How deep is an MRI machine?

Published in MRI Technology 2 mins read

An MRI machine isn't measured by its depth, but rather by the diameter of its bore, which is the tunnel patients go into. A typical MRI machine has a bore with a diameter of 23.6 inches, or 60 centimeters.

Understanding MRI Bore Size

The "depth" of an MRI is really the length of the bore. However, the most relevant dimension is its diameter. Imagine the MRI machine as a large donut; patients lie inside the hole (the bore). Here's a breakdown:

MRI Bore Dimensions

Dimension Measurement
Diameter 23.6 inches (60 centimeters)
Shape Cylindrical or Tunnel-like

Key Insights about MRI Machines:

  • The Bore: The central opening where the patient lies down. This is crucial for imaging, as it positions the patient within the magnetic field.
  • Traditional vs. Open MRI: While the standard bore has a diameter of about 23.6 inches, there are also "open" MRI machines with wider or even open sides to accommodate people with claustrophobia or larger body sizes.
  • Imaging Technique: The machine uses a strong magnet and radio waves to create detailed images of the body. The patient needs to be inside the bore for this to work.

Practical Implications

  • Patient Comfort: The size of the bore can impact patient comfort, particularly for individuals who are anxious about enclosed spaces.
  • Medical Imaging: The bore size is designed to provide adequate space for accurate imaging while maintaining a strong magnetic field.
  • Variations: While 23.6 inches is a common diameter, some machines may vary slightly, especially open MRIs.

In summary, while the term "depth" can be used colloquially to refer to the bore, the measurement commonly used to describe the "depth" of the MRI machine is actually the 23.6 inch or 60 centimeter diameter of the bore.
