가톨릭대/Christopher F. Njeh, 서태석*
It is premature to replace physical wedges by other techniques completely, even though there are no technical issues in realizing advanced radiotherapy technologies. Although the recent trend of radiation treatments in developed countries shows a rapid decrease in hard wedge utilization, the speed of catching up with necessary infrastructure in underdeveloped countries is not as fast as desired, leaving them no choice but to continue to use hard wedges in many cases. Thus, I believe that it is not yet the time to completely eliminate the use of hard wedges.
