Dual-direction Measuring System of Near Infrared Optical Tomography Combined with X-ray Mammography

This study is to develop a dual-direction measuring instrument of diffuse optical tomography in the continue-wave domain to be incorporated with an X-ray mammography system for the aid of obtaining functional images to detect breast tumors. The device is handled to compress breast-like phantoms by two slabs with sources and detectors which a multiple-channel switching was designed for. Obtained from a dual-direction projection, collaborative information can be benefit for image reconstruction as compared with a single-direction information used. Finally, both simulation data and experimental data are performed to reconstruct functional optical-coefficient images.
