Decay correction factor

WebDecay correction factor is defined as an attribute on the instance level in PET modality image. Biograph acquires PET whole-body scans in a step-and-shoot fashion, the entire axial imaging range of the body is covered by a discrete set of beds acquired at evenly spaced axial positions at different times. WebNow we can use that decay_correction_factor (lambda,t1,t2) computes duration/ (int_t1^t2 exp (-lambda t)) That leads to the formula below (as it turns out that the above ratio only depends t2-t1) */ const double duration = frame_defs.get_duration (1); const double decay_corr_factor = decay_correction_factor (isotope_halflife, 0., duration);
