Function Documentation

int imgBranchingCorrection	(	IMG *	image,
		int	mode,
		int	verbose,
		char *	status
	)

Corrects image data for branching fraction (mode=1) or removes correction
(mode=0). Removal is primarily based on branching factor stored in 
IMG struct, secondarily on isotope; after removal, branching factor is
set to 1, and pixel values and calibration factor are multiplied with it.
Correction is based on branching fractions in branch.h; pixel values and
calibration factor are divided by it, and its value is stored in IMG struct.

Note that this function can not know if branching fraction correction is
included in the data (as it usually is) or not.

Returns: Returns 0 if ok.

Parameters

image	Pointer to IMG data
mode	Branching fraction correction (1) or removal of correction (0)
verbose	Verbose level; if zero, then nothing is printed into stdout or stderr
status	Pointer to allocated string where error message will be written; NULL, if not needed.

int imgDecayCorrection	(	IMG *	image,
		int	mode
	)

Corrects (mode=1) or removes correction (mode=0) for physical decay. Removal is based on existing decay correction factors, when possible.

Parameters

image	pointer to IMG data
mode	0=Remove decay correction; 1=Correct for decay

Returns: 0 if ok, 1 image status is not 'occupied', 2 decay already corrected/not corrected, 3 image frame times missing

char* imgIsotope ( IMG * img )

Returns pointer to string describing the isotope in image data

Parameters

img	image stucture

Returns: pointer to string

int imgSetDecayCorrFactors	(	IMG *	image,
		int	mode
	)

Sets (mode=1) or removes (mode=0) decay correction factors in IMG. IMG pixel data is not changed.

Parameters

image	pointer to IMG data
mode	factors are calculated for decay correction (1) or for removing decay correction (0)

Returns: 0 if ok, 1 image status is not 'occupied', 2 invalid exponent value, 3 image frame times are missing
