Using the Kyoto-Canon-Optosonics hemispherical imager: the case of a 40-year-old woman with invasive breast cancer, with a 47 mm diameter tumor. First column from left: MR image with lesion marked with red circle. Second column: PA image after eliminating the signals from subcutaneous blood vessels within a depth of 4 mm. Third column: Fusion images of PA (cyan) and MR (red). The PA images demonstrate that tumor associated vasculature converges toward the center of the tumor, tapering drastically at the tumor edge and near the center, where they disappear.
