<div style="RIGHT: auto">I am working on project that is about slice to volume registration.</div>
<div style="RIGHT: auto">I wrote a code by Mathlab. The code works in such a manner:</div>
<div style="RIGHT: auto">we have a slice(for example an image of heart), and initial guess where this image is located in the cube or volume, the initial guess is defined by means of rotation and translation of the center of the cube.</div>
<div style="RIGHT: auto">we have a function that define the difference between images(Metric function). as such as we have smaller difference, we will find better match, So the problem is an optimization problem to find the minimum.</div>
<div style="RIGHT: auto"> I used the functions from optimization toolbar of mathlab and implemented the code.</div>
<div style="RIGHT: auto">The code works very well on data that I loaded from matlab(load mri),</div>
<div style="RIGHT: auto">but it does not work at all on other data that I have. It is CT data that I take it from my advisor.</div>
<div style="RIGHT: auto">Sombody can haelp me what is the problem?<VAR id=yui-ie-cursor></VAR> </div></div></body></html>
