RDT(A45) is similar in principle tophotodynamic therapy (PDT) – a common treatment radiation oncologists use toshrink malignant tumors in cancer patients. During PDT, a patient takes aspecific drug and LASER light is directed at the tumor on, or near the surfaceof the skin.
A45治疗（RDT）原理上与光动力治疗（PDT）类似—放射肿瘤科医师用于缩小癌症病人的恶性肿瘤的一种普通疗法。光动力治疗期间，病人服用一种特定药物，在肿瘤或者在皮肤表面附近定向进行激光照射。

But Fox Chase will be testing RDT(A45)using a novel radiation machine called a LA45 RaceTrack Microtron in aclinical research setting. This machine generates high-energy photonswhich are used to activate a drug to attack deep-seated tumors located anywherein the body.
但是FCCC进行A45治疗(RDT)测试，在临床研究装置中使用一种与众不同的放射设备A45加速器，它能产生高能光子，这种光子能激发药物攻击在身体任何部位深度隐藏的肿瘤。

“This technology has been tested in cancerpatients in China.* The resultsinitiated our interest in bringing this treatment to patients in the UnitedStates," said Chang-MingCharlie Ma, PhD, Vice Chairman of the Departmentof Radiation Oncology and Director of Radiation Physics at Fox Chase CancerCenter.
“这种技术已经在中国癌症病人身上试过，使用结果激发了我们把该治疗方法引进到美国给病人使用的兴趣”，FCCC放射肿瘤科副主席，放射物理主任马长明CharlieMa博士说道。

Fox Chase will acquire this newtechnology through a research partnership with Top Grade Healthcare, a Chinesemedical supply company based in Beijing. This partnership will bring about anovel research program.
FCCC将从研究合作伙伴大基医疗（总部位于北京的中国医疗设备公司）获得这项技术，此项合作将带来新的研究项目。

Ma said this project includes threeradiation machines provided by Top Grade, including the Microtron toconduct the research.
Charlie Ma说该项目包括三台由大基医疗提供的放射设备，其中包括实施研究的电子加速器。

“It’s a treatment that does not exist anywherein the U.S.,” Horwitz said. “So it’s truly exciting.”
“这是一种无论在美国哪都没有的治疗方法”Horwitz说“但是它却真实存在。”

*The treatment wastested at Wuxi Yiren Hospital, one of the Top Grade group ofcompanies. Fox Chase has an affiliation with Wuxi Yiren.
该疗法已在大基医疗集团旗下的无锡亿仁医院通过测试。FCCC已在无锡亿仁医院设立分院。
