Detect distortion of MR images

The THETIS 3D MR Distortion Phantom serves to detect possible distortion of MR images reliably and quickly. It contains small markers arranged in a square grid that provide a strong, localized MR signal. By determining the amount of distortion of the square grid or signal loss on the MR image, possible image distortion can be detected by the user. The phantom is aligned to the isocenter or the image center of the MR unit using LAP MR laser systems and can be aligned easily and quickly using the integrated leveling aids.

Features

Modular

Modular expansion stages allow optimal adaptation to different requirements thus ensuring efficient workflows.

MR-safe

THETIS 3D MR Distortion Phantom contains no ferromagnetic components and is therefore ideally suited for the MR environment.

Easy handling

Integrated leveling aids enable uncomplicated and fast alignment. The intuitive handling of the phantom makes 3D examination of the entire MRI space easy.
