Objective: In this study, it was aimed to calculate and compare organ doses of male and female pediatric phantoms in the same age group applied whole body tomography using Monte Carlo method. Materials and Methods: The simulation was performed on a GE Discovery CT750 HD model tomography instrument with a tube voltage of 100 kVp, a current irradiation time of 100 mAs and a dose index (CTDI) of 5,31 in the VirtualDose program. Five groups of anatomic phantoms called new born, 1, 5, 10 and 15 years old, as stated in the ICRP-89 report for male and female phantoms in the same age group, were used. Results: The total effective dose was found 13.92, 12.28, 11.70, 10.31 and 8.82 for new born, 1, 5, 10 and 15 years old groups, respectively. New born group male phantom testes dose was found 14.08 mGy, female phantom ovaries dose was found 13.05 mGy. In the 1 year old group male phantom testes and prostate doses were found 14.92 and 12.24 mGy, female phantom ovaries and uterus doses were found 12.44 and 10.98 mGy, respectively. In the 5 year old group male phantom testes and prostate doses were found 14.33 and 12.53 mGy, female phantom ovaries and uterus doses were found 11.65 and 10.25 mGy, respectively. In the 10 year old group male phantom testes and prostate doses were found 13.69 and 10.80 mGy, female phantom ovaries and uterine doses were found 9.51 and 8.50 mGy, respectively. In the 15 year old male phantom doses of brain, colon, liver, stomach, testes, thyroid, adrenal, gall bladder, kidney, pancreas, prostate, small intestine, spinal cord, spleen, thymus were found 8.81, 8.51, 8.60, 8.22, 12.43, 12.76, 7.36, 7.44, 8.49, 6.88, 7.88, 9.84, 7.42, 8.48, 8.45, 8.56 mGy, female phantom doses of brain, colon, liver, stomach, ovaries, thyroid, adrenal, gall bladder, kidney, pancreas, uterus, small intestine, spinal cord, spleen, thymus were found 9.30, 10.45, 9.34, 9.41, 7.95, 14.66, 7.85, 8.33, 10.10, 8.39, 8.86, 6.88, 9.11, 9.03, 9.48, 9.32 mGy. Conclusion: There was no sex-dependent difference in total effective dose in 5 groups. Male phantom testes doses in 5 groups were found higher than female phantom ovarium doses. There is no significant difference in organ doses of newborn, 1, 5, 10 year old male and female phantoms out of 15 year old.

Amaç: Bu çalışmada, Monte Carlo yöntemi kullanılarak tüm vücut tomografi uygulanan aynı yaş grubundaki erkek ve kız pediatrik fantomları üzerinden organ dozlarının hesaplanması ve karşılaştırılması amaçlanmıştır. Materyal ve Metot: Simülasyon VirtualDose programında, tüp voltajı 100 kVp, akım ışınlama süresi 100 mAs, doz indeksi (CTDI) 5,31 olan GE Discovery CT750 HD model tomografi cihazına göre yapılmıştır. Aynı yaş grubundaki erkek ve kız pediatrik fantomları için ICRP-89 raporunda belirtilen yeni doğan, 1, 5, 10 ve 15 yaş olmak üzere 5 grup anatomik fantom kullanılmıştır. Bulgular: Total efektif doz değeri yeni doğan, 1, 5, 10 ve 15 yaş grubu için sırasıyla 13.92, 12.28, 11.70, 10.31 ve 8.82 bulundu. Yeni doğan grubunda erkek fantom testis dozu 14.08 mGy, kız fantom ovaryum dozu 13.05 mGy bulundu. 1 yaş grubunda erkek fantom testis ve prostat dozları 14.92 ve 12.24 mGy, kız fantom ovaryum ve rahim dozları 12.44 ve 10.98 mGy bulundu. 5 yaş grubunda erkek fantom testis ve prostat dozları 14.33 ve 12.53 mGy, kız fantom ovaryum ve rahim dozları 11.65 ve 10.25 mGy bulundu. 10 yaş grubunda erkek fantom testis ve prostat dozları 13.69 ve 10.80 mGy, kız fantom ovaryum ve rahim dozları 9.51 ve 8.50 mGy bulundu. 15 yaş grubunda erkek fantom beyin, kolon, karaciğer, mide, testis, tiroid, böbreküstü bezi, safra kesesi, böbrek, pankreas, prostat, ince barsak, spinal kord, dalak, timüs dozları 8.81, 8.51, 8.60, 8.22, 12.43, 12.76, 7.36, 7.44, 8.49, 6.88, 7.88, 9.84, 7.42, 8.48, 8.45, 8.56 mGy, kız fantom beyin, kolon, karaciğer, mide, ovaryum, tiroid, böbreküstü bezi, safra kesesi, böbrek, pankreas, rahim, ince barsak, spinal kord, dalak, timüs dozları 9.30, 10.45, 9.34, 9.41, 7.95, 14.66, 7.85, 8.33, 10.10, 8.39, 8.86, 6.88, 9.11, 9.03, 9.48, 9.32 mGy bulundu. Sonuç: 5 grupta total efektif doz değerinde cinsiyete bağlı bir farklılık görülmemiştir. 5 grupta erkek fantom testis dozu, kız fantom ovaryum dozuna göre yüksek bulunmuştur. Yeni doğan, 1, 5, 10 yaş kız ve erkek fantom organ dozlarında anlamlı bir farklılık bulunmazken 15 yaş grubunda doz dağılımları değişmiştir.
