This is a pilot study to look at image quality of iDXA AP supine spinal images to see if the investigators can accurately measure the size of the curve from iDXA images and to see how patients with scoliosis feel about iDXA imaging compared to normal x-rays. With normal x-rays being taken standing (or sitting if patients are in a wheelchair), it is important that the investigators understand how the lying down images compare to the standing images. Where there may be some clinical benefit, images will be taken standing (normal x-rays) and lying down (iDXA images). The investigators will see if the addition of iDXA images can help in brace design and brace monitoring.
