中文摘要 | 即時性功能磁振造影需要線上的影像重組、運動位移修正的影像重新排列及統計功能分析,線上處理系統可提供研究者即時的回饋及功能性磁振造影的品管控制;藉助AFNI(Analysis ofFunctional NeuroImage, Medical College of Wiscosin, WI, USA)影像軟體,研發自裝式線上功能磁振造影分析系統,藉手部運動工作,於六位正常自願受試者及一位硬腦膜瘤病患測試其檢查中的運動位移及功能分析。 於一般功能性磁振造影檢查下,使用Octane工作站可於40秒內獲得線上處理結果,此線上功能磁振造影分析系統可提供臨床功能性磁振檢查的應用及檢查設計的線上回饋,同時該系統無需額外經費並可應用於標準的臨床磁振造影系統。 |
英文摘要 | On-line image reconstruction, image realignment for motion correction, and statistical functional analyses are required during functional MRI (fMRI) acquisition for real-time processing. An on-line processing system provides the feedback system to investigators and on-line quality control of fMRI. By adapting the program, Analysis of Functional NeuroImage (AFNI, Medical College of Wisconsin, WI, USA), custom-designed image processing demonstrated on-line evaluation of motion displacement and functional analyses of 6 normal volunteers and a patient with meningioma by applying the paradigm of a motor task. With on-line processing during standard data acquisition at an Octane workstation, processing time was about 40 seconds after completion of image acquisition. On-line functional processing illustrates the potential applications in clinical functional studies and on-line feedback for fMRI experimental design. Easy implementation of the processing configuration can be realized in the standard clinical environment at no additional cost. |
