Quantitative modeling of specific absorption rate and temperature rise within the human body during 1.5 T and 3 T MRI scans is of clinical significance to ensure patient safety. This research work demonstrates the theoretical results from our design and shows the designed antenna behavior. Finally the parameters are re adjusted to obtain our desired Larmor frequency 298.2 MHz for a correct operation in 7T. Firstly we design a birdcage coil then the results are obtained with simulator CST Wave Studio, creating a 3D model and generating a simulation. It opens the door to design and construct a Birdcage coil for a 7T to obtain human brain images. Design of a Birdcage coil for a 7T to obtain the images from s mall animals (i.e. The birdcage coil achieves circular polarization and generates a high homogeneous radio frequency magnetic field under many conditions.

This research work presented recent developments based on high field 7T design using CST studio. Moreover, a better SNR increases the spatial resolution or reduces the imaging time.

Higher strength field generates a better SNR and increased chemical shift effect, improving spectral fat suppression and spectroscopy. The principal objective is the design of a birdcage Radio Frequency (RF) coil to use in a 7 Tesla (7T) scanner. This work describes the study of coils for Magnetic Resonance Imaging (MRI) applications.
