Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Intelligent Optimization Algorithms (IOA) improve Magnetic Resonance Imaging (MRI) denoising. Immune Algorithm (IA) offers superior threshold optimization for Adaptive Template Filtering Method (ATFM) compared to Genetic Algorithm (GA).

Area of Science:

  • Medical Imaging
  • Artificial Intelligence
  • Image Processing

Background:

  • Magnetic Resonance Imaging (MRI) exhibits complex gray-level changes, challenging traditional filtering methods.
  • Adaptive Template Filtering Method (ATFM) is suitable for MRI denoising but requires optimal threshold selection.
  • Current threshold selection for ATFM relies on experience, lacking a robust theoretical basis.

Purpose of the Study:

  • To propose and evaluate Intelligent Optimization Algorithms (IOA) for optimizing ATFM thresholds in MRI.
  • To compare the performance of Immune Algorithm (IA) and Genetic Algorithm (GA) for this specific application.
  • To enhance the denoising capabilities of ATFM through optimized thresholding.

Main Methods:

  • Implementation of two types of Intelligent Optimization Algorithms (IOA): Immune Algorithm (IA) and Genetic Algorithm (GA).
