OBJECTIVE
To develop a new method of PET and CT cross-modality medical image fusion based on out-location frame.
METHODS
PET/CT cross-modality medical images were obtained based on the out-location frame and the external fiducial marker on the frame was used for rigid medical image registration. A variation model based on the wavelet transform was used for image fusion.
RESULTS
The CT images were displayed by grey scale and overlaid with the PET images displayed by chromatic scale to obtain the image after registration and fusion.
CONCLUSION
The method of external markers registration can be effective and accurate in achieving PET and CT image fusion.
目的
开发一种基于外置框架的PET与CT跨模态医学图像融合新方法。
方法
基于外置框架获取PET/CT跨模态医学图像，并使用框架上的外部基准标记进行医学图像刚性配准。采用基于小波变换的变分模型进行图像融合。
结果
CT图像以灰度显示，并与以彩色显示的PET图像叠加，得到配准融合后的图像。
结论
外部标记配准方法在实现PET与CT图像融合方面可有效且准确。
