Abstract
An X-ray system (10) includes an X-ray tube (16) that has a temperature sensor (22) coupled thereto. The temperature sensor (22) may be included in a heat exchanger (18). The temperature sensor (22) generates a temperature signal that is provided to a controller (12). The controller (12) generates a fan speed control signal that is used to control the speed of the fan (20) in response to the temperature signal.
Claims20
An x-ray system comprising:
- an X-ray tube temperature sensor generating a temperature signal;
- and
- a fan coupled to said temperature sensor, said fan having a speed that varies in response to said temperature signal.
A CT system comprising:
- an X-ray tube;
- a heat exchanger coupled to the X-ray tube;
- a temperature sensor generating a temperature signal;
- a fan coupled to said temperature sensor, and
- a controller generating a fan speed that varies in response to said temperature signal.
2 more elements
A method of operating an X-ray system comprising:
