Situación de la estimación del NTCP
Storyboard
En las zonas de tejido sano en que se logra evitara la radiación de múltiples direcciones el problema de la anisotropia puede ser mayor. En dicha situación se puede trabajar con múltiples simulaciones en que se rota la geometría de la grilla. El nivel que esto resulte necesario va a depender de la precisión que se busca alcanzar en la estimación del NTCP.

Problems of anisotropy
Description
The fact that it favors only some directions according to the grid that is defined plays a subordinate role in what is the application of the LBM in the hydrodynamic case. This is because the relaxation process smoothes the effects of the anisotropy by distributing the particles in all directions uniformly. This can be very different in the case of radiotherapy where there may be privileged directions.

Situation of the NTCP estimates
Description
In areas of healthy tissue where multiple-direction radiation is avoided, the problem of anisotropy may be greater. In this situation it is possible to work with multiple simulations in which the geometry of the grid is rotated. The level that this is necessary will depend on the accuracy that is sought to reach in the estimation of the NTCP.

Situation of the TCP estimations
Description
This means that in the calculation of the dose the fact that is treated in a multidirectional way will help to reduce the problem in the area of the tissue to be irradiated. Therefore, in the calculations of the TCP it is convenient to consider the sum of the radiations of multiple directions before propagating the energy in the surrounding tissue.
