Möjligheten att visualisera olika sjukdomstillstånd med hjälp av bilder har inom sjukvården blivit mer och mer populärt. Nuklearmedicinska bilder framställs genom att en liten mängd av ett radioaktivt ämne injiceras i patienten och sedan detekteras med hjälp av en gammakamera. Genom att utnyttja olika upptagsmekanismer kan funktionen av ett område eller ett specifikt organ i kroppen undersökas. BlThe purpose of this work is to assess the activity level needed to achieve satisfactory diagnostic information in regional cerebral blood flow single photon emission computed tomography (rCBF SPECT) by introducing a new evaluation method to be used for and hopefully facilitate optimization studies in nuclear medicine in the future. The purpose is further to perform a visual grading study and inves

Before a processing unit is taken into production it is prepared with water instead of product, among other things it is sterilized this way. When this preparation phase is done, the water is pushed out with the product that is about to be processed. During this phase a mixed zone of water and product occurs. This mixed zone of water and product results in a cost for the producing company due to l
