Abstract:

<p>Non-gated images (in the absence of external trigger) cannot reconstruct 3D volumes directly due to mismatch of acquisition intervals. Such a type of image needs synchronization for making direct reconstruction into 3D volume from 2D data set. Since, Spatio-temporal resolution is more important when dealing with reconstruction methods and noise reduction techniques, often wavelets are used. To reduce motion artifacts, wavelet denoising is performed. Wavelet correlation is performed on image sequences for synchronization. After correlating all image sequences, reconstruction will be performed to get 4D imaging. Comparison is made for different synchronization methods with and without wavelets by finding their root mean square error and peak signal-to-noise ratio (PSNR). ©2010 IEEE.</p>
