Wireless x-ray dosimeter for blood sterilization

绝大多数涉及输血的医疗程序需要对血液进行X射线灭菌，以避免患者感染或过度免疫反应。目前的血液消毒系统依赖于人类操作者对放置在每个血袋上的“rad标签”的颜色变化的评估，以便确定施加了足够的辐射，因此血液被适当地消毒。这些系统效率低下，容易出错，导致血液浪费和成本增加。 Carleton开创了许多Si MOSFET/CMOS剂量计和无线IC技术，这些技术可以用嵌入RFID的无线剂量计取代rad标签。最近，渥太华地区的一家公司Best Medical已经认识到CMOS IC技术在几个方面增强其血液灭菌器的潜力，特别是通过消除rad标签和实现整个灭菌过程的自动化。拟议的工作是证明硅CMOS无线X射线剂量计组件的概念，用于血液消毒，以满足最佳的未来需求。目标是开发剂量计设备，将被Best纳入其血液辐照器产品的增强版本，在全球大市场中提供显着的竞争优势。

The vast majority of medical procedures involving blood transfusions require x-ray sterilization of the blood to avoid patient infection or excessive immune response. Present-day blood sterilization systems rely on a human operator's assessment of the color change of "rad tags" placed on each blood bag, in order to ascertain that sufficient radiation was applied and hence that the blood was properly sterilized. These systems are inefficient and prone to error, resulting in wasted blood and increased costs. Carleton has pioneered a number of Si MOSFET/CMOS dosimeter and wireless IC technologies that could allow the replacement of rad tags by wireless dosimeters having embedded RFID. Recently, an Ottawa-area company, Best Medical, has recognized the potential of CMOS IC technology for enhancing their blood sterilizers in several ways, notably through the elimination of rad tags and the automation of the complete sterilization procedure. The proposed work is to prove the concept of Si CMOS wireless x-ray dosimeter components for blood sterilization to meet the Best's future needs. The goal is to develop dosimeter devices that would be incorporated by Best into enhanced versions of their blood irradiator products, providing significant competitive advantage in a large world-wide market.
