Decay Correction

Provides functions for undo-ing decay correction and recalculating it.

Classes

DecayCorrect	Decay correct or uncorrect each frame in a dynamic PET scan.
DecayFix	Special case for decay correction where the dynamic PET image was scaled with the wrong

Functions

undo_decay_correction(→ ants.ANTsImage)	Uses decay factors from the metadata for an image to remove decay correction for each frame.
decay_correct(→ ants.ANTsImage)	Recalculate decay_correction for nifti image based on frame reference times.
calculate_frame_decay_factor(→ numpy.ndarray)	Calculate decay correction factors for a scan given the frame reference time and half life.
scale_frames(input_img, scalar_arr)
