- class pytomography.metadata.PET.pet_tof_metadata.PETTOFMeta(num_bins, bin_width, fwhm, n_sigmas=3, bin_type='symmetric')[source]#
Class for PET time of flight metadata. Contains information such as spatial binning and resolution.
- Parameters:
num_bins (int) – Number of bins used to discretize time of flight data
bin_width (float) – Bin width of time of flight bins in mm.
fwhm (float) – FWHM corresponding to TOF uncertainty in mm.
n_sigmas (float) – Number of sigmas to consider when using TOF projection. Defaults to 3.
bin_type (str, optional) – How the bins are arranged. Currently, the only option is symmetry, which means the bins are distributed symmetrically (evenly on each side) between the center of all LOR pairs. Defaults to ‘symmetric’.
