The development of a whole-scalp, high sampling-density diffuse optical tomography (DOT) system is a critical next step in the evolution of the field of diffuse optics. To achieve this with optical fiber bundles is extremely challenging, simply because of the sheer number of bundles required, and the associated challenges of weight and ergonomics. Dispensing with optical fiber bundles and moving to head-mounted optoelectronics can potentially facilitate the advent of a new generation of wearable, whole-scalp technologies that will open up a range of new experimental and clinical applications for diffuse optical measurements. Here, we present a concise review of the significant progress that has been made toward achieving a wearable, fiberless, high-density, whole-scalp DOT system. We identify the key limitations of current technologies and discuss the possible opportunities for future development.
开发全头皮、高采样密度的扩散光学断层扫描(DOT)系统是扩散光学领域发展的关键下一步。要通过光纤束实现这一点极具挑战性,仅仅是因为所需光纤束数量庞大,以及与之相关的重量和人体工程学方面的挑战。摒弃光纤束并转向头戴式光电子设备可能会推动新一代可穿戴全头皮技术的出现,这将为扩散光学测量开启一系列新的实验和临床应用。在此,我们简要回顾在实现可穿戴、无光纤、高密度全头皮DOT系统方面所取得的重大进展。我们确定了当前技术的关键局限性,并讨论了未来发展的可能机遇。
