This study aims at the design, implementation, and verification of a near infrared (NIR) diffuse optical tomography (DOT) electro-optical imaging system based on a measuring instrument with scanning mechanism of synchronous multi-point detection and an image reconstruction scheme implemented on an off-line PC. The developed measurement instrument possesses a high degree of angular resolution and can be operated in a continuous-intensity or intensity modulation scheme to acquire output NIR radiance signals. Experimental trials are conducted using both homogeneous and heterogeneous phantoms made of high-scattering Intralipid. Promising results have been obtained with a superior spatial resolution, especially for absorption image, compared with the system with fixed number of detection channels.
