MIT engineers have devised a new technique to detect either electrical activity or optical signals in the brain, using a minimally invasive technique based on magnetic resonance imaging (MRI).

How does EMI differ from RMI? What types of EMI and EMC affect medical devices? Shielding options. Dealing with computed-tomography interference. The medical circumstance for many people requires that ...

Current medical guidelines have prompted implementation of increasing numbers of implantable rhythm devices, be they pacemakers, internal cardioverter–defibrillators or loop recorders. These devices ...

Steps in the physical simulation process in efforts to mitigate EMI. How a one-stage EMI filter can help suppress EMI. Electronic equipment will typically have some immunity to electromagnetic ...

Electromagnetic (EM) shielding creates a barrier that prevents interference from strong EM fields that could be harmful to sensitive electronic devices and live organisms. This review focuses on the ...
