| This logic is needed as an intermediate step to get from 2D images to a 3D volume. In order to reconstruct the full volume we need to know the relationship between the images (projections) we have - how they are located in 3D relative to each other. | This logic is needed as an intermediate step to get from 2D images to a 3D volume.

| In case any reference model for the particle is available, it can be used as 'anchor set' that would increase the precision of the output. | In case any reference model for the particle is available, it can be used as 'anchor set' that would increase the precision of the output. | ||
| - | However, when no prior model is available for the particles of interest, determination of [[https://en.wikipedia.org/wiki/Euler_angles|Euler angles]] should be done de novo.
