The invention relates to quality control devices and methods for magnetic resonance
imaging (MRI) systems, more particularly for medical imaging applications. An example is
stereotactic surgery where MRI images are combined with X-ray images to accurately
locate a target in a subject.
A test device (1), and an associated method using said test object, are used to
easily detect a faulty calibration or a malfunction of an MRI device.
The test device includes:
a hermetically sealable hollow body (20) having a substantially cylindrical shape,
a support frame (22) configured to be removably inserted in the hollow body and
defining a target region (V22) having a substantially cylindrical shape; and
a plurality of target objects (24) made of a material visible on X-ray images and MRI
images said target objects being arranged in the target region and being attached to the
support frame.
