A mechanism for mapping an anatomical characteristic of a patient includes a treatment bed having a top surface. A fiber Bragg grating channel is disposed along at least a portion of the treatment bed near the top surface and includes a fiber optic waveguide defining a plurality of spaced-apart Bragg-type gratings. A multi-wavelength light source generates a beam that is in optical communication with the fiber Bragg grating channel. A detector, in optical communication with the fiber Bragg grating channel, detects reflections of light from at least one of the Bragg-type gratings. A computer is programmed to calculate at least one anatomical characteristic based on a characteristic of at least one of the reflection of light.
