McXtrace: Absorption_sample

[ Identification | Description | Input parameters | Links ]

The Absorption_sample Component

Sample component with absorbing materials.

Identification

  • Site:
  • Author: Erik B Knudsen
  • Origin: Risoe
  • Date: March 2011

Description

A sample component consisting of a volume of one material and volume of another
material inside. This is useful as a phantom for simulating tomography experiments.
The inner material can be left unset (all 0), to only have one volume.

Sample shape may be a cylinder, a sphere, a box or any other shape
box/plate:       xwidth x yheight x zdepth
cylinder:        radius x yheight
sphere:          radius (yheight=0)
any shape:       geometry=OFF/PLY file

Input parameters

Parameters in boldface are required; the others are optional.
