Abstract: Devices and methods for obtaining external shapes and internal tissue geometries, as well as tissue behaviors, of a biological body segment are provided. A device for three- dimensional imaging of a biological body segment includes a structure configured to receive the biological body segment, the structure including a first array of imaging devices disposed about a perimeter of the device to capture side images of the biological body segment and a second array of imaging devices disposed at an end of the device to capture images of a distal portion of the biological body segment. The second array has a generally axial viewing angle relative to the perimeter. A controller is configured to generate a three-dimensional reconstruction of the biological body segment based on cross-correlation of captured images from the first and second arrays.
