The term voxel refers to "volumetric pixel" thus giving you some virtual representation of a 3D cube and refers to the notion of doing a fully 3D Monte-Carlo simulation (contrary to some pseudo variants and hybrids). Size and discretisation of the voxels allow you to adapt the Monte-Carlo simulation accuracy and its computing time. From my experience, the term is rather general and does not refer to any specific field. Yet, a famous area of application is truly the medical branch.

Best regards, yours Marcus
