AT.CPPSC.alpha.and.beta

Share:

Description

Returns alpha and beta for an ion survival curve predicted by the CPPSC model. The arguments are directly passed on to the AT.run.CPPSC.method routine, some are provided default values here to simplify the use. !! THIS ROUTINE IS LIMITED TO THE LIN-QUAD MODEL BUT SHOULD BE GENERALIZED FOR ANY GAMMA REPONSE, BOTH IN TERMS OF INPUT X RAY PARAMETERS *AND* OF RETURNED (FITTED) ION PARAMETERS!! Cave: Even if input X ray response is LQ with cut dose, the resulting LQ will be purely linear-quadratic without high-dose linear characteristic.
