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.

Stellarray提出开发一种新型的高强度版本的数字可寻址（像素化）X射线源（HI-DAXS），用于癌症成像应用。Stellarray的初步工作显示了反射模式、数字可寻址X射线源的基本可行性。拟议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-在实际的癌症成像系统中使用这些源。HI-DAXS的主要预期用途将是数字乳腺断层合成摄影、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），尽管这些源可以重新设计用于荧光透视、全身CT、数字X线摄影和其他模式。
