Abstract

One or more example embodiments relates to a method for controlling the temperature of an X-ray device, comprising detecting a heating parameter of a heating element, identifying a target heating parameter for the heating element, and adjusting a fluid supply parameter of a fluid supply unit as a function of a comparison of the heating parameter and the target heating parameter.

Claims (58)

1 . A method for controlling a temperature of an X-ray device, comprising:

detecting a heating parameter of a heating element, wherein the heating parameter characterizes a heat output instantaneously supplied to at least one component of the X-ray device via the heating element;

identifying a target heating parameter for the heating element, wherein the target heating parameter characterizes a heat output to be supplied to the at least one component of the X-ray device via the heating element; and

adjusting a fluid supply parameter of a fluid supply unit as a function of a comparison of the heating parameter and the target heating parameter, wherein

the fluid supply unit is configured to supply a fluid to control the temperature of the at least one component of the X-ray device,

the fluid supply parameter comprises a specification relating to at least one of a fluid temperature or a quantity of fluid to be supplied per unit of time, and

the fluid is supplied by the fluid supply unit based on the adjusted fluid supply parameter.

2 . The method of claim 1 , wherein the heating parameter includes information relating to an instantaneous current to energize the heating element.

3 . The method of claim 2 , wherein

the fluid comprises a gas or gas mixture,

the fluid supply unit includes a fan configured to supply the fluid, and

a rotational speed of the fan is adjusted to adjust a supplied quantity of fluid per unit of time as a function of the fluid supply parameter.

4 . The method of claim 3 , wherein

the X-ray device includes at least one further component,

a temperature control parameter for the at least one further component is identified, the temperature control parameter for the at least one further component characterizes an instantaneous temperature control requirement of the at least one further component,

the fluid supply parameter is additionally adjusted as a function of the at least one temperature control parameter, and

the at least one component of the X-ray device is prioritized with respect to the at least one further component of the X-ray device when adjusting the fluid supply parameter.

5 . The method of claim 4 , wherein the adjusting only adjusts the specification relating to the quantity of fluid to be supplied per unit of time.

6 . The method of claim 5 , wherein the fluid supply parameter is additionally adjusted based on a characteristic over time of the heat output of the heating element.

7 . The method of claim 6 , wherein

the adjusting the fluid supply parameter comprises the specification relating to the fluid temperature and the quantity of fluid to be supplied per unit of time,

the fluid temperature is increased and the quantity of fluid to be supplied per unit of time is reduced if a desired heat output overshoots the instantaneous heat output, and

the fluid temperature is reduced and the quantity of fluid to be supplied per unit of time is increased if the desired heat output undershoots the instantaneous heat output.

8 . The method of claim 1 , wherein

the fluid supply unit includes a temperature control unit configured to control the temperature of the fluid to be supplied, and

temperature control of the fluid to be supplied is adjusted as a function of the fluid supply parameter.

9 . The method of claim 8 , wherein

the fluid supply unit includes a mixing valve configured to add temperature-controlled fluid to a non-temperature-controlled fluid,

the adjusting adjusts a degree of addition of the addition of the temperature-controlled fluid, and

a mixture of the non-temperature-controlled and the temperature-controlled fluid is supplied to the at least one component of the X-ray device.

10 . The method of claim 1 , wherein

the fluid comprises a gas or gas mixture,

the fluid supply unit includes a fan configured to supply the fluid, and

a rotational speed of the fan is adjusted to adjust a supplied quantity of fluid per unit of time as a function of the fluid supply parameter.

11 . The method of claim 1 , wherein

the X-ray device includes at least one further component,

a temperature control parameter for the at least one further component is identified, the temperature control parameter for the at least one further component characterizes an instantaneous temperature control requirement of the at least one further component,

the fluid supply parameter is additionally adjusted as a function of the at least one temperature control parameter, and

the at least one component of the X-ray device is prioritized with respect to the at least one further component of the X-ray device when adjusting the fluid supply parameter.

12 . The method of claim 11 , wherein the adjusting only adjusts the specification relating to the quantity of fluid to be supplied per unit of time.

13 . The method of claim 1 , wherein the fluid supply parameter is additionally adjusted based on a characteristic over time of the heat output of the heating element.

14 . The method of claim 1 , wherein

the adjusting the fluid supply parameter comprises the specification relating to the fluid temperature and the quantity of fluid to be supplied per unit of time,

the fluid temperature is increased and the quantity of fluid to be supplied per unit of time is reduced if a desired heat output overshoots the instantaneous heat output, and

the fluid temperature is reduced and the quantity of fluid to be supplied per unit of time is increased if the desired heat output undershoots the instantaneous heat output.

15 . An X-ray device configured to perform the method of claim 1 , the X-ray device comprising:

a fluid supply unit; and

the at least one component.

16 . The X-ray device of claim 15 , further comprising:

at least one detector element configured to detect incident X-ray radiation as the at least one component which is to be temperature controlled.

17 . The X-ray device of claim 15 , wherein the fluid supply unit includes a temperature control unit configured to control the temperature of the fluid to be supplied as a function of the fluid supply parameter.

18 . The X-ray device of claim 17 , wherein

the fluid supply unit includes a mixing valve configured to add a temperature-controlled fluid to a non-temperature-controlled fluid as a function of the fluid supply parameter, and

the fluid supply unit is configured to supply a mixture of the non-temperature-controlled and the temperature-controlled fluid to the at least one component of the X-ray device.

19 . The X-ray device of claim 15 , wherein

the fluid supply unit has a fan configured to supply a gas or gas mixture as the fluid, and

a rotational speed of the fan is adjustable to adjust the supplied quantity of fluid per unit of time as a function of the fluid supply parameter.

20 . A non-transitory computer program product including program segments, when executed by at least one processing unit, cause the at least one processing unit to perform the method of claim 1 .
