Outline of Final Research Achievements

Experimental study of high dose rate radiotherapy using flattening filter free (FFF) mode of linear accelerator measuring surface skin dose and dose within build-up area was performed. On the other hand, development of a new treatment planning system considering time factor was started using PHITS simulation algorithm.
In clinical application of high dose rate radiotherapy using flattening filter free (FFF) mode of linear accelerator, stereotactic body radiotherapy (SBRT)was applied for early stage lung cancer and liver cancer. Functional images of MRI using Gd-EOB-DTPA was also used for SBRT　of liver cancer. Intensity-modulated radiotherapy (IMRT) using high dose rate radiotherapy　 with flattening filter free (FFF) mode was applied for prostate and head & neck cancer.Volumetric multiple arc therapy (VMAT) was applied for esophageal cancer using high dose rate.
