Abstract: An apparatus is disclosed for predicting bone fracture risk in an osteoporotic patient. The apparatus comprises a Dual X-ray Absorptiometry scanner for scanning a body area of the patient and producing a Dual X-ray Absorptiometry image of the body area, and image analysis means for analyzing pre-determined aspects of the Dual X-ray Absorptiometry image. The apparatus further comprises data comparison means comprising a database of comparative data sets from Dual X-ray Absorptiometry images of control subjects to predict the risk of bone fracture in the patient. The image analysis means preferably analyses the shape of a body past using an Achieve Shape Model or analyses the texture of a body past using Fourier Transforms and Principal Component Analysis.

Abstract: A semiconductor device which displays an oscillating voltage due to the creation of charge domains which includes a plurality of semiconductor layers and at least two electrodes spaced from one another in the direction of the layers, an upper of which has a composition and/or dimensions predetermined so that a charge therein balances a depletion from a surface charge of the upper layer on application of a potential difference across said electrodes. The electrodes may be in contact solely with the upper layer. A method of manufacturing the device is also provided.
