| Research Abstract |
The description of low density material reconstructed by mega voltage image doesn' t reach kilo voltage one because the flattening filter of linear accelerator causes beam hardening and an increase of scattered photon. To solve this problem reasonable, we designed a new portal device used the electron beam mode of linear accelerator. This device is attached on the shadow tray of the accelerator, has a target consist of low atomic number material, and outputs bremsstrahlung X-ray by electron beam.
