Abstract

Claims (36)

1. A method for adjusting a driving force for moving a patient table of a magnetic resonance apparatus, the method comprising:

determining position-relevant and/or drive-relevant patient data;

determining, using a controller, a minimum required driving force based on the position-relevant and/or drive-relevant patient data;

adjusting, using an adjuster, the minimum required driving force to move the patient table; and

control, using the controller, a drive to move the patient table with the minimum required driving force.

2. The method as claimed in claim 1 , wherein the position-relevant and/or drive-relevant patient data comprises:

a weight of a patient;

a size of the patient; and/or

an orientation and/or positioning of the patient on the patient table.

3. The method as claimed in claim 1 , wherein the position-relevant and/or drive-relevant patient data comprises data of a patient registration.

4. The method as claimed in claim 1 , wherein determining the position-relevant and/or drive-relevant patient data comprises acquiring, using a camera and/or a sensor, the position-relevant and/or drive-relevant patient data.

5. The method as claimed in claim 1 , further comprising:

identifying, based on a movement of the patient table, a power required by the patient table; and

identifying, based on the identified power required by the patient table, an occurrence of a dangerous situation during the movement of the patient table.

6. The method as claimed in claim 5 , wherein, in response to the occurrence of a dangerous situation during the movement of the patient table, generating a warning message and providing the generated warning message to a user.

7. The method as claimed in claim 5 , wherein, in response to the occurrence of a dangerous situation during the movement of the patient table, stopping the movement of the patient table.

8. The method as claimed in claim 7 , wherein a manual confirmation input is required for the movement of the patient table to be resumed.

9. The method as claimed in claim 7 , further comprising:

determining, based on the required amount of power, an increased driving force for a resumed movement of the patient table.

10. The method as claimed in claim 1 , further comprising generating a user output and outputting the generating the user output to the user before time-critical magnetic resonance examinations.

11. A non-transitory computer-readable storage medium with an executable program stored thereon, that when executed, instructs a processor to perform the method of claim 1 .

12. A magnetic resonance apparatus comprising:

one or more processors; and

memory storing instructions that, when executed by the one or more processors, configure the apparatus to:

determine position-relevant and/or drive-relevant patient data;

determine a minimum required driving force based on the position-relevant and/or drive-relevant patient data;

adjust the minimum required driving force to move a patient table; and

control a drive to move the patient table with the minimum required driving force.

13. A magnetic resonance apparatus adapted to adjust a driving force for moving a patient table, the apparatus comprising:

a patient receiving area;

a scanner at least partially surrounding the patient receiving area;

a patient table configured to move a patient into the patient receiving area;

a provisioning unit configured to provide position-relevant and/or drive-relevant patient data;

a computer configured to determine a minimum required driving force based on the position-relevant and/or drive-relevant patient data;

an adjuster configured to adjust the minimum required driving force at the patient table; and

a patient table travel unit configured to move the patient table.
