I acquired DTI images using a matrix size of 96x96 with 240mmFOV and 2.5 mm thickness on a Siemens 1.5T. However the resolution of the reconstructed images is 1.875 instead of 2.5mm. My intention was to have isotropic voxels for tractography but it seems the images are interpolated to 128x128 matrix size by default.
Similarly GE 3.0T interpolates to 256x256 by default. It is mentioned in previous posts that one can turn this off by changing the CV rhmethod from '0' to '1' . How can turn off the interpolation on a Siemens 1.5T? Thanks!
