Simulator nadzornega sistema protonske terapije za testiranje pospeševalnika delcev

LONČAR, ALJAŽ (author), Beguš, Samo (mentor)

Kontrolni sistem protonske terapije je sestavljen iz več podsistemov, kjer vsak podsistem opravlja svojo funkcijo. Med razvojem, testiranjem in nastavljanjem pospeševalnika vsi podsistemi še niso vzpostavljeni, zato se nadzorni sistem protonske terapije simulira. V delu je opisan simulator nadzornega sistema za protonsko terapijo z enakimi funkcionalnostmi, kot nadzorni sistem za protonsko terapijo. Simulator je prilagodljiv na različne sisteme pospeševalnikov in nudi fleksibilnost pri poimenovanju OPC UA spremenljivk za povezavo na uporabniški vmesnik. Znotraj simulatorja so integrirani asinhroni časovniki za vzdrževanje in nadzor komunikacije s kontrolnim sistemom pospeševalnika. Simulator ves čas simulira nadzorni sistem protonske terapije in daje ukaze kontrolnemu sistemu pospeševalnika. Uporabnik upravlja simulator z uporabniškim vmesnikom, simulator pa na uporabniškem vmesniku prikazuje trenutno stanje simulatorja in kontrolnega sistema pospeševalnika.

• Title: Treatment control system simulator for testing particle accelerator

Abstract

Control system of the proton therapy machine cosnists of many sub-systems such as treatrment control system and accelerator control system. During the develoment and testing phase of the accelerator control system it is not neccecary to have all sorounding components ready. In such cases simulators are used. This thesis describes simulator of treatment control system capable of controlling the accelerator control system in the same way as the treatment control system.The simulator is configurable and can be used for different particle accelerators. It also provides flexible OPC UA data-point names which are used to connect to the user interface. Simulator integrates asynchronous timers for supervising a communication between simulator and an accelerator control system. Simulator exposes its status and status of the accelerator control system via OPC UA data-points. User interface allows users to define treatment parameters and controls the accelerator control system.
