Test problem used in this simulation study. Total hemoglobin in the tumor was set at 0.04 mM, a 2:1 contrast over the background fibroglandular tissue. Oxygen saturation was 50% in the tumor, and 70% in the background. These values are within the range of contrast found between healthy tissue and invasive ductal carcinomas [1]. Data with 5% white noise in AC amplitude and 5° white noise in phase was generated from this geometry.
