The purpose of this study was to design and manufacture an active BOLD simulation phantom, thus testing the stability and repeatability of the phantom. Three scanners were used to test the stability and repeatability of the BOLD signal detection of the phantom. It was found that the phantom had good stability and repeatability. The phantom can stably quantify the BOLD signal for fMRI quality control in different scanners. Consequently, the phantom can stably quantify the BOLD signal for fMRI quality control in different scanners.
