摘要:
The present invention is to increase the efficiency in the performance evaluation and quality control of the magnetic resonance system One such, designed to evaluate the performance to be received simultaneously by a fused phantom, is produced. The Phantom in the image condition and determine the performance level of a magnetic resonance system with a total result of the picture variable to be the performance evaluation and performance evaluation of magnetic resonance spectroscopy of magnetic resonance imaging within a certain error range at the same time, a standard MRI on existing that the evaluation factor of a relocating ACR-MRI phantom used in phantom, inserted into the inner container layer. Change the type and concentration of the various imaging and spectroscopy brain metabolites obtained when a fusion is a fusion phantom by phantom to the quantitative evaluation and analysis. Mutual affinity analysis of the fusion phantom for a magnetic resonance imaging (MRI) and MR spectroscopy performance evaluation of the present invention is in the diagnosis region by using the optimized assay that can be performed at the same time as existing ACR-MRI phantom and MRS phantom, performance evaluation, the system overall management can be used for multi-purpose performance evaluation of the MRI equipment. The present invention corrects the incorrect positioning accuracy as well as to increase the confidence in the temporal efficiency and endpoints as fusion phantom for a magnetic resonance imaging (MRI) and MR spectroscopy performance evaluation to evaluate the performance of the magnetic resonance imaging equipment, the quality of the image The improvement can be obtained with a phantom.본 발명은 자기공명 시스템의 성능평가 및 정도관리에 효율성을 높이도록 한 것으로서, 성능평가를 하나의 융합된 팬텀으로 동시획득이 가능하도록 설계, 제작한 것이다. 영상조건과 영상변수의 총체적 결과로 자기공명 시스템의 수행능력 정도를 파악하여 일정한 오차범위 내에서의 자기공명영상의 성능평가 및 자기공명분광의 성능평가를 동시에 할 수 있는 팬텀이며, 기존에 표준 MRI 팬텀으로 사용되고 있는 ACR-MRI 팬텀의 평가요소를 재배치한 것으로, 층으로 된 내부용기를 삽입하였다. 융합 팬텀으로서 다양한 영상 및 분광 획득
