A Novel In-Vivo Cell Tracking System Based on Combined XCT and FT

描述（由申请人提供）：我们建议建立世界上第一个组合的X射线计算机断层扫描（XCT）和荧光断层扫描（FT）系统。该系统的构建将为从事干细胞和癌症研究的研究人员创造一种新的分子成像工具。干细胞研究为开发用于治疗疾病的细胞疗法带来了巨大的希望，因此细胞追踪方法的开发是极其重要的。DxRay Inc.的研究人员团队开发的几项重要科技创新。（Northridge，CA）和加州尔湾大学（UCI）允许创建新颖的组合XCT和FT系统。该项目产生了一种独特的双模态成像方法，结合了功能和解剖信息，并提供了一种新的分子成像方法。在拟议项目完成后，XCT和FT系统的组合将为UCI的动物成像设施增加独特的成像能力。此外，DxRay开发的创新XCT技术和UCI开发的新型FT技术将在Gamma Medica Ideas（Northridge，CA）的支持下实现商业化，Gamma Medica Ideas对此开发非常感兴趣，并为组合系统提供机架。细胞疗法显示出治疗许多疾病的巨大前景，但不幸的是，很少有非侵入性技术存在于给药后跟踪细胞。非侵入性地监测体内纵向细胞运输的能力是新兴细胞治疗策略的迫切需要，因为这可用于评估反应。细胞的体内追踪在涵盖神经病学、肿瘤学和心脏病学领域的各种疾病中具有广泛的潜在应用。因此，为了满足对新的多模态分子成像技术的需求，该技术能够对小鼠进行非侵入性体内纵向成像以进行细胞跟踪，我们建议建立第一个此类组合XCT和FT系统。这项非常有前途的新技术的发展，第一个将联合收割机FT与XCT的解剖信息结合在一个相对便宜且易于使用的系统中，将为干细胞研究和靶向药物递送研究创造一个强大的新工具。我们正在开发一种新型的体内结合X射线计算机断层扫描（XCT）和荧光断层扫描（FT）系统。这项新技术将创造一种新型的双模态分子成像。该项目将创造新的细胞跟踪能力，并将有利于细胞疗法的临床前研究。

DESCRIPTION (provided by applicant): We propose to build the world's first combined x-ray computed tomography (XCT) and fluorescence tomography (FT) system. The construction of this system will create a new molecular imaging tool for researchers performing stem cell and cancer research. Stem cell research holds great promise for the development of cellular therapies for the treatment of disease and the development of cell tracking methods is therefore extremely significant. Several important scientific and technological innovations developed by our team of investigators at DxRay Inc. (Northridge, CA) and the University of California Irvine (UCI) allow the creation of a novel combined XCT and FT system. This project produces a unique dual-modality imaging methodology that combines functional and anatomical information and provides a new approach to molecular imaging. At the completion of the proposed project the combined XCT and FT system will add unique imaging capabilities to the animal imaging facilities at UCI. Furthermore, the innovative XCT technology developed by DxRay and the novel FT technology developed by UCI will be commercialized with support from Gamma Medica Ideas (Northridge, CA) who are very interested in this development and are providing a gantry for the combined system. Cellular therapeutics show great promise for the treatment of many diseases, but unfortunately few non-invasive techniques exist for tracking the cells after administration. The ability to non-invasively monitor cell trafficking in-vivo longitudinally is a pressing need for emerging cellular therapeutic strategies since this could be used to assess response. In-vivo tracking of cells has a broad range of potential applications in various diseases covering the fields of neurology, oncology, and cardiology. Therefore, to address the need for new multi-modality molecular imaging technologies, that are capable of the non-invasive in-vivo longitudinal imaging of mice for cell tracking, we propose to build the first of its kind combined XCT and FT system. The development of this very promising new technology, the first to combine FT with anatomical information from XCT in a relatively inexpensive and easy to use system, will create a powerful new tool for stem cell research and targeted drug delivery studies. We are developing novel in-vivo combined x-ray computed tomography (XCT) and fluorescence tomography (FT) system. This new technology will create a new type of dual-modality molecular imaging. This project will create new cell tracking capabilities and will benefit preclinical studies of cellular therapies.
