HT.cost.function: HX.cost.function

In HITXML: Planning tools for ion beam therapy

Description

Computes cost function to be optimized by HX.optimize.field. It depends on the homogeneity of fluence and penalized heavily particle numbers below the minimum limit.

Usage

HX.cost.function( d.mm, focus.FWHM.mm, fluence.cm2, field.size.mm, N.min)

Arguments

d.mm	Value for distance d (in mm).
focus.FWHM.mm	FWHM size of double-Gaussian beam spot (in mm).
field.size.mm	Side length (in mm) of the square field in which homgenous fluence shall be obtained. Actual irradiation field will be bigger.
fluence.cm2	Particle fluence (in 1/cm2) within the homogenous field area.
N.min	Minimal number of particle per raster spot. Given by machine constraints.

Value

Single number.
