Abstract
The present invention provides an apparatus and a corresponding method useful for electron paramagnetic resonance imaging, in situ and in vivo, using high-isolation transmit/receive (TX/RX) coils, which, in some embodiments, provide microenvironmental images that are representative of particular internal structures in the human body and spatially resolved images of tissue/cell protein signals responding to conditions (such as hypoxia) that show the temporal sequence of certain biological processes, and, in some embodiments, that distinguish malignant tissue from healthy tissue. In some embodiments, the TX/RX coils are in a surface, volume or surface-volume configuration. In some embodiments, the transmit coils are oriented to generate an RF magnetic field in directions substantially orthogonal to a static gradient field, and the receive coils are oriented to sense RF EPR signal in directions substantially orthogonal to the transmitted field and to the static field, to minimize coupling of the transmitted signal to the receive coils.
