Summary
• Point Kernel algorithms show small deviations versus
Monte Carlo for clinical cases, much more accurate than
Pencil Kernel models
• Collapsed Cone inherent paralellism can efficiently use
Graphical Processor Units for dose calculations literally in
seconds
• Accuracy (and speed...) implemention dependent,
depending on the approximations used
• Pencil kernel algorithms frequently used instead of point
kernels, particularly in applications with optimizations, but
will give errors particularly for lung cases
