If I want to use rtkLagCorrectionImageFilter for correction, are there any materials I can refer to?How can I obtain the parameters for:

-a, --rates=FLOAT Lag rates (a0, a1, a2, a3)

-c, --coefficients=FLOAT Lag coefficients (b0, b1, b2, b3)

In the online documentation, you’ll find some information about the references on which this is based. These parameters are scanner specific and are usually obtained from calibration measurements, e.g., illuminating the detector for some time then switching off the x-rays and measuring the lag in the following frames.

The scatter correction algorithm is based on the work of
[Boellaard, Rad Onc, 1997]. It assumes a homogeneous contribution of scatter
which is computed depending on the amount of tissues traversed by x-rays.

I would like to study this method but cannot locate the paper referenced in this code.Do you have the full text of the paper? Could you send me a copy

I think the technical details are in [Boellaard, Med Phys, 1997]. The doc has been updated recently

I think his main point was absence of publicly available full text of the article, not the exact citation.
