TomoTherapy system Conventional Linacs VS. TomoTherapy system Continuous Rotation Fast Binary MLC + MLC designed for IMRT 10 times less transmission and leakage then conventional MLCs; 10 times faster MLC Speed = Helical Delivery + Tens of thousands of beamlets produced in standard treatment times Slip-ring gantry designed for IGIMRT. Continuous rotation with variable speeds (15 - 60 seconds) • 기존에 시행해왔던 선형가속기를 기반으 로 한 세기조절방사선치료보다 더욱 정밀 하여 치료 오차를 획기적으로 감소시킨 장 비이다. 기존 방사선 암치료 장비의 장점 만을 하나로 집약한 암치료기라서 꿈의 암 치료기라 불리우며 현존하는 방사선 치료 기 중 최첨단 장비라 할 수 있다.
