Abstract
Gating radioterapija jedna je od metoda liječenja tumora pluća. U ovoj vrsti terapije CT snimanje sinkronizirano je s tretmanom zračenja pomoću disanja pacijenta snimanog sustavom za praćenje disanja pacjenata (imaging sustav). Glavna svrha ovog rada je provjera valjanosti dva imaging sustava, Varian RPM i GateRT, koristeći fantom koji simulira disanje pacjenta. Krivulja disanja fantoma snimana je s oba sustava te su dobivene krivulje uspoređene. Vrijeme reakcije oba sustava izmjereno je te je izračunata razlika između položaja očitanog na gating sustavu i stvarnog položaja fantoma. Krivulja disanja implementirana je u plan zračenja koji je korišten pri zračenju fantoma. Napravljena je film dozimetrija kako bi se dobilo saznanje o passing rates za oba sustava. Vrijeme reakcije oba sustava ne utječe značajno na razliku između stvarnog položaja i položaja koji u tom trenutku snima imaging sustav. Film dozimetrija pokazala je kako je passing rates najviši za breath-hold terapiju. Za terapiju bez breath-holda passing rates nije dovoljno visok kako bi se taj tip terapije preporučio u svakodnevnom liječenju tumora pluća.
Abstract (english)
Gated radiation therapy is a method for lung cancer treatment. In this type of therapy CT imaging and the treatment are synchronized with the patients breathing monitored by imaging systems. The main purpose of this work is the validation of two monitoring systems Varian RPM and GateRT using a homemade gating phantom simulating the patients breathing. The breathing curve of the phantom was recorded with both systems and compared. The reaction time of both systems and the difference between the monitored position and the actual phantom position was calculated. The breathing curve was implemented in the treatment plan used for irradiation of the phantom. During the gated irradiation film dosimetry was used to gain knowledge about the passing rates for each system. The reaction times of both systems do not influence the difference between the monitored position and the actual phantom position significantly. The film dosimetry showed high passing rates for breath-hold therapy. For the gated therapy without breath-hold passing rates are not sufficient to recommend gated therapy in everyday cancer treatment.
