Special input text::

• <image> : will be replaced with slice number (relative number)
• <slice> : will be replaced with slice number (relative number)
• <image_and_max> : will be replaced with slice number and slice max (relative)
• <slice_and_max> : will be replaced with slice number and slice max (relative)
• <slice_pos> : will be replaced by the position of the current slice
• <window> : will be replaced with window value
• <level> : will be replaced with level value
• <window_level> : will be replaced with window and level value
