and 3.0of the neutron ray tracing package - developed for
Risø and later
DTU Physics
in
collaboration with NBI,
KU,
PSI
and
ILL
d3view - 3D visualisation package for brain images -
developed for Neurobiology Research
Unit. The 'Viden
om' TV show on science has had two features
about brain imaging and brain
surgery once available in REAL video format in which d3view is
used for visualisation. Also used for front cover illustrations in
Neuroimage
(1),
(2),
(3).
Simulation package for investigating parameter significance in
tomographic imaging - for my masters thesis
PSD4SC
-
host of infrastructure for European software collaboration on single crystal diffraction with
neutrons.
