METHOD AND APPARATUS FOR REAL TIME RESPIRATORY GATING SIGNAL GENERATION AND DETECTION OF BODY DEFORMATION USING EMBEDDED FIBER BRAGG GRATINGS

Japanese Patent JP2023166389

A

To provide a method of correcting body deformation during image acquisition.SOLUTION: 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.SELECTED DRAWING: Figure 2A
