| 摘要 |
<p>A series of images are taken at the site of interest and used to prepare masks of blood vessels and background bone and tissue (PO) and the background bone and tissue only (M). A direct image (IL) of an instrument (30) within a vessel is then acquired and a navigation image is determined (3) by combining the two masks and the direct image with weighting coefficients.
