A method and a system for carrying out visual queries with respect to e.g. neurobiological structures, wherein - in particular neuronal - data are stored in a database (12) and computer means (10) comprising visualization means (14) are provided for visualization of such structures and data, whereby in a preprocessing step (19), for volume elements of a region of interest, a respective distance table (27; 27') is calculated, said distance table comprising pairs of structure distance values (d) and structure IDs (id), and on the basis of said distance table, an associated look-up table (LUT) is established which contains a count of the pairs (d, id) as well as an offset of the row in the distance table, said look-up table being apt to be kept in a runtime memory (16'), wherein rapid access to data via the respective look-up table and the corresponding distance table may be performed. |
