Image fusion in medical ultrasonic imaging

Image fusion is fundamental problem in image analysis and processing, and is used widely in medical imaging. To acquire better medical ultrasonic image of diagnosis, image fusion is introduced in ultrasonic imaging. The harmonic image and fundamental image are decomposed into sub-images with wavelet transform. Fusion is completed with rules based on windows. Then fusion image is reconstructed. Results show the fusion image is better, and computation results show the signal to noise is higher. So the fusion method makes the diagnosis of illness more accurate.
