PHYSICAL PRINCIPLES OF NUCLEAR MAGNETIC RESONANCE. These simulations demonstrate the theoretical results from our design and it shows the designed antenna behaviour. In this step, finally the parameters are readjusted to obtain our desired Larmor frequency (298,2MHz) for a correct operation in 7T.
Secondly, the results obtained with this simulator are introduced to the CST Microwave Studio, creating a 3D model and generating a simulation. In this project thesis, for obtain the design, a study is carried out firstly using the computer program BirdcageBuilder (developed by the Penn State Hershey collage of Medicine). It opens the door to design and construct a Birdcage coil for a 7T to obtain human brain images. In this project is designed a Birdcage coil for a 7T to obtain images from small animals (like a mouse). The birdcage coil achieves circular polarization and generates a high homogeneous radio frequency magnetic field under many conditions. For this reason, it is interesting research with high fields. Moreover, a better SNR increases the spatial resolution or reduces the imaging time.
More strength field has a better SNR and increased chemical shift effects, improving spectral fat suppression and spectroscopy. Concretely, the principal objective is the design of a birdcage coil (RF coil) to use in a 7 Tesla scanner. This work describes the study of coil for Magnetic Resonance Imaging (MRI) application.
