Hi, <br><br>I'm a student trying to fight against DICOM ugly registries. Using MATLAB and MIPAV I've been trying to realize how to calculate the Transformation Matrix in order to find an absolute Voxel position from a relative one. I red that DICOM (0020,0037) registry and from that i understood that it's information provides the directions cosines from x and y. from MIPAV and a certain image i got this example:
<br><br>(0020,0037) = 0.9966044465, 0, -0.08233827028, -0.005859506527, 0.99746231, -0.0709551988.<br><br>And the MIPAV calculates the next matrix:<br><br>0,9966 -0,0059 0,0821 0,0000<br>0,0000 0,9975 0,0712 0,0000<br>-0,0823 -0,0710 0,9941 0,0000
<br>0,0000 0,0000 0,0000 0,0000<br><br>As u can see, the first to columns are those described in the (0020,0037) registry, but the third one is being calculated in a mysterious way.</blockquote><div><br>cross product of the first 2 .
