Popis:	Introduction. Study performed to evaluate repeatability and effectiveness of the static-junctions image guided (SJIG) method of craniospinal irradiation. Material and methods. The analysis of 40 treatment plans was performed. All treatment plans were reviewed with regard to the distances between isocentres between every single field of each fraction during all the treatment days. Based on that data, second (actually treated) plans were created. The planned and treated parameters were compared. Results. The study group consisted of 40 patients irradiated on the craniospinal region. Data on 902 fractions and 1635 isocentres positions was collected. One-, 2- and 5-year overall survival was 95%, 89% and 78%, respectively. Spine metastases were observed in the regions which were covered with homogenous dose during the treatment. Conclusions. SJIG is safe and produces very good long-term outcome. Treatment planning and delivery is simple with good reproduction of the planned dose distribution during the actual treatment.
