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.

Abstract: A method and associated system for designing a biomechanical interface of a device contacting a biological body segment of a subject includes forming a quantitative model of the biological body segment from subject specific data, conducting a biophysical analysis, such as a finite element analysis, to thereby establish a relationship, such as a functional relationship, between the quantitative model and at least one feature of the biomechanical interface contacting the biological body segment, and applying the relationship to the at least one feature of the biomechanical interface contacting the biological body segment to thereby obtain an interface design for the mechanical interface of the device. The subject-specific data can include geometry of the biological body segment and the at least one feature can be associated with physiological benefit of the biological body segment.
