Abstract :
Near-infrared (NIR) optical spectroscopy has shown promising diagnostic capability for early detection of breast cancer. Our aim is to miniaturize existing technology and develop a suitable device for bedside monitoring. A NIR based handheld imager is a compact and can be a cost effective complimentary solution to the existing technologies like X-ray mammography and ultrasound. The device is a continuous-wave imager with SNR of 46 dB that monitors the changes in blood volume and oxygenation. Data are displayed on the handheld device using a dynamic color-coding scheme, which enhances the contrast in images. Preliminary analyses have been done using breast phantom and cuff ischemia experiment. Further experiments on a breast model with tumor will be performed. Then, preliminary clinical results will be presented.
