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

所有患者都接受了2100IX醫療直線加速器的治療，這是由Varian醫療系統公司(Palo Alto, CA, USA)研制開發的，現在可以在治療之前使用車載影像檢查設備進行檢查并調節定位。影像檢查設備幫助臨床醫生在治療過程中，對目標腫瘤進行觀察和定位。

新西蘭南島Christchurch醫院放射治療臨床經理Viv All評論說：“這些影像為我們增加劑量提供了信心，特別是前列腺癌患者，這已經通過臨床試驗證實了對患者的效益。我們沒有很多機會來更換設備，因此我們決定站出來提供現代放射治療技術。我們覺得影像介導的放射治療[IGRT]和呼吸門控系統正是我們想提供給患者的產品。”

ChristChurch醫院使用Varian公司的RPM呼吸門控系統和GE健康保健公司的(Waukesha, WI, USA)CT掃描儀來監測調節由呼吸導致的腫瘤運動。

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.
