Simulacija pretoka krvi po vratnih žilah

BENKO, PETER (avtor), Divjak, Saša (mentor), Marolt, Matija (komentor)

Cilj te diplomske naloge je pregled širokega področja obstoječih rešitev za simulacijo pretoka fluida po tridimenzionalnem modelu, uporaba najprimernejše v spletni aplikaciji, z vizijo, da se jo vpne v obstoječi program Med3D. Simulacijo želimo pognati po modelu žile, pridobljenim iz postopka sestavljanja medicinskih slik v programu NeckVeins. V nalogi v grobem spoznamo tudi fizikalno ozadje načina simulacije po mrežni Boltzmannovi metodi, na kateri sloni knjižnica, ki smo jo izbrali po pregledu področja. Spoznamo načine zapisov podatkov, ki so potrebni za uspešno povezovanje vmesnikov obstoječih programov. Predstavljena je končna implementacija programa, ki smo ga razvili, algoritmi, uporabljeni za pomoč pri obdelavi modela, ter odločitve pri snovanju programa.

Izvleček

The goal of this thesis is an overview of the vast field of existing computational fluid dynamics solvers for a three-dimensional model and integration of the most suitable into a web application, with the vision to integrate it into the existing Med3D program. The simulation is to be run through a blood vessel, that was generated by assembling medical images in NeckVeins. In the paper we get briefly acquainted with the physical background of the Lattice Boltzmann method, on which the chosen solution from the overview of existing solutions is based on. We inspect the file formats, that are needed for a successful integration of different interfaces, that the existing software already defines. Presented is also the final implementation of the developed program, the algorithms used for supporting the preparation of the model for the simulation, and design decisions met during the development.
