Abstract

According to one embodiment, an X-ray diagnostic apparatus includes an X-ray tube, a driver, a supporter, and processing circuitry. The X-ray tube including a rotating anode. The driver rotates the rotating anode. The supporter supports the X-ray tube in an inclinable manner. The processing circuitry acquires information indicating an attitude of the supporter and controls the driver based on information indicating the acquired attitude.

Claims (56)

1. An X-ray diagnostic apparatus, comprising:

an X-ray tube including a rotating anode;

a driver that rotates the rotating anode;

a supporter that supports the X-ray tube in an inclinable manner; and

processing circuitry configured to:

acquire information indicating an attitude of the supporter; and

control the driver based on information indicating the acquired attitude.

2. The X-ray diagnostic apparatus according to claim 1 , wherein

the processing circuitry is further configured to:

control the driver based on a rotation frequency associated with the acquired attitude.

3. The X-ray diagnostic apparatus according to claim 1 , wherein

the processing circuitry is further configured to:

control the driver based on a voltage waveform associated with the acquired attitude.

4. The X-ray diagnostic apparatus according to claim 1 , further comprising:

a memory that stores the acquired attitude and a parameter relating to the control of the driver in association with each other.

5. The X-ray diagnostic apparatus according to claim 1 , wherein

the processing circuitry is further configured to:

collect sounds generated from the X-ray tube; and

determine whether or not a result of the collection exceeds a threshold value; and

reset a parameter relating to the control of the driver based on a result of the determination.

6. The X-ray diagnostic apparatus according to claim 5 , further comprising:

a memory that stores the acquired attitude and the reset parameter in association with each other.

7. The X-ray diagnostic apparatus according to claim 1 , wherein the processing circuitry is further configured to reset a parameter relating to the control of the driver in response to an operation by a user.

8. An X-ray diagnostic apparatus, comprising:

an X-ray tube including a rotating anode;

a driver that rotates the rotating anode;

a supporter that supports the X-ray tube in an inclinable manner; and

processing circuitry configured to:

set an attitude of the supporter; and

a memory that stores the set attitude of the supporter in association with a parameter used to control the driver.

9. The X-ray diagnostic apparatus according to claim 8 , wherein

the processing circuitry is further configured to:

collect sounds generated at the time of anode boosting of the X-ray tube in the set attitude, and

the memory stores information indicating whether or not a result of the collection exceeds a threshold value, in association with the set attitude.

10. The X-ray diagnostic apparatus according to claim 9 , wherein

the processing circuitry is further configured to:

change the parameter stored in the memory based on whether or not a result of the collection exceeds a threshold value, and

the memory stores the attitude and the changed parameter in association with each other.

11. The X-ray diagnostic apparatus according to claim 8 , wherein

the parameter includes a rotation frequency.

12. The X-ray diagnostic apparatus according to claim 8 , wherein

the parameter includes a voltage signal.

13. The X-ray diagnostic apparatus according to claim 8 , wherein

the processing circuitry is further configured to:

acquire information indicating an attitude of the supporter; and

control the driver based on information indicating the acquired attitude and the parameter stored in the memory by referring to the memory.

14. An X-ray high-voltage generator for an X-ray diagnostic apparatus comprising

an X-ray tube with a rotating anode,

a driver that rotates the rotating anode, and

a supporter that supports the X-ray tube in an inclinable manner, the X-ray high-voltage generator comprising:

processing circuitry configured to:

acquire information indicating an attitude of the supporter; and

control the driver based on information indicating the acquired attitude.

15. The X-ray diagnostic apparatus according to claim 1 , wherein the processing circuitry configured to control the driver based on the information indicating the acquired attitude is configured to control the driver based on a rotation frequency associated with the acquired attitude to avoid resonance in the supporter at the acquired attitude.

16. The X-ray diagnostic apparatus according to claim 8 , wherein the parameter used to control the driver comprises a parameter to avoid resonance in the supporter at the attitude of the supporter.

17. The X-ray high-voltage generator according to claim 14 , wherein the processing circuitry configured to control the driver based on the information indicating the acquired attitude is configured to control the driver based on a rotation frequency associated with the acquired attitude to avoid resonance in the supporter at the acquired attitude.
