发明名称 Method for improved correction of spectrum hardening artifacts in computed tomography images
摘要 The method disclosed herein includes the steps of providing a computed tomography image having a base component, a first component of a first material, and a second component of a second material, the first and second materials causing beam hardening artifacts, segmenting the image into different sections, each section containing one of the artifact-causing components, calculating thickness of components in one of the sections, calculating a correction factor to compensate for artifacts created by the artifact-causing component in the section, and adding the correction factor to the image and additionally, the providing step may include the step of providing raw image data, which can then be converted into image data representative of the computed tomography image.
