A dynamic frequency domain tomography imaging system has been developed for pressure-enhanced breast imaging with data acquisition times less than 15 sec. The amplitude and phase data at three wavelengths, 660, 785 & 826nm, are acquired simultaneously and used for reconstructing images of total hemoglobin (HbT), blood oxygen saturation (StO2) and water concentrations in breast. The results of a homogenous blood phantom study indicate that the percent errors of average estimated chromophore values are less than 8% compared with the true values. Crosstalk between the channels in simultaneous acquisition mode resulted in error increases of 6.3% to 7.6% and 3% to 8% over data acquired in sequential mode.
