Abstract
Background: Magnetic Resonance Imaging (MRI) plays an important role in the field
of medical diagnostic imaging as it poses non-invasive acquisition and high soft-tissue contrast.
However, a huge time is needed for the MRI scanning process that results in motion artifacts, degrades
image quality, misinterprets the data, and may cause discomfort to the patient. Thus, the
main goal of MRI research is to accelerate data acquisition processing without affecting the quality
of the image.
Introduction: This paper presents a survey based on distinct conventional MRI reconstruction
methodologies. In addition, a novel MRI reconstruction strategy is proposed based on weighted
Compressive Sensing (CS), Penalty-aided minimization function, and Meta-heuristic optimization
technique.
Methods: An illustrative analysis is done concerning adapted methods, datasets used, execution
tools, performance measures, and values of evaluation metrics. Moreover, the issues of existing
methods and the research gaps considering conventional MRI reconstruction schemes are elaborated
to obtain improved contribution for devising significant MRI reconstruction techniques.
Results: The proposed method will reduce conventional aliasing artifact problems, may attain lower
Mean Square Error (MSE), higher Peak Signal-to-Noise Ratio (PSNR), and Structural SIMilarity
(SSIM) index.
Conclusion: The issues of existing methods and the research gaps considering conventional MRI
reconstruction schemes are elaborated to devising an improved significant MRI reconstruction technique.
Keywords:
Magnetic resonance imaging, reconstruction, compressive sensing, penalty-aided minimization function, meta-
heuristic optimization.
