Abstract
A breast diffusion optical tomography (DOT) device includes a light source, a detector, a mechanical driver and a contour acquisitor without using optical fiber and reduce the system complexity. The light source includes M1 number of multi-wavelength near-infrared light emitters for a continuous-wave mode and M2 number of laser diodes of different wavelengths for a frequency-domain mode. The detector includes N1 number of silicon photomultipliers for detecting near-infrared light in the continuous-wave mode and N2 number of silicon photomultipliers for detecting near-infrared light in the frequency-domain mode. The mechanical driver adjusts a distance between the light source and the detector. The contour acquisitor obtains the geometry of a patient's breast for reconstruction. The DOT device uses amplitude and phase information obtained in the frequency-domain mode to estimate initial optical parameters of tissues and then apply for reconstruction in the continuous-wave mode.
