CST – Computer Simulation Technology

Advanced System Simulation for Multichannel MRI Coils

Magnetic Resonance Imaging (MRI) has gained a lot in popularity in medical diagnoses over the past years thanks to the advantages it offers over other imaging techniques. The complex overlay of magnetic fields at frequencies from static to HF makes field simulation - even including circuit based tuning - an essential and integral part of the design and optimization process of the complete MRI system. CST Studio Suite®, with its complete technology approach, is ideally suited to this task. Knowledge of the field distribution inside the body is crucial for the patient's safety. Since measurement of these internal fields is impossible, electromagnetic simulation can give the MRI system designer invaluable insight. Improved image quality can be achieved with the new generation of high-field MRIs, but the price of the related higher operating frequencies is that even more stringent technical challenges are introduced. These typically have to be addressed by using multi-channel coils. Using real-world examples, this eSeminar will give an overview of the complete MRI workflow including coil-design, circuit-based tuning, multi-channel optimization, and dedicated post-processing such as full system SAR and bio-heat evaluation.
