FCC Approval of Finite Element Method for Biomedical Transmitters Puts ANSYS Software in the Spotlight
PITTSBURGH, March 3, 2011 /PRNewswire/ -- For specific electromagnetic applications in the healthcare industry, HFSS™ software from ANSYS  (Nasdaq: ANSS ) can now provide proof that a biomedical device transmitter design meets Federal Communications Commission (FCC) standards -- a ruling that will enable medical device developers to cut development time and costs while meeting safety standards.
The FCC ruled in February that the finite element method (FEM) is a valid technique to simulate a medical device that must communicate with other similar devices. As a result, organizations in the medical equipment sector can use HFSS -- industry-leading FEM electromagnetic field simulation -- to validate their transmitter designs.
Today’s sophisticated medical implants and other equipment often contain transmitters that communicate with other devices -- transferring physiological data to a doctor via wireless communication, for example, which can be used to monitor, diagnose or treat a patient’s condition. The new FCC ruling applies to transmitters that are placed inside, on, or in close proximity to the human body. Developers of such medical devices must ensure that their equipment meets radio frequency (RF) emission safety standards. Additionally, manufacturers must comply with specific absorption rate (SAR) regulations, a measure of how the body absorbs energy when exposed to an RF electromagnetic field. HFSS software -- which employs FEM simulation to verify both SAR and RF emissions -- can also reduce development time and costs while increasing reliability and design optimization.
“The HFSS finite element solution is extremely valuable for designing antenna systems for implantable devices,” said Mark Lanciault, principal electrical en
