 Abstract: The design and construction of an actively detuned TEM volume transmit/four-channel phased array receive RF system, developed for 4T (170 MHz) magnetic resonance spectroscopic imaging (MRSI) of a human brain, is described. Decoupling between the surface coils in the array is achieved by overlapping the coils, and by utilizing low impedance preamplifiers in combination with quarter wavelength transmission line transformer matching. Peripheral SNR improvement by a factor of 4 - 6 was achieved, as compared to a TEM volume head coil. Results for spectroscopic imaging of a human brain with spatial resolution of 0.125 ml are presented.
