tomodrgn.dose.calculate_critical_dose_per_frequency#

calculate_critical_dose_per_frequency(spatial_frequencies: ndarray, voltage: int) → ndarray[source]#

Calculate critical dose for spatial frequencies following Grant and Grigorieff 2015

Parameters:

  • spatial_frequencies – numpy array of spatial frequency at each pixel (units 1/Å), shape (D, D), dtype float

  • voltage – scalar of voltage of electron source in kv, dtype int

Returns:

numpy array of critical dose for each spatial frequency, shape (D, D), dtype float
