| Abstract: | With the continuous development of image fusion technology in the field of medical imaging, more and more new imaging technologies and imaging devices have emerged. PET/CT combines PET and CT modal medical images to complement each other and improves the efficiency and accuracy of doctors'' diagnosis of diseases. Wavelet transform plays an important role in medical image fusion. The algorithm based on wavelet transform makes the details of the fused image clearer and easier to diagnose diseases. It has become the focus of research in the field of medical image fusion in recent years. The research progresses of PET/CT image fusion algorithm based on wavelet transform were reviewed in this article. |
