Method for recording magnetic resonance image data when using a ventilation apparatus
First Claim
1. A method for recording magnetic resonance image data of a patient ventilated by means of a ventilation apparatus, comprising:
- assigning influencing information describing an effect of a respiratory movement on quality of the magnetic resonance image data to pulse sequence information;
determining a magnetic resonance protocol for actuating a magnetic resonance device and a ventilation protocol for actuating the ventilation apparatus and coordinating with one another in time taking into account the pulse sequence information together with the influencing information, an imaging objective and a ventilation requirement; and
actuating the magnetic resonance device and the ventilation apparatus in a time-coordinated manner on the basis of the magnetic resonance protocol and the ventilation protocol,wherein the magnetic resonance device is actuated for recording the magnetic resonance image data in layers according to a sequence, andwherein the sequence of the layers is determined based on the effect of the respiratory movement on the quality of the magnetic resonance image data such that some of the layers are recorded during movement phases where the respiratory movement has less effect on the quality of the magnetic resonance image data and some of the layers are recorded during ventilation pauses where the respiratory movement has more effect on the quality of the magnetic resonance image data.

Abstract
A method for recording magnetic resonance image data of a patient ventilated by means of a ventilation apparatus is provided. The method includes assigning influencing information describing the effect of a respiratory movement on the image data recording to pulse sequence information, determining a magnetic resonance protocol for actuating a magnetic resonance device and a ventilation protocol for actuating the ventilation apparatus, and coordinating with one another in time, taking into account the pulse sequence information together with the influencing information, an imaging objective and a ventilation requirement, and actuating the magnetic resonance device and the ventilation apparatus in a time-coordinated manner on the basis of the magnetic resonance protocol and the ventilation protocol.

16. An examination system, comprising:
-
a magnetic resonance device having a first control device; a ventilation apparatus having a second control device; and a communications link, between the first and second control devices, wherein the first control device and/or the second control device are embodied for performing a method, and wherein the method comprises; assigning influencing information describing an effect of a respiratory movement on quality of the magnetic resonance image data to pulse sequence information; determining a magnetic resonance protocol for actuating a magnetic resonance device and a ventilation protocol for actuating the ventilation apparatus and coordinating with one another in time taking into account the pulse sequence information together with the influencing information, an imaging objective and a ventilation requirement; and actuating the magnetic resonance device and the ventilation apparatus in a time-coordinated manner on the basis of the magnetic resonance protocol and the ventilation protocol, wherein the magnetic resonance device is actuated for recording the magnetic resonance image data in layers according to a sequence, and wherein the sequence of the layers is determined based on the effect of the respiratory movement on the quality of the magnetic resonance image data such that some of the layers are recorded during movement phases where the respiratory movement has less effect on the quality of the magnetic resonance image data and some of the layers are recorded during ventilation pauses where the respiratory movement has more effect on the quality of the magnetic resonance image data.
