Abstract
Noncontact sensing of subject motion using Doppler radar within a magnetic resonance imaging (MRI) apparatus transmits a band-pass filtered continuous wave radio signal at a microwave frequency and receives a band-pass filtered reflected radio signal. The subject motion is detected from the received band-pass filtered reflected radio signal using a quadrature radio receiver with a software defined radio implementing Doppler radar. A first antenna, used for transmission and reception, is connected to the quadrature radio using band-pass filters and an RF coupler.…
