to an illuminance requirement of the integrated X-ray beam.

10 . The X-ray emission device of claim 8 , wherein the driving controller is further utilized for:
when one of the plurality of X-ray emission tubes malfunctions, increasing duty cycles of the other X-ray emission tubes to maintain illuminance of the integrated X-ray beam.
