Paper Abstract

This paper focuses on breast cancer diagnosis using the newly developed low-noise threewavelength (?=730nm, 805nm and 850nm) NIR light emitting diode (LED) continuous-wave (CW) imager. The NIR CW imager has its advantage of simplicity, and potential for a portable instrument. The imaging rate is 5 frame/second. The signal to noise ratio is larger than 2000 when measuring at a breast model ( ?a=0.04/cm, ?'= 8/cm), which corresponds to 4x 10-4 optical density (OD) error. Phantom test was carried out, and indicated good localization of heterogeneity. It was known that cancer has more blood concentration and de-oxygenation than normal tissue, which is the principle of breast cancer detection using NIR spectroscopy. Clinical results of breast cancer studies will be presented. Keywords: LED, Breast Cancer Imaging, CW
