Summary:Disclosed herein is a medical system (100, 300) in which execution of machine executable instructions causes the computing system to: receive (200) a time series (122) of R2 star maps for a brain volume (500); receiving (202) a stimulation signal (124) describing the occurrence of sensory stimulation; receiving (204) a selection (126) of one or more seed voxels identified in the time series of the R2 star map; calculating (206) a de-noising time series (128) of the R2 star map; calculating (208) a correlation map (130) between the seed voxels and the series of de-noised times in the R2 star map; determining (210) an activation region (132) of the brain volume using voxels identified in the correlation map; providing (212) a hemodynamic response function (134) for each voxel and each occurrence of the sensory stimulus; and providing (214) a subject-specific hemodynamic response function (136) by averaging the hemodynamic response function. 本文公开了一种医学系统(100、300)，其中，对所述机器可执行指令的运行使所述计算系统：接收(200)针对脑部体积(500)的R2星图的时间
