In the development of a magnetic resonance imaging spectrometer, the equipment fault detection methods are mainly reliant on visual inspection of reconstructed images or k‐space data, combined with observation of the output waveforms via an oscilloscope. However, when using the above methods, it may be quite difficult to determine minor design flaws that would produce image ghost or other problems...
The non-local means algorithm has been proven to allow a good image restoration performance of MR images. However, this method utilizes all pixels of the images, some of which might be useless for noise removal. In this paper, an improved pixel-selection-based non-local means algorithm which avoids the usage of useless pixels is supplied. The principle of pixel selection is based on the similarity...
