Embodiment Construction

[0041] figure 1 A schematic diagram of a magnetic resonance apparatus 1 according to the invention is shown. As is generally known, the magnetic resonance apparatus 1 has a main magnet unit 2 , which is shown here in dashed lines and defines a cylindrical patient receptacle 3 . A high frequency coil arrangement (bodycoil body coil) and a gradient coil arrangement can be provided around the patient accommodation 3 as is basically known;

[0042] A patient 5 positioned on the patient table 4 can be moved into the patient receptacle 3 via the patient table 4 to perform a magnetic resonance examination, ie to perform a magnetic resonance imaging. If the magnetic resonance imaging is carried out in the region of the abdomen and / or chest of the patient 5 , it should be noted that this region is influenced by the respiratory movement of the patient 5 . The respiration of the patient 5 is therefore also to be measured here, for which the magnetic resonance system 1 has a correspondi...

Abstract

A method is provided for measuring the breathing of a patient during a magnetic resonance examination with a magnetic resonance device, wherein the reflection properties of at least one coil element arranged beneath the patient are measured and evaluated to determine the breathing data that describes the respiratory situation at various times.

Description

technical field [0001] The invention relates to a method, a measuring device and a magnetic resonance apparatus for measuring a breathing process of a patient during a magnetic resonance examination. Background technique [0002] Magnetic resonance imaging is currently used especially in the medical field. Here, the patient is exposed to a strong magnetic field, ie the basic magnetic field or B0 field, so that spin alignment occurs. By high-frequency excitation, the aligned spins can be excited and the decay of this excitation is measured as a magnetic resonance signal. Gradient fields are used to achieve spatial resolution. [0003] In magnetic resonance examinations, a possible source of error or cause of artifacts is patient motion. Since the magnetic resonance imaging requires a certain duration, it is also important that the patient lies flat without moving during the entire duration of the magnetic resonance examination. This assumption is not possible when examini...
