We present interferometric images of the Sunyaev-Zel'dovich effect for the high redshift (z > 0.5) galaxy clusters in the Einstein Medium Sensitivity Survey: MS0451.5-0305 (z=0.54), MS0015.9+1609 (z=0.55), MS2053.7-0449 (z=0.58), MS1137.5+6625 (z=0.78), and MS 1054.5-0321 (z=0.83). Isothermal beta models are applied to the data to determine the magnitude of the Sunyaev-Zel'dovich decrement in each cluster. Complementary ROSAT PSPC and HRI x-ray data are also analyzed, and are combined with the S-Z data to generate an independent estimate of the cluster distance. Since the Sunyaev-Zel'dovich Effect is invariant with redshift, sensitive S-Z imaging can provide an independent determination of the size, shape, density, and distance of high redshift galaxy clusters; we will discuss current systematic uncertainties with this approach, as well as future observations which will yield stronger constraints.
