Abstract

We implemented a ring-scanning mechanism in a prone diffuse optical imaging (DOI) system for the application of breast tumor detection before. In the study, simultaneous multiple-sinusoids driving light source and flexible opto-measurement channels were considered to update the DOI system. The designed flexible channels in the scanning module of imaging system prevent optical information loss measured on a noncircular phantom/object if using fixed optical channels. Further, simultaneous multiple-sinusoids driving light sources speed up the acquisition of optical information for the frequency domain DOI. Examination phantoms were designated to justify the proposed measurement schemes.
