THE PURPOSE OF THE CONTRACT IS TO DEVELOP A NOVEL, HIGH-INTENSITY VERSION OF A D

Stellarray提议开发一种新型的高强度数字可寻址（像素化）x射线源（HI-DAXS），用于癌症成像应用。Stellarray的初步工作已经显示了一种反射模式、数字寻址x射线源的基本可行性。该项目的总体目标是解决关键问题——阴极阵列的高电流密度像素和在阳极提供必要的热管理能力的架构创新——以便在实际的癌症成像系统中使用这些源。HI-DAXS的主要用途将是数字乳房断层合成、小动物CT和血管生成成像系统（Stellarray正在与大学合作伙伴进行系统开发工作），尽管来源可以重新设计用于透视、全身CT、数字x线摄影和其他模式。

Stellarray proposes to develop a novel, high-intensity version of its digitally-addressable (pixilated) x-ray source (HI-DAXS) for use in cancer imaging applications. Preliminary work at Stellarray has shown the basic feasibility of a reflective-mode, digitally-addressable x-ray source. The overall goal of the proposed project is to address the key issues - high current density pixels for the cathode arrays and architectural innovations to provide the necessary thermal management capability at the anode - for using these sources in practical cancer imaging systems. The primary intended uses of the HI-DAXS will be in digital breast tomosynthesis, small animal CT and angiogenesis imaging systems (where Stellarray has system development work under way with university partners), although the sources can be re-designed for fluoroscopy, full-body CT, digital radiography and other modalities.
