Medical Image of PET/CT Weighted Fusion Based on Wavelet Transform

Image fusion as a kind of information-integrated technology has been used in many fields recently. For medical images, the medical machine of PET/CT makes the within-machine fusion come true. Although the fusion image not only has the character of CT that can make a precise location of pathological changes but also has the character of PET that can detect the pathological as early as possible. As the within-machine fusion equipments are very expensive, it leads a high fee. Only some large hospitals are equipped with the within-machine fusion equipment. So a large space has been left to the development of fusion differences. Based on the wavelet-transform, the fusion of the CT image and PET image comes true. In the end, we gain the fusion CT/PET image. We can detect and locate the pathological changes exactly and immediately in the fusion image. And actually, this is the predominance of the fusion image.
