| titleOfInvention | Configuration for nuclear magnetic resonance imaging (MRI) with an MRI phantom |
| abstract | An MRI configuration comprising a magnet system for generating a homogeneous magnetic field, a radio frequency (RF) system ( 105 ) for generating/detecting an RF field B 1 , and a gradient system ( 106 ) for temporarily superposing defined gradient fields on a magnetic field B 0 , and an MRI phantom ( 104 ) positioned in the volume under investigation, wherein the MRI phantom ( 104 ) comprises a chamber ( 1 ) disposed in a housing ( 2 ) and filled with a liquid, in which a gas bubble ( 3 ) forms, wherein the liquid contains nuclei which have an NMR relaxation time T 1 , of between 100 ms and 20 s, is characterized in that the chamber ( 1 ) of the MRI phantom ( 104 ) comprises a main chamber ( 4 ) and a partial chamber ( 5 ), wherein the main chamber ( 4 ) is delimited from the partial chamber ( 5 ) such that the gas bubble ( 3 ) can completely enter the partial chamber ( 5 ) due to its buoyancy by changing the spatial orientation of the MRI phantom ( 104 ) in the gravitation field, and remains in the partial chamber ( 5 ) in a measurement orientation of the MRI phantom ( 104 ) due to its buoyancy. This eliminates imaging artefacts despite the presence of a gas bubble. |
