近日,广州泰和肿瘤医院放疗科利用直线加速器成功开展首例脑转移瘤立体定向放射治疗(stereotactic radiation therapy, SRT)。 什么是立体定向放射治疗 立体定向放射治疗是指利用定向技术,使用小野集束射线对靶区施以较大剂量的分次照射。该技术有利于患者正常组织的保护及肿瘤组织照射剂量的提高,可对肿瘤乏氧细胞进行高剂量杀...
在医学领域,'Stereotactic'技术被广泛应用于放射治疗、神经外科手术以及其他需要高精度定位的治疗中。立体定向放射治疗(Stereotactic Radiotherapy, SRT)是一种高精度、高剂量的放射治疗技术,主要用于治疗脑部、脊柱和其他部位的小肿瘤或病变。它利用CT、MRI和PET等先进成像技术,达到毫米级别的定位精...

Stereotactic Radiation Therapy (SRT) is a cancer treatment. This type of external radiation therapy uses special equipment to precisely deliver radiation
Between April 1999 and December 2005, 59 patients with T1-2N0M0 lung cancer were treated by stereotactic radiation therapy (SRT). The 2-year local control and overall survival rates according to stage were 100%, 75% with Stage IA disease and 91%, 71% with Stage IB disease. Main cause ...
SRT allows for the delivery of a very high dose of radiation to a precise target. SRT presents the challenge of organ motion throughout the respiratory cycle. We review methods to mitigate this problem using both frame-based and frameless techniques, implanted fiducial markers, respiratory gating ...
Stereotactic radiosurgery (SRS) and stereotactic radiation therapy (SRT) for neurooncological and neurological diseases: state of the art and future perspe... Stereotactic radiosurgery (SRS) and fractionated stereotactic radiotherapy (SRT) are well established in a high number of neurooncological and ...
1.Stereotactic Body Radiation Therapy (SBRT)is a general term of radiation therapy,which applies stereotactic technique and special ray generating equipment that focuses high energy rays of multi-source,multi-beam,or multi-field on a target,obtaining high curative but low side effect,because of high...
In this study, an MR-based radiomics framework was proposed to derive and investigate quantitative MRI (qMRI) biomarkers for the outcome of LF in brain metastasis patients treated with hypo-fractionated stereotactic radiation therapy (SRT). The qMRI biomarkers were constructed through a multi-step ...
PURPOSE: Stereotactic radiotherapy (SRT) combines techniques of stereotactic radiosurgery (SRS) with radiation therapy fractionation schemes. Fractionation... HM Kooy,SF Dunbar,NJ Tarbell,... - 《Int J Radiat Oncol Biol Phys》 被引量: 409发表: 1994年 A problem in rotation therapy with X Rays ...
