Abstract: A proximity-coupled loop antenna. The proximity-coupled loop antenna includes a dielectric substrate, a ground plane having a direct-fed strip cut therefrom, a radio frequency port, a coupled strip cut therefrom, a first edge cut therefrom parallel the direct-fed strip and a second edge cut therefrom adjacent the first edge situated on the dielectric substrate, the first and second edges of the ground plane having a total length of approximately one-quarter wavelength of the lowest resonant frequency of the antenna and forming a conductive resonant edge.

Abstract: An improved system for providing audio signals to a patient during medical imaging is disclosed. A converter device is operatively connected to a audio signal transmitter such as a pneumatic audio port commonly used for pneumatic headphones. The converter device includes a connecting member removably inserted into the pneumatic audio port. A microphone receives the pneumatic audio signals and converts these signals to electronic audio signals. The converter device further includes a wireless transmitter that converts the electronic audio signals to wireless signals and transmits the wireless signals to a wireless receiver. The wireless receiver may be located in a headset worn by the patient, which receives the wireless signals and provides the audio content to the patient during imaging.
