摘要

术中热成像的运动校正是一个巨大的挑战。运动和生理过程，如大脑活动引起的热传递，都表现在温度变化中。为了明确地检测和纠正运动，我们采用了共配准的可见光图像。补充我们之前的工作，我们提出了一个完整的工作流程，并通过分析运动校正前后的呼吸和脉冲频率来验证方法。我们的方法能够在不影响生理温度变化的情况下精确地纠正运动。

Motion Correction for Thermography using Co-registered Visual-Light Images

Motion correction for intraoperative thermography is a great challenge. Both motion and physiological processes, such as heat transfer due to brain activity, are manifested in temperature variations. To unambiguously detect and correct motion, we employ co-registered visual-light images. Complementing our previous work, we propose a complete workflow and verify the methods by analysing breath and pulse frequencies before and after motion correction. Our approach is able to accurately correct motion without affecting physiological temperature shifts.
