Dear Sir/Madam

I am running DICOM example with data from CT for head. The geometry is 110 layer with 128x128 voxels for each layer and the dimension of voxels are (2.01562mm, 2.01562mm, 1mm). The following error is happens with some initial seed numbers and program hangs in this format. As it is clear the problem happens in the voxel around the origin of local point. Please help me to get ride of this problem.

Track stuck or not moving.
          Track stuck, not moving for 10 steps
          in volume -phantom- at point (1.17148,-1.36137e-10,-170) (local point (0.163671,1.00781,-0.5))
          direction: (0.0296006,4.86496e-05,0.999562) (local direction: (0.0296006,4.86496e-05,0.999562)).
          Potential geometry or navigation problem !
          Trying pushing it of 1e-07 mm ...Potential overlap in geometry!
