Abstract :
The imaging reconstruction of near infrared (NIR) diffusive light is in general underdetermined and ill-posed. We have proposed a novel combined approach by using a priori knowledge acquired from co-registered ultrasound to overcome the NIR inversion problem. In this paper we report simulation and experimental results on combined imaging, and we show that NIR reconstruction with the aid of co-registered ultrasound is well defined and the reconstructed optical properties are more accurate than NIR imaging alone.
