<P>PROBLEM TO BE SOLVED: To provide diagnosis-supporting information preferable for diagnosis of lesions in a body cavity through which a contrast media passes. <P>SOLUTION: Images, wherein a site including a subject's esophagus through which the contrast media passes is continuously taken, are downloaded (S1), contour points, where test lines set across the esophagus and the contour of the esophagus intersect with each other on the taken image, are detected (S2 and S3), and the diagnosis-supporting information is generated based on change of positions of the contour points in a gas phase after passage of the contrast media (S4). The diagnosis-supporting information can include images which is trajectory of positional changes of the contour points, or information that presence of a lesion is decided when a positional change rate of the contour points exceeds a threshold, or the like (S5, S6 and S7). Thereby a change of the contour of the esophagus by the gas phase can be easily recognized, and a small lesion or a thinly spread lesion called scirrhous can be recognized. <P>COPYRIGHT: (C)2007,JPO&INPIT |
