Signal denoising in MR tomography using wavelet
Original language description
The wavelet transformation is the modern method for signal processing in many technical branches. One of them is the removal of noise from a useful signal. This article is focused on removing noise from the signal scanned in a nuclear magnetic resonancetomograph. The method of sub-band thresholding utilizing wavelet transformation is analysed. This method is applied in dual filtering of Free Induction Decay (FID) signal and Instantaneous Frequency (IF) signal. Marked noise suppression is reached, a higgher quality of instantaneous frequency signal is obtained and so the magnetic field in tomograph can be measured to a greater accuracy.
