A low-cost workstation for Magnetic Resonance Imaging (MRI) analysis was developed using a personal computer and public-domain software. This flexible system efficiently processes MR images for common laboratory needs.

Area of Science:

  • Medical Imaging
  • Computational Science

Background:

  • Magnetic Resonance Imaging (MRI) analysis often requires specialized and expensive workstations.
  • There is a need for cost-effective and accessible solutions for MRI data processing in laboratory settings.

Purpose of the Study:

  • To demonstrate the feasibility of a low-cost, user-friendly workstation for MRI analysis.
  • To evaluate the suitability of public-domain software for processing MRI data.

Main Methods:

  • Implementation of a workstation using a Pentium personal computer running the Linux operating system.
  • Utilizing Khoros software, a general-purpose signal processing package, for MR image analysis.
  • Development of custom workspaces for 2D/3D image reconstruction, apodization, zero-filling, apparent diffusion coefficient (ADC) mapping, and image segmentation.
