[Development of a system to assist patient positioning in radiation therapy].
We have developed a system to assist in patient positioning for radiation therapy that includes an automated registration process between the reference image and target volume data before irradiation. The system uses the cross-correlation function between images for the automatic positioning processing algorithm. Evaluation of the system showed good results in providing highly accurate registration. Therefore, the system is suitable for use in clinical study. In addition, evaluation of clinical data of the prostate using the system revealed displacement of the internal organs.
