Propose it is a kind of for analyzing the technical solution of the physical feeling of patient, before carrying out the method the physical feeling be poured can patients body recycle and be substantially secured to the contrast agent on biological target. Corresponding method(A1-A18)Including providing(A1-A2)At least one filtered image,The filtered image includes multiple filter values of the corresponding position for physical feeling,Each filter value includes the instruction in the immobilization contrast agent of corresponding position,The contribution for wherein recycling contrast agent significantly reduces,It generates(A17)The image through thresholding comprising multiple threshold values corresponding with filter value,Image through thresholding is generated and setting corresponding filter value or reset value for each threshold value with the comparison result of amplitude thresholds according to filter value,It provides(A3-A7)The multiple candidate thresholds defined by the correspondence candidate value of amplitude thresholds,It generates(A8)Multiple candidate images corresponding with candidate thresholds,Each candidate image includes multiple candidate values corresponding to filter value,Each candidate image be by by each candidate value be set as corresponding filter value or according to filter value with candidate thresholds it is described compared with reset values generate,It calculates(A9-A14)Multiple fiducial values corresponding with candidate image,The fiducial value of each candidate image calculates compared with further between the candidate value in race way according to the candidate value in fixed area,The fixed area corresponds to one group of position of the immobilization contrast agent comprising significant quantity,The race way corresponds at least part for eliminating the position of fixed area,It determines(A15)The peak value of fiducial value,And it is arranged according to the peak value of fiducial value(A16)Amplitude t
