港安健康分析Unity MR linac精准放疗优势 目前,大多数放射治疗系统是利用锥束计算机断层扫描(CBCT),虽然这些系统能很好地显示骨质解剖结构,但其软组织的特征却很差,且无法实时成像,这让放疗对脂肪肉瘤等软组织肉瘤无法达到最佳效果。香港看病服务机构港安健康国际医疗介绍,磁共振导航放射治疗机Unity MR Linac的出现,打破...
MagnetTx Oncology Solutions Ltd. designs, manufactures and markets the MagnetTx Aurora-RT. Aurora-RT is a cancer treatment system that combines high-quality MRI and simultaneous linear accelerator-based radiation therapy treatment (MR-LINAC).
治疗计划在定位CT上用Monaco系统计算(参考计划),MR加速器(1.5 T Unity MR-Linac, Elekta, AB, Stockholm, Sweden)支持野静态调强(step&shoot IMRT),采用无均整器(flattening filter free,FFF)模式、7 MV X线照射,将1.5 T磁场的影响纳入计算。 治疗实施当日参考体...

for the certified low field MR-linac, adaptation of the table position (3D translation) or full re-optimization are feasible, whereas for the certified high field MR-linac, no table correction is feasible, but the plan has to be adapted instead. Besides full re-optimization of the plan, whi...

Purpose/Objective(s) The MR-Linac (MRL) provides a platform for adaptive stereotactic body radiation therapy (SBRT). This study aims to 1) compare liver tumor volumes on multiphasic liver CT and MR simulation imaging to tumor volumes on MRL images and 2) measure changes in liver tumor volume...
Cobalt systems are currently on the market and soon the first clinical MR-linac based on a 7 MV linear accelerator and a 1.5T MRI scanner will become operational.It is a misconception to consider the MR-guided radiotherapy systems as the next generation CBCT-linacs. The combination of a ...
