Static Coil Design Considerations for the Magnetic Resonance Imaging
One of the main challenges in developing magnetic resonance imaging (MRI) systems is to create a static coil that needs to generate magnetic field density along with the characteristics of optimal homogeneity and magnitude size. To do this, two N42 Block PMs are used and the iron core is designed and optimized in accordance with the dimensions of PM pieces using ANSYS Maxwell software. Then, al...
متن کاملQuantitative T 2 Magnetic Resonance Imaging
The exceptional soft tissue contrast of which MRI benefits, makes it an important tool for medical diagnosis. Not only the contrast itself, but also the possible quantification of relaxation times T 1 and T 2 causing this contrast is of interest. This quantification has proven to be clinically useful in the context of neurological diseases such as schizophrenia, autism, Parkin-son's disease and...
متن کاملFetal magnetic resonance imaging at 3.0 T.
Magnetic resonance imaging (MRI) has been used to image the in utero fetus for the past 3 decades. Although not as commonplace as other patient-oriented MRI, it is a growing field and demonstrating a role in the clinical care of the fetus. Indeed, the body of literature involving fetal MRI exceeds 3000 published articles. Indeed, there is interest in accessing even the healthy fetus with MRI to...
متن کاملFeasibility of magnetic resonance redox imaging at low magnetic field: comparison at 1 T and 7 T.
The effect of different static magnetic field strengths, 1 T or 7 T, on the quality of nitroxyl radical-based magnetic resonance redox imaging (MRRI) was examined. A stable nitroxyl radical, 3-methoxycarbonyl-2,2,5,5-tetramethylpyrrolidine-N-oxyl (MC-PROXYL), was used as a T1 contrast agent. Phantoms and animals were scanned at 1 T and 7 T using a similar gradient echo sequence. The quality of ...
