A computer-implemented method of detecting and quantifying a spinal curve is disclosed herein. The method comprises obtaining a Forward-Looking Infrared Radiometer (FLIR) camera, calibrating the FLIR camera to room temperature, stabilizing the FLIR camera for imaging of a spine of a subject at a position horizontally spaced about ½ to about 3 meters, or about ½ to about 2 meters, from the camera, scanning at least a portion of the spine with the FLIR camera to obtain thermal data, and generating an image of the subject's spine. Corresponding systems and methods also are disclosed.
