Abstract: The dynamic positioning of sensors, which exploit the mechanical and physiological changes in tissues, can significantly increase the performance in characterization of tumors. Here, we disclose the Optical Dynamic Imaging (ODI) System for tumor characterization. ODI System estimates size, depth, elastic modulus and optical properties of embedded objects. The ODI System consists of a tactile imaging sensor (TIS), and a near infrared diffuse spectral imaging. To obtain mechanical properties of the target, we compress the region of interest with the probe, then the light from the probe is scattered and captured by the camera as a tactile image. On the other hand, using a light source and the camera as a detector, we obtain the diffuse spectral images. From these images, we compute the absorption coefficient of the embedded tumor phantom. We move the source-detector simultaneously and collect optical information. We termed this maneuver as dynamic positioning. Optical Dynamic Imaging System also provides position and orientation of the light source and the detectors. The combination of the absorption coefficient and tactile data along with location information improves the size, depth, and elastic modulus estimation.

Abstract: A tactile sensor, computer readable medium, methods of using and manufacturing the tactile sensor, and methods and apparatuses for processing the information generated by the tactile sensor. The tactile sensor includes a planar optical waveguide comprised of a flexible and transparent layer, a light configured to direct light into the optical waveguide; a light sensor or an imager facing the optical waveguide and configured to generate signals from light scattered out of the optical waveguide; and a controller which may be configured to generate an image of the object and characteristics of the object. The waveguide may be configured so that some of the light directed into the optical waveguide is scattered out of the waveguide if the waveguide is deformed by being pressed against the object. A finite element and a neural network are used to estimate mechanical characteristics of the objects.

Abstract: A mobile-platform imaging device uses compression of the target region to generate an image of an object. A tactile sensor has an optical waveguide with a flexible, transparent first layer. Light is directed into the waveguide. Light is scattered out of the first layer when the first layer is deformed. The first layer is deformed by the tactile sensor being pressed against the object, A force sensor detects a force pressing the tactile sensor against the object and outputs corresponding force information. A first communication unit receives the force information from the force sensor. A receptacle holds a mobile device with a second communication unit and an imager that can generate image information using light scattered out of the first layer. The first communication unit communicates with the second communication unit and the mobile device communicates with an external network.
