Abstract

U ovom radu proučena je problematika analiziranja podataka u pozitronskoj emisijskoj tomografiji. Proučeni su načini tumačenja podataka, te izrađene skripte za dotično tumačenje. Rastumačene su forme ulaznih podataka dobivenih od stroja, te su one pretvorene u razumljiviji oblik. Podaci su pripremljeni za provedbu napredne metode rekonstrukcije slike. Razvijena je i primijenjena napredna metoda rekonstrukcije slike bazirana na compressive sensing metodi. Podaci su tijekom višestrukih provođenja metode pomno promatrani, te su sve nepravilnosti ispravljane pri radu. Na kraju, provedena je analiza dobivenih rezultata te izvedeni zaključci o trenutnom stanju i plan za daljnje razvijanje i poboljšanje metode.

Abstract (english)

In this paper the problem of analyzing data in positron emission tomography was studied. The modes of interpreting of the data were studied and scripts for the given interpreting were made. The forms of input data given by machine were explained and transformed into more understanding form. Data were prepared for applying advanced method of image reconstruction. The advanced method for reconstruction based on compressive sensing was developed and applied. Data were closely examined during the multiple runs of the method, and all irregularities were removed in the process. In the end, the analysis of given results was made and conclusions about current status and a plan for upcoming development and improvement of the method were developed.
