Young patients suffering from Cooley's anemia experience a life threatening accumulation of iron, particularly in the heart and liver. Effective removal of deposited iron by chelating drugs requires a timely and accurate assessment of iron level in the patient. There is an urgent need for development of a rapid, inexpensive and safe method to determine the iron concentration in the organ tissues of Cooley's anemia patients. This proposed contract address the development of an innovative probe for in-situ, real-time detection of iron deposits, as well as levels of certain other trace elements. The technology is based upon a x-ray fluorescence system assembled at the tip of a minimally-invasive 3.2 mm diameter probe. The probe can be introduced in place of a biopsy needle, either laparoscopically or through various anatomical passageways. It is designed to make intimate contact with heart, liver, and other organ tissues to take a direct reading of trace element content. The innovation introduced is a significant improvement over existing technology and for the first time, allows the detection of trace elements in body tissues at the patient's bedside.

患有库利氏贫血症的年轻患者经历了 威胁铁的积累，特别是在心脏和肝脏。 螯合药物有效去除沉积铁需要及时 并准确评估患者体内的铁水平。目前迫切 需要开发一种快速、廉价且安全的方法来确定 库利氏贫血患者器官组织中的铁浓度。 该合同旨在开发一种创新的探头， 现场实时检测铁沉积物，以及 其他微量元素。这项技术是基于X射线 荧光系统组装在微创3.2 mm 直径探头。探针可以代替活组织检查针引入， 或者通过腹腔镜或者通过各种解剖通道。是 旨在与心脏、肝脏和其他器官进行亲密接触 直接阅读微量元素含量。创新 这是对现有技术的重大改进， 第一次，允许检测人体组织中的微量元素， 病人的床边。
