Design and Testing of a Radiofrequency Ellipsoidal Helmholtz Coil in Contrast with a Circular Pair for Nuclear Magnetic Resonance
نویسندگان
چکیده
The design and testing of a Helmholtz prototype probe with relatively homogeneous radiofrequency field that can be used for MRI are presented in this paper. It consists two coaxial separately tuned ellipsoidal rings wire symmetric arrangement. developed structure is tested experimentally free space compared the results obtained an equivalent circular standard coil. Complete electrical modeling coils taking into account all couplings (inductive capacitive) studied. proposed coil provides better performance terms homogeneity, efficiency, quality factor. width lobe at 10% 20% bigger. Moreover, significant improvement factor observed space. Also, efficiency increased by 37%. Finally, Signal to Noise Ratio (SNR) higher than

Designing and Fabrication of a New Radiofrequency Planar microcoil for mini-Nuclear Magnetic Resonance
Introduction Radiofrequency planar microcoils are used to increase the resolution of magnetic resonance images of small samples. In this study, we aimed to design and fabricate a spiral planar microcoil constructed on a double-sided printed circuit board (PCB). It has four rings with an internal diameter of 241 microns tuned and matched at 63.8 MHz. Materials and Methods To achieve the maximum ...
متن کاملStatic 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...
