A new, low-cost desktop magnetic resonance imaging (MRI) system was developed using consumer electronics. This affordable MR scanner offers a promising solution for routine research and educational laboratory use.

Area of Science:

  • Medical Imaging
  • Biophysics
  • Engineering

Background:

  • Modern magnetic resonance imaging (MRI) systems are complex and expensive, limiting their accessibility to hospitals and specialized labs.
  • Advances in consumer electronics offer potential for developing more affordable and compact MR systems.
  • Current MR technology is often impractical for routine laboratory research and education due to cost and complexity.

Purpose of the Study:

  • To develop a small, low-cost magnetic resonance (MR) system suitable for routine laboratory use.
  • To leverage inexpensive, high-performance consumer electronics components for MR scanner construction.
  • To demonstrate the feasibility of a desktop MR scanner for research and educational applications.

Main Methods:

  • Developed a prototype desktop MR scanner using a 0.21 T permanent magnet.

  • Utilized commercially available components and inexpensive radio-frequency integrated circuits.
  • Programmed the system using LabVIEW software for a 2 cm imaging region.
  • Acquired 3D data sets from resolution phantoms and fixed, newborn mice.

    • Main Results:

    • Successfully constructed a functional desktop MR scanner for approximately $13,500.
    • Demonstrated the system's capability to acquire useful 3D images.
    • Achieved imaging of resolution phantoms and biological samples (newborn mice).

    Conclusions:

    • The developed low-cost desktop MR scanner is a viable tool for research and education.
    • This system makes advanced MR imaging more accessible for laboratory settings.
    • The use of consumer electronics components significantly reduces the cost and complexity of MR systems.
