Abstract

Hip implants, pacemakers, and other metal implants can cause considerable distortions in computerized axial tomography computed tomography (CT) or computerized axial tomography scans. This distortion can lead to misdiagnoses, which can have fatal consequences. We have developed a novel technique using linear algebra to remove these distortions from CT images. Through a selective removal of intensity data, we are able to eliminate the distortions while maintaining high resolution in 64 x 64 pixel images.
