Example command line operation:
Suppose that your CD-ROM drive is E, if your CD-ROM is mapped to another
drive letter, substitute that letter in all of the commands hereafter.
Example (1)
Use the ShrinkMR program to reduce the size of the MRI volume.
A. Make a directory on your hard disk for the resulting shrunk volume.
md C:\pgu\ch20\data
Note: the name of the hard disk directory is arbitrary.
B. Switch the current directory to the executable directory on the CD:
cd E:\ch20\exe
C. Run the program with the command line:
ShrinkMR E:\ch20\data\MRI.DAT c:\pgu\ch20\data\MRI2.DAT
Note: this command uses the default name for shrunken volume.
Example (2)
Use the Display program to visualize the shrunk and window and leveled
CT volume as described in the chapter.
A. Switch the current directory to the executable directory on the CD:
cd E:\ch20\exe
B. Run the program with the command line:
Display C:\pgu\ch20\data\CT3.DAT 256 gray.lut
Note: this assumes you have created the CT3.DAT volume using the
ShrinkCT and WinLev programs as described in the chapter.
Example (3)
Use the Hist8 program to show the Histogram of the 8 bit MRI volume.
A. Switch the current directory to the executable directory on the CD:
cd E:\ch20\exe
B. Run the program with the command line:
Hist8 C:\pgu\ch20\data\MRI3.DAT
Note: this assumes you have created the MRI3.DAT volume using the
ShrinkCT and WinLev programs as described in the chapter.
