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.
