The use of the latest technology in radiation therapy for prostate cancer treatment by (VMAT-SIB
and IMRT-SIB) methods is conducted with using 3D in treatment planning. The purpose of this
study is to calculation done the total radiation doses by linear quadratic model (LQ). Mainly, the
study objective is to a comparative analysis of methods of irradiation of prostate cancer. Use highly
radiation doses for prostate cancer treatment while keeping normal cells (rectum, bladder, left femur,
right femur, and bones) safe from highly radiation doses. The study of seven prostate cancer patients
was conducted. The first patient had done prostate cancer treatment in two sessions by VMAT-SIB
and IMRT-SIB methods and use a 9-field sliding window IMRT technique. The second patient had
done prostate cancer treatment in three sessions by VMAT-SIB and IMRT-SIB methods and use a 4-
field sliding window IMRT technique. Calculation of radiation doses was carried out for four
patients. We done radiation treatment planning work to the patient with prostate cancer by 3D
technique and using (VMAT-SIB and IMRT-SIB) methods. Total radiation doses (48.000GY).
Calculate was done total radiation doses (minimum dose, maximum dose, mean dose, and other
doses) for each normal tissues are (rectum, bladder, left femur, right femur, and bones) in stage the
prostate cancer prostate treatment. The VMAT-SIB and IMRT-SIB) methods are more effective
treatment, increased higher total radiation doses, shorter total treatment time, and at the same time
had low side effects on normal tissues.
