tailieunhanh - Stereotactic ablative body radiotherapy with a central high dose using CyberKnife for metastatic lung tumors

The CyberKnife system features a robotically-positioned linear accelerator to deliver real-time imageguided stereotactic ablative body radiotherapy (SABR). It achieves steep dose gradients using irradiation from hundreds of different directions and increases the central dose of the gross tumor volume (GTV) without increasing the marginal dose to the planning target volume. |
