Medical imaging apparatus, control method, and computer program product

1. A medical imaging apparatus comprising:

an X-ray imaging apparatus including an X-ray tube configured to emit X-rays for generating an X-ray CT image;

a nuclear medicine imaging apparatus including a detector configured to detect radiation for generating a nuclear medicine image;

a changing unit configured to change at least one of an emission direction and an emission width of the X-rays so that the X-rays are incident on the detector; and

a determining unit configured to determine whether the detector detects the X-rays, thereby determining whether there is a failure in the detector.

2. The medical imaging apparatus according to claim 1 ,

wherein the X-ray tube is configured to emit the X-rays while being rotated about a space in which an examinee is arranged.

3. A control method comprising:

allowing an X-ray tube to emit X-rays for generating an X-ray CT image;

allowing a detector to detect radiation for generating a nuclear medicine image;

changing at least one of an emission direction and an emission width of the X-rays so that the X-rays are incident on the detector; and

determining whether the detector detects the X-rays emitted by the X-ray tube, thereby determining whether there is a failure in the detector.

4. A non-transitory computer readable medium comprising instructions that cause a computer to execute:

allowing an X-ray tube to emit X-rays for generating an X-ray CT image;

allowing a detector to detect radiation for generating a nuclear medicine image;

determining whether the detector detects the X-rays emitted by the X-ray tube, thereby determining whether there is a failure in the detector,

wherein at least one of an emission direction and an emission width of the X-rays is changed so that the X-rays are incident on the detector.

5. The medical imaging apparatus according to claim 1 ,

wherein the changing unit is a scatterer configured to be arranged in a direction in which the X-ray tube emits the X-rays and scatters the X-rays.

6. The medical imaging apparatus according to claim 5 ,

wherein the scatterer is made of a metal material.

7. The medical imaging apparatus according to claim 5 ,

wherein the scatterer is a sphere.

8. The medical imaging apparatus according to claim 5 ,

wherein the scatterer is a polyhedron.

9. The medical imaging apparatus according to claim 5 ,

wherein the scatterer has an angle such that the X-ray is not scattered to outside of the detector.

10. The medical imaging apparatus according to claim 1 ,

wherein the changing unit is a collimator of the X-ray tube.
