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 system and method for image reconstruction for non-contact ultrasound is provided, where maps or ultrasound images of a subject may be generated without physically contacting the subject. Adjusting or optimizing the photoacoustic excitation system may be performed, such as with beam shaping, surface modifications, or closed-loop automated adjustments. 2D and/or 3D spatial locations of source and receiver laser spots may be used to provide a spatial reference location for ultrasound image reconstruction in a clinically efficacious manner. In addition, point tracking, surface profile characterization, laser adjustments, and/or surface enhancements may be used to facilitate image reconstruction of the subject.
