Sažetak
Patients with cervical, uterine and rectum carcinomas are usually treated in the prone position using the bellyboard positioning device. Specific and uncomfortable prone position gives rise to the uncertainties in the daily set-up of the patients during the treatment. During the investigation of translational movements, rotational movements of the pelvis are observed and investigated. The film portal imaging is used in order to find patient positioning errors during the treatment. We defined the rotational set-up errors by angle deviations of the sacrum. Thirty six patients were included in the study ; 15 patients were followed during the whole treatment and 21 during the first 5 consecutive treatment days. The image acquisition was completed in 84%. Systematic and random positioning errors were analyzed in 725 images. Approximately half of the patients had adjusted to the bellyboard in the first few fractions, with sacrum angles remaining the same for the rest of the treatment. The other half had drifts of the sacrum angle during the whole treatment. The rotation of the patients’ sacrum during the treatment ranged up to 14o causing the usual set-up verification and correction procedure to result in errors up to 15 mm. Rotational movements of the patient pelvis during bellyboard pelvis radiotherapy can introduce considerable patient position error.
