Abstract
Mini-FDPM is a handheld system for noninvasive breast cancer detection based on frequency domain photon migration. It performs broadband modulation on nearinfrared laser intensity and derives the scattering and absorption coefficients from phase and amplitude measurements. It overcomes many challenges in broadband and optical driver circuitry. Measurements show Mini-FDPM outperforms the current prototype while costing a small fraction. ©2004 IEEE.
