Please help me translate the following Chinese into English and make the introduction professional为实现患者医学图像与世界空间下的患者配准本研究将单目相机坐标系定义为世界坐标系并将医学图像坐标系和患者坐标系都统一在此。本研究采用的个性化标记物与患者在术中刚性固定将标记物坐标系与患者坐标系视为一体进行注

In order to achieve patient medical image registration with the world space, this study defines the monocular camera coordinate system as the world coordinate system and unifies the medical image coordinate system and patient coordinate system in it. Personalized markers are used in this study and rigidly fixed to the patient during surgery. The marker coordinate system and patient coordinate system are registered as a whole. As medical images are obtained from patients' scans, this study completes the registration of two coordinate systems based on the characteristic that patients and markers exist in both the real world and image space. The registration process of medical image-patient space is shown in Figure 1
