Cone Beam CT research under way

NCC Korea is helping advance the use of Cone Beam computed tomography (CT) to help more precisely position the proton beam for optimal effectiveness.

“Cone Beam CT will allow us to have 3-D patient imaging so we can calculate the proton beam very accurately,” says Se Byeong Lee, Ph.D., chief medical physicist, National Cancer Center of Korea (NCC).

The benefits of 3-D imaging include more detailed information on beam alignment, the ability to respond to patient anatomical changes and the ability to re-plan beam arrangements. Currently, NCC is using 2-D X-ray technology to determine patient setup prior to proton treatment.

“With 3-D imaging, we can position the patient very accurately,” says Lee. “We have developed a basic concept and a basic algorithm for a Cone Beam CT system.”
