IMAGE PROCESSING METHOD, IMAGE PROCESSING SYSTEM, AND X-RAY COMPUTED TOMOGRAPHY SYSTEM |
摘要 |
<p>Disclosed is image processing: that significantly reduces false images and missing images in reconstructed images, and improves reconstruction accuracy; and that can be applied to objects to be observed that are composed of a plurality of components, and to samples having an unknown number of structural compositions. An image processing device is provided with: a means, in an electron microscope having an imaging device and a tilting device that tilts an object to be observed, for tilting said object to be observed in an angle step, and storing the obtained tilted image; a means for aligning the position of said tilted image; a means for generating an initial reconstructed image based on said tilted image; a means for projecting said initial reconstructed image at arbitrarily-defined angles and generating a plurality of projected images; a means for calculating errors in the corresponding pixels between the tilted image and the projected images; a means for determining the processing priority from said errors; a means for calculating the density for each gradation level; a means for determining the processing priority from said densities; and a means for changing the density value of each pixel in the initial reconstructed image according to each of the abovementioned priorities.</p> |
