A garment for real time detection of body deformation during an image scan includes a front portion, made of a compression material and having a plurality of fiber Bragg gratings (FBGs). The garment includes a plurality of light emitters, each light emitter configured to pulse light waves through a corresponding FBGs and a plurality of light sensors, each light sensor attached to a corresponding FBG and configured to receive pulsed light waves. A processor obtains data through a data acquisition module configured to receive from the light sensors peak wavelengths reflected by the FBG Based on the effective shifts of the Bragg wavelengths of the FBGs aligned along the cartesian coordinate system, the processor may correct acquired image data or re-direct an external beam treatment to compensate for body deformation during an image scan.

A wound or incision closure apparatus comprises a first and second panel. Each of the panels comprises a bottom adhesive layer, a medial substrate layer, and an upper load distribution layer which connect the two panels. A sensory or therapeutic element is disposed adjacent, within, or between two or more of the layers. The sensory or therapeutic element can provide sensing and/or therapy for the incision and/or monitor the incision so that the therapy can be customized and updated.

The present disclosure provides a method of evaluating a mechanical property of a material using a device for evaluating the mechanical property of the material. The device comprises a sensing layer having a thickness, a sensing surface and an opposite surface. The sensing layer is deformable such that, when the sensing surface is in direct or indirect contact with the material and a suitable load is applied across both the sensing layer and at least a portion of the material, the sensing layer deforms and the sensing surface moves relative to the opposite surface. The device also comprises a source of electromagnetic radiation in optical communication with the sensing layer. The source is arranged for generating electromagnetic radiation having a coherence length that is of the same order of magnitude as the thickness of the sensing layer or longer than the thickness of the sensing layer. Further, the device comprises a detector for detecting the electromagnetic radiation and being in optical communication with the sensing layer and arranged for receiving the electromagnetic radiation after the electromagnetic radiation is reflected at the interface at the sensing surface of the sensing layer. The method comprises positioning the sensing layer relative to the material such that the sensing surface is in direct or indirect contact with the material. Further, the method comprises applying the suitable load across both the sensing layer and at least a portion of the material whereby the sensing layer deforms and the interface at the sensing surface moves relative to a condition in which no load is applied. The method also comprises directing the electromagnetic radiation to the interface at the sensing surface such that at least a portion of the electromagnetic radiation is reflected at the interface at whereby a first signal is generated and directing electromagnetic radiation along a second optical pathlength to generate a second signal. Further, the method comprises allowing the first signal and the second signal to interfere and detecting an intensity associated with a resultant interference signal using the detector; and determining information concerning the mechanical property of the material from the detected intensity of the interference signal.

A method and system for generating imaging data during a medical intervention are provided. An external optical sensor is attached on the patient's body, and includes at least one external orientation fiber core configured to measure an orientation of the external optical sensor relative to a point of reference. The external optical sensor is interrogated to generate external sensor orientation information during the medical intervention. That information is used to estimate an orientation of the external optical sensor, which is then displayed during the medical intervention.
