Patients with medical implants are often unable to receive magnetic resonance imaging (MRI) diagnostic treatment, because the conductive leads can concentrate the RF excitation field and generate dangerous heating of nervous tissue. We propose a simple, low-cost solution that minimizes RF heating through the addition of one or more mutually coupled filars to the lead without significant increase in...
A description is given of an MRI (magnetic resonance imaging) instrumentation system, and the advantages of a distributed processing approach to its implementation are discussed. Some of the functions are described, and it is shown that local intelligence in each of the units is essential. The decomposition of such complex instrumentation problems can ease the implementation and enables equipment...
