Abstract :
Mini-FDPM is a handheld system for noninvasive breast cancer detection based on frequency domain photon migration. It performs broadband modulation on near-infrared 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.
