| 目的 研制一种图像体外标记物，用于核素功能性图像与解剖结构性图像（CT、MRI等）异机配准融合，以提高异机图像融合精度。方法 设计加工一种特殊的塑料小球壳（标记球），将球壳内装满核素显像液用于受检者靶区体外显像标记。将同等大小的标记球内分别装入CT和MR对比剂或CT/MR双模态显影液，行CT和MR扫描后观察图像融合效果。结果 标记球在核素图像上的浓集点清晰，大小适中，图像标记明显。标记球亦可用于CT/MR的图像融合。结论 图像体外标记物可用于图像配准融合，临床应用效果满意。 |

| Objective To explore an external marker for registered image fusion of functional radionuclide image and anatomical CT and/or MR image for improving precision of image fusion. Methods A marker with special plastic shell filling up with radionuclide liquid was designed and used in radionuclide imaging. The result of image fusion of CT and MR images by using this external marker filled up with CT/MR bimodal contrast agent was observed. Results The marker had moderate size and was clearly visible with high radioactivity concentration. It was also suitable for CT/MR image fusion. Conclusion The external marker can be used in imaging fusion,and has satisfied clinical effects. |
