一種新型直線加速器配備了車載影像設(shè)備，幫助新西蘭人獲取了劃時(shí)代的影像引導(dǎo)放射治療（IGRT），將精確性進(jìn)行了最佳化處理，確保臨床醫(yī)生改善了患者的臨床預(yù)后。

所有患者都接受了2100IX醫(yī)療直線加速器的治療，這是由Varian醫(yī)療系統(tǒng)公司(Palo Alto, CA, USA)研制開發(fā)的，現(xiàn)在可以在治療之前使用車載影像檢查設(shè)備進(jìn)行檢查并調(diào)節(jié)定位。影像檢查設(shè)備幫助臨床醫(yī)生在治療過程中，對(duì)目標(biāo)腫瘤進(jìn)行觀察和定位。

新西蘭南島Christchurch醫(yī)院放射治療臨床經(jīng)理Viv All評(píng)論說：“這些影像為我們?cè)黾觿┝刻峁┝诵判模貏e是前列腺癌患者，這已經(jīng)通過臨床試驗(yàn)證實(shí)了對(duì)患者的效益。我們沒有很多機(jī)會(huì)來更換設(shè)備，因此我們決定站出來提供現(xiàn)代放射治療技術(shù)。我們覺得影像介導(dǎo)的放射治療[IGRT]和呼吸門控系統(tǒng)正是我們想提供給患者的產(chǎn)品。”

ChristChurch醫(yī)院使用Varian公司的RPM呼吸門控系統(tǒng)和GE健康保健公司的(Waukesha, WI, USA)CT掃描儀來監(jiān)測(cè)調(diào)節(jié)由呼吸導(dǎo)致的腫瘤運(yùn)動(dòng)。

Liner Accelerator Imaging Device
 
A new linear accelerator with an on-board imaging device has given people in New Zealand access to cutting-edge image-guided radiation therapy (IGRT) that optimizes accuracy and enables clinicians to potentially improve patient outcomes.

All patients treated with the 2100IX medical linear accelerator, developed by Varian Medical Systems (Palo Alto, CA, USA), are now imaged with the On-Board Imager device to check and adjust positioning before treatment. The imager enables clinicians to see and target tumors more accurately during treatment sessions.

“The images give us the confidence to increase doses, particularly for our prostate cancer patients, which has been shown through clinical trials to be beneficial for the patient,” remarked Viv All, radiation therapy clinical manager, Christchurch Hospital, South Island, New Zealand. “We don’t get many opportunities to replace equipment and we decided we wanted something that would make us stand out and was in the forefront of modern radiotherapy technology. We felt that image-guided radiation therapy [IGRT] and respiratory gating were that we wanted to offer our patients.”

ChristChurch Hospital uses Varian’s RPM respiratory gating system in conjunction with a GE Healthcare’s (Waukesha, WI, USA) computed tomography (CT) scanner to monitor and adjust for tumor motion caused by breathing.
