Hi user !!!!
I´m very in doubt !!!!
I have a stack of axial CT image
x = 512
y = 512
Z = 81
space x = 1
space y = 1
space z = 13.65
How can i caculate my new stack in Z when i Rotate Y
by 64 degrees
i try
double ZExtent =
80.00/sin(1.11);
//90-64 degrees
spaceZ = 13.65 / sin(1.54-1.11);
spaceZ = sqrt( pow( (13.65 * 80), 2 ) +
pow( spaceZ, 2 ) ) / ZExtent ;
then
SetOutputSpacing( 1.00, 1.00, spaceZ );
Is right ????
Tanks a lot for help me !!!!!!1
