Abstract

Objective: Cadaver's sectioned images with high resolution and real color could be used as the source of realistic three-dimensional images. If the sectioned images are registered to a patient's MRIs, three-dimensional images with high resolution and real color that fit the patient, can be produced; the three-dimensional images enable realistic virtual surgery for the patient. The objective of this study was to verify the registration of a cadaver's sectioned images to a patient's head MRIs. Methods: The sectioned images of the heads of cadaver were associated with segmented images selected at 3 mm intervals. The patient had his head MR scanned at 3 mm intervals; the MRIs were segmented. Software to register the cadaver's sectioned images to the patient's MRIs was developed. On this software, the corresponding dots were identified on both the sectioned images and the MRIs either manually or automatically using segmented images. Results: The registered sectioned images corresponded to the patient's MRIs. Both manual and automatic registrations were satisfied. Conclusion: Further study is needed for registering sectioned images to actual patients.

尸体切片图像与患者头部核磁共振成像的配准

目的:利用高分辨率、真实色彩的尸体切片图像作为逼真的三维图像来源。如果将切片图像与患者的核磁共振成像相匹配，就可以产生适合患者的高分辨率和真实颜色的三维图像;三维图像使患者能够进行真实的虚拟手术。本研究的目的是验证尸体切片图像与患者头部核磁共振成像的注册。方法:将尸体头部的切片图像与间隔3 mm的分割图像相关联。患者每隔3毫米进行一次头部磁共振扫描;mri被分割。开发了将尸体切片图像与患者的核磁共振成像相匹配的软件。在该软件上，通过手动或自动分割图像，在切片图像和核磁共振成像上识别相应的点。结果:配准的切片图像与患者的mri相符。手动和自动注册都得到了满足。结论:切片图像与实际患者的配准有待进一步研究。
