5 Ways The Spectrum Is Revolutionizing Medical Care By Paul Kruczkowski, editor
The medical electronics industry is transforming the way health providers administer care, both through the development of new technology and by finding new applications for existing technology. As a preview to the MD&M (Medical Design & Manufacturing) West event (Feb. 11–14; Anaheim, CA), here are five innovative ways the electronic design community is using the frequency spectrum, RF to near-IR (NIR), to advance medicine.

This year, the MD&M West 2013 conference has been revamped and redesigned to include themed tracks, each reflecting the key stages of medical device development. These include design and prototype, validation, testing and trials, regulatory submissions and approval, and post-market compliance and production. Register here.
A Four-Element 'Clover' Transceiver Array For 3 Tesla Cardiac MRI By Shumin Wang and Hai Lu, EM Software & Systems
The design of radio frequency (RF) coils is of paramount importance to the quality and safety of magnetic resonance imaging (MRI). Being the signal generator and detector of MRI, RF coils are required to generate a uniform excitation in the target during transmission and high signal-to-noise ratio (SNR) during reception. In the meantime, RF coils must not cause subject overheating in in-vivo human studies. This requires that RF energy deposited inside the human body and coupled to receivers should be minimized.
High-voltage resistive ink banding is applied using our patented banding process (for Pi configurations). (US Patent 7,212,394 B2) With this process we are able to withstand 3,000 VDC Hi-Pot Breakdown required for defibrillation monitoring and medical diagnostic equipment. Download a datasheet.
Meridian Medical Systems develops products that use microwave energy to generate heat, measure radiation and motion, and monitor and maintain the temperature of blood and other fluids. This application note discusses how AWR Microwave Office’s software was recently used to develop an accurate feedback mechanism for cardiac arrhythmia.
This download contains information on Huber + Suhner's RF components for medical system diagnostics. Corrugated cables, fiber optic connectors, hermetically sealed components, nonmagnetic coaxial connectors, and nonmagnetic coaxial cables are included.
With high sensitivity and short switching time, this low capacitance photodiode is ideal for use in a variety of medical diagnostic applications. The surface mount packaging allows for easy and convenient integration into new or existing systems.
Remcom has created a demonstration showing how easily a complex structure such as a birdcage coil can be created in XF7. Those customers experienced in older versions of XFdtd will appreciate the improvements XF7 offers; others that may be unfamiliar with XFdtd will learn how the editing features work and the relative ease with which complex structures can be created within the software without the need of an external CAD resource.
