A four-channel phased array consisting of one surface coil, two
endorectal coils, and one flexible endourethral loop coil was
designed for MRI of the canine prostate. The endorectal coils
provide high signal in the posterior region of the prostate, while
the endourethral and surface coils are sensitive to the central
and anterior regions of the prostate. Gel phantom experiments
indicate that the proposed phased-array configuration gener-
ates 15 times more signal-to-noise ratio (SNR) than a combina-
tion of two surface coils and one endorectal coil within the
posterior region of the prostate; the performance of the two
configurations is comparable near the anterior prostate sur-
face. Ultimate intrinsic SNR (UISNR) analysis was used to com-
