REDUCTION OF LYMPH TISSUE FALSE POSITIVES IN PULMONARY EMBOLISM DETECTION

摘要

A system for automatically detecting pulmonary emboli from medical image data includes receiving image data (S101 ), automatically detecting one or more pulmonary embolism candidates from the image data (S 102), segmenting an airway tract from the image data (S 103), segmenting an artery structure from the image data (S 103), calculating a distance between each of the candidates and a nearest portion of the segmented airway (S 104), determining whether each of the candidates is within or outside of the segmented artery structure (S 105), rejecting candidates based on the calculated distance between each of the candidates and the nearest portion of the segmented airway and the determination as to whether each of the candidates is within or outside of the segmented artery structure (S 106), and indicating the location of the non-rejected candidates within the image data (S 107).
