Abstract

Handheld-probe-based optical imagers are a popular approach toward breast imaging because of their potential portability and maximum patient comfort. A novel handheld-probe-based optical imager has been developed and its feasibility for three-dimensional fluorescence tomographic imaging demonstrated. Extensive tomography studies were performed on large slab phantoms ( 650 ml ) to assess the performance limits of the handheld imager. Experiments were performed by using different target volumes ( 0.1 0.45 cm 3 ), target depths ( 1 3 cm ), and fluorescence (Indocyanine Green) absorption contrast ratios in a nonfluorescing ( 1 0 ) and constant fluorescing backgrounds ( 1000 1 to 5 1 ). The estimated sensitivity and specificity of the handheld imager are 43% and 95%, respectively.
