The functionality of MRI, or magnetic resonance imaging, is based on magnetic fields, which aren’t perfectly accurate. This results in a need to make corrections to the images.
MRI devices are calibrated by detecting distortions with physical objects called ‘phantoms’. To detect distortions the measurement data are compared against the known dimensions of the phantom. The image can then be corrected by running a computer algorithm.
Our phantom is a 3D-printed grid of tubes that provides an accurate benchmark for the calibration of the MRI scanner. The design is very lightweight, to maximize usability. Our solution includes a concept for visualizing and analyzing the measurement data, which provides the MRI user a quick and easy way of seeing where the MRI is accurate.
