Improvement and Restoration of Biomedical Images Blurred by Body Movement

Abstract

The restoration of biomedical images that have been blurred due to body movement are discussed. The observation system for these images is described using a mathematical operator and coordinate transformations. And a band-suppressed restoration filter composed of a series of such operators is proposed for improving the quality of images. In addition, redundancy is introduced into these restoration filters in order to suppress additive noise, The proposed method is applied to blurred X-ray images of a bone model of the elbow joint. The optimum position and number of markers, which are attached to the subject as a reference signal, are also discussed.
