Abstract: The present invention relates to an external standard reference system of a type inserted into the coil of a human magnetic resonance imaging equipment, and more specifically, to a system capable of analyzing metabolic components (quantity of metabolites) in a human body without an error and a limited range using an external standard reference analysis method, in order to enhance accuracy of diagnosis by utilizing magnetic resonance spectroscopy of the human magnetic resonance imaging equipment. A system for evaluating performance of magnetic resonance spectroscopy includes an outer container for inserting an RF coil and provided with a plurality of holes; a plurality of inner containers arranged to be inserted into the plurality of holes respectively and capable of being filled with metabolites different from each other in at least a type or a concentration; and a frame for fixing a head of an object arranged inside the outer container.

Abstract: 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.

Abstract: 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.
