rdd.model: Radial dose distribution (rdd) models

In libamtrack: Computational Routines for Proton and Ion Radiotherapy

Description

In libamtrack, there are currently seven parametrizations of distribution of local dose around particle track as a function of the primary particle's energy and type. They are referred to using sequential positive integer numbers (see details).

Details

The implemented rdd models are:

rdd.model	description
1	A simple test function (constant over entire track width/electron range)
2	Point target rdd proposed by Butts and Katz (Butts & Katz, 1969)
3	Simplified extended target rdd proposed by O. Geiss (Geiss, 1997)
4	Simplified extended target rdd proposed by Katz (Katz et al., 1972)
5	Point target rdd proposed by Cucinotta (Cucinotta, XXXX)
6	Extended target rdd proposed by Katz (Katz, XXXX)
7	Extended target rdd proposed by Cucinotta (Cucinotta, XXXX)

The corresponding rdd parameters are:

rdd.model	rdd.parameters[1]	rdd.parameters[2]	rdd.parameters[3]
1	NA	NA	NA
2	minimal radius (integration limit) [m]	lower dose cut-off [Gy]	NA
3	core diameter/target size [m]	NA	NA
4	core diameter/target size [m]	lower dose cut-off [Gy]	NA
5	minimal radius (integration limit) [m]	lower dose cut-off [Gy]	NA
6	minimal radius (integration limit) [m]	core diameter/target size [m]	lower dose cut-off [Gy]
7	minimal radius (integration limit) [m]	core diameter/target size [m]	lower dose cut-off [Gy]

The corresponding default values are:

rdd.model	rdd.parameters[1]	rdd.parameters[2]	rdd.parameters[3]
1	NA	NA	NA
2	1e-10	1e-10	NA
3	5e-8	NA	NA
4	5e-8	1e-10	NA
5	5e-11	1e-10	NA
6	1e-10	1e-8	1e-10
7	5e-11	1e-8	1e-10
