Abstract

In this paper we report simulation results on combined imaging by simultaneously deploying an ultrasound transducer and NIR source detector fibers on a ring probe. Compared with the reflection geometry, the advantage of transmission geometry for NIR imaging is the reduced target dynamic range in depth. We show in the paper that with the aid of a priori target geometry information provided by co-registered ultrasound, NIR reconstruction of absorption coefficient can be improved from 30% to 85%.
