A new imaging phantom called a 'fusion phantom' enhances the efficiency of performance testing and quality control. The phantom relocates the test elements of a standard MRI phantom, and provides a configuration of inner containers that enables simultaneous performance testing on magnetic resonance imaging and magnetic resonance spectroscopy within a predetermined error range. The fusion phantom is useful for multi-purpose performance testing of magnetic resonance imaging equipment, including correlation analysis, performance testing, system management and the like in the diagnosis field. The fusion phantom enhances efficiency of time and reliability in testing performance of the magnetic resonance imaging equipment, adjusts incorrect position accuracy and improves quality of images.

A new multi-purpose phantom evaluates the performance of an ultra high field Magnetic Resonance Imaging (MRI) apparatus. The phantom can assess a degree of diagnostic capability of an MRI apparatus using imaging conditions and variables and simultaneously analyze and evaluate performance of Magnetic Resonance Imaging (MRI), performance of Magnetic Resonance Spectroscopy (MRS) and metabolic components of a human body within a predetermined range of error and limit.

The invention relates to an MRI system, comprising: an examination table including a cradle in which a patient may be positioned; a magnetic assembly disposed in the examination table and including first and second electrode assemblies, the respective electrode surfaces of which are disposed so as to be perpendicularly spaced apart by a certain distance and opposite each other such that space for imaging may be formed therebetween; and an RF coil unit contactingly or contactlessly attached to a part of a patient to be examined or an attached part corresponding to the part to be examined, applying an RF pulse to the part of the patient to be examined, and detecting an MR signal from the examined part.

Provided is a phantom for evaluating the accuracy of image registration software based on a result of matching tomograms of a predetermined position of the phantom, taken using two or more imaging apparatuses. Accordingly, it is possible to more efficiently evaluate the accuracy of the image registration software by comparing the tomograms with one another using a three-dimensional analysis. In addition, it is possible to facilitate the comparison of the tomograms with one another by installing a plurality of indicating bars in the phantom so that their cross sections can appear on each of the tomograms.
