Abstract :
The authors have successfully demonstrated 3-D high-resolution real-time in vivo imaging by the miniature MEMS-scanner based DAC (dual-axes confocal) probes in both form-factors (10 and 5-mm diameter) by acquiring reflectance and fluorescence images. From the obtained high quality images, the DAC microscope shows great potential to substantially enhance clinical imaging practice by permitting sub-surface 3-D in vivo real-time imaging. When coupled with fluorescence markers targeted against a variety of diseases, the microscope will enable on-table-management with in vivo real-time optical biopsy for early and accurate detection of cancer resection.
