IMAGE

Data	Type	Description
V	unsigned short	version number
T	8bit unsigned int	Image type (1: Scalar, 3: Vector)
S	8bit unsigned int	Scalar type (2:int8 3:uint8 4:int16 5:uint16 6:int32 7:uint32 10:float32 11:float64)
E	8bit unsigned int	Endian for image data (1:BIG 2:LITTLE) (NOTE: values in image header is fixed to BIG endian)
O	8bit unsigned int	image coordinate (1:RAS 2:LPS)
RI, RJ, RK	16 bit unsigned int	Number of pixels in each direction
PX, PY, PZ	32 bit float	center position of the image
TX, TY, TZ	32 bit float	Transverse vector (direction for 'i' index) / The length represents pixel size in 'i' direction
SX, SY, SZ	32 bit float	Transverse vector (direction for 'j' index) / The length represents pixel size in 'j' direction
NX, NY, NZ	32 bit float	Normal vector of image plane(direction for 'k' index) / The length represents pixel size in 'z' direction or slice thickness
DI, DJ, DK	16 bit unsigned int	Starting index of subvolume
DRI, DRJ, DRK	16 bit unsigned int	number of pixels of subvolume
IMAGE_DATA	Binary image data ()	Image data (endian is determined by "E" field)
