PROBLEM TO BE SOLVED: To provide a diagnosis support device, a diagnosis support method, and a computer program capable of accurately evaluating blood vessel occlusion.SOLUTION: A diagnosis support device 100 includes a catheter 10, a pressure sensor 11, a flow velocity sensor 12, a signal processing part 20, and a data processing part 30. The catheter 10 is inserted into a pulmonary artery, and the pressure sensor 11 and the flow velocity sensor 12 are disposed in the blood vessel. A blood pressure and a pulse wave are measured by the pressure sensor 11, and a blood flow velocity is measured by the flow velocity sensor 12. The data processing part 30 generates diagnosis support information indicating a degree of occlusion of the blood vessel based on a phase difference between the blood pressure/pulse wave and the blood flow velocity, and outputs the diagnosis support information.SELECTED DRAWING: Figure 1 |
