Fusion Based MR Images Denoising Technique Using Frequency Domain and Non-Local Means Filters

Autor: Christian Rudahunga, Henry Kiragu, Mary Ahuna

Publikováno v: WSEAS TRANSACTIONS ON SIGNAL PROCESSING. 18:153-163

The non-invasive and non-ionizing properties of Magnetic Resonance Imaging (MRI) in addition to the associated good image quality as well as high resolution make MRI more attractive than many other medical imaging techniques. However, during the acqu

An Efficacious MRI Sparse Recovery Method Based on Differential Under-Sampling and k-Space Interpolation

Autor: Henry Kiragu, Elijah Mwangi, George Kamucha

Publikováno v: 2020 IEEE 20th Mediterranean Electrotechnical Conference ( MELECON).

A proposed method that reduces the lengthy scan time characterizing Magnetic Resonance Imaging (MRI) is presented in this paper. The method also improves the robustness to noise and reconstruction artifacts associated with conventional MRI. It employ

A Robust Compressive Sampling Method for MR Images Based on Partial Scanning and Apodization

Autor: Elijah Mwangi, Henry Kiragu, George Kamucha

Publikováno v: ISSPIT

This paper proposes a robust, fast Magnetic Resonance Imaging (MRI) reconstruction algorithm. The method is based on Compressive Sampling (CS), profile of the k-space coefficients and sparsity in the wavelet transform domain. It commences with partia

A rapid MRI reconstruction method based on compressive sampling and concomitant artifacts suppression

Autor: George Kamucha, Henry Kiragu, Elijah Mwangi

Publikováno v: 2018 19th IEEE Mediterranean Electrotechnical Conference (MELECON).

In this paper, a proposed rapid Magnetic Resonance Imaging (MRI) reconstruction method is presented. The method is based on the compressibility of the images in the wavelet domain and suppression of the resulting artifacts. The proposed method commen

A hybrid MRI method based on denoised compressive sampling and detection of dominant coefficients

Autor: Elijah Mwangi, George Kamucha, Henry Kiragu

Publikováno v: DSP

In this paper, a hybrid method for acquisition and reconstruction of sparse magnetic resonance images is presented. The method uses conventional spin echo Magnetic Resonance Imaging (MRI) with only a few Phase-encoding steps to obtain the dominant k-

An Improved Reconstruction Method for Compressively Sampled Magnetic Resonance Images Using Adaptive Gaussian Denoising

Autor: Henry Kiragu, Elijah Mwangi, George Kamucha

Publikováno v: Emerging Trends in Electrical, Electronic and Communications Engineering ISBN: 9783319521701

In this paper, an improved Compressively Sampled Magnetic Resonance Imaging (CS-MRI) method that suppresses reconstruction noisy artifacts is proposed. The algorithm involves random undersampling of the k-space data of an MR image followed by reconst
