Utveckling av modulbaserad 11C-processutrustning inom PET
Presentation av idéer och koncept
This report describes the planning and the accomplishment of the final diploma workat the study program Mechanical Engineering, Department of Engineering Sciences, Uppsala University. Two students carried out the diploma work at GE HealthcareHusbyborg in Uppsala.The aim of the diploma work was to develop and improve existing processequipment for 11C-radiochemistry in PET. The process equipment was to be dividedinto smaller independent modules to make it more flexible. Part of the existingprocess equipment is an oven that is supposed to perform a specific chemicalreaction. One of the main goals was to study and improve this oven.The work could be divided into three main phases: 1.Present concepts for one module, and interface between different modules. 2. Analyze and choose components for the module mentioned above. 3. Present concepts for the oven, which is placed in the module mentioned above.At the beginning, user requirements were listed in cooperation with the mentor. Later, components available on the market and the existing process equipment wereanalyzed. A product function analysis of the oven was made to show its function and design.The concept phase was mainly about brainstorming to generate ideas. Later, hybridization was used as a method to combine different ideas. Then two prototypeswere built and tested. The test results showed which idea seemed to be the best.Different concepts were assessed and put into a concept selection matrix, after which the best was chosen and developed further.
