  1. The processing time of intensity inhomogeneity correction for 10 three-dimensional T1-weighted MRI scans was measured using the "time" command in Linux.
  2. *VMware player was executed on 64 bit Windows 7 platform with core i7 L640 (4 cores) with 4GB RAM, but the number of cores and RAM size were reduced to 2 and 1GB, respectively, due to constraints of the emulation mode.
