Spatial tagging methods such as SPAMM provide information about tissue displacement during movement, however the analysis of tag position is time consuming and subjective. Using the proposed semi-automated method, it was possible to detect tag position in any image plane for spatial line tags. This decreased analysis time and subjectivity of tag detection. The method described is accurate to <0.03% for static images and can be applied to dynamic images as well.
