Hi Everyone,

I want to rotate a 3D image around a specific point (not in center point). Below is a code that I used imrotate3, and it was rotated around center point

DoseSimulated = imrotate3(DoseSimulated,XrotSAG,[1,0,0],'cubic','crop');

DoseSimulated = imrotate3(DoseSimulated,YrotCORO,[0,1,0],'cubic','crop');

DoseSimulated = imrotate3(DoseSimulated,ZrotTRAN,[0,0,1],'cubic','crop');

where DoseSimulated is 3D dose image (it is a medical image), and XrotSAG, YrotCORO, ZrotTRAN are corresponded rotation degree about X axis, Y axis, Z axis.

Can anyone know how can I solve it.

Thanks for your reading thru.
