Torakālās aortas modeļa izveide no datortomogrāfijas uzņēmumiem un asins plūsmas modelēšana tajā

subject

OpenFOAM Fizika asins plūsmas simulācija pacientam specifiska režģa ģenerēšana aortas aneirisma

description

Torakālās aortas aneirisma diagnosticēšanai izmanto vispārējus aortas parametrus, ar ku- riem nevar noteikt mazāk ekstrēmus, toties letālus, slimības izpausmes gadījumus. Darba mērķis ir izveidot modeli asins plūsmas aprēķinam torakālajā aortā izmantojot reālu pacientu datorto- mogrāfijas uzņēmumus un OpenFOAM atvērtā koda šķidrumu dinamikas rīkkopu. Darbā tika izveidots automātisks algoritms un izstrādāta metodika ģeometrijas apgabala un skaitliskā hidro- dinamikas režģa iegūšanai no aortas datortomogrāfijas uzņēmumiem. Izmantojot izveidoto režģi, tika veikta asins plūsmas modelēšana stacionārā un dinamiskā režīmā, piemeklējot piemērotākus robežnosacījumus pētāmajam apgabalam.
