ACTIVE ENERGY SELECTIVE CASSETTE

双能量成像有可能增加新的和强大的诊断 医疗X光检查的能力。 不像普通的X光 图像，双能量图像数据可以被处理以给出关于 身体组织的化学成分。 这些新信息可以 例如，用于增强微钙化的可检测性， 乳房X光检查或胸部X光检查中的钙定量。 两者都是 重要的诊断指标。 在过去，需要专门的设备来生产双能源 图像. 采用计算机X线摄影系统， 普通放射学提供了所提出的工作所解决的机会。 长期目标是开发一种能量选择性盒式磁带， 与通用计算兼容的双能量数据 射线照相系统。 卡匣将使用一种独特的方法，该方法基于对 由Aprend Technology发明的发光增益。 这种新方法 产生比替代品高得多的质量双能量数据。 同时保持与通用设备的兼容性。 第一阶段的工作将表明这一方法的可行性。 如果第一阶段是 如果成功，第二阶段将建立一个原型，并在临床上进行测试。

Dual energy imaging has the potential to add new and powerful diagnostic capabilities to a medical X-ray examination. Unlike an ordinary X-ray image, dual energy image data can be processed to give information about the chemical composition of body tissues. This new information can be used, for example, to enhance the detectability of microcalcifications in mammography or to quantify calcium in chest radiography. Both are important diagnostic indications. In the past, specialized equipment was needed to produce dual energy images. The introduction of computed radiography systems for use in general radiology provides the opportunity addressed by the proposed work. The long-term goal is to develop an energy selective cassette to acquire dual energy data that is compatible with the general purpose computed radiography systems. The cassette will use a unique approach based on active modulation of luminescence gain invented by Aprend Technology. This new approach produces substantially higher quality dual energy data than alternative approaches while maintaining compatibility with general purpose equipment. The Phase I work will show the feasibility of the approach. If Phase I is successful, Phase II will build a prototype and test it clinically.
