The present invention relates to correcting flow estimation inside an anatomy. In order to provide a further improved flow estimation, a method (100) for correcting flow estimation of a fluid inside an anatomy is provided having the following steps: A temporal sequence of at least two images of the anatomy is provided (102) comprising data of an identifiable fluid. The anatomy comprises at least one lumen within enclosing walls and filled with a flowing fluid. Further, data of a border region inside the anatomy along the enclosing walls and data of a remaining main region inside the at least one lumen is provided (104). Next, a flow inside the lumen is estimated (106) based on the temporal sequence of at least two images. The estimation comprises estimating a constrained flow for the border region. In the constrained flow, flow vectors of the estimated flow are corrected by a correction. Further, the constrained flow and an estimated flow in the main region are combined (108) to form a corrected flow field. The corrected flow field is then displayed (110). |
