Embodiment Construction

[0024] Embodiments of the present invention will be described with reference to the drawings. Such as figure 1 As illustrated, a blood flow visualization diagnosis device 1 according to an embodiment of the present invention is connected to a detection device 2 for detecting flow velocity information of blood flowing in a blood vessel in the body. In addition, this blood flow visualization diagnosis device 1 includes a control unit 11 , a storage unit 12 , an operation unit 13 , a display unit 14 , and an input interface 15 .

[0025] The control unit 11 is a program control device such as a CPU, and operates according to a program stored in the storage unit 12 . In the present embodiment, the control unit 11 obtains the flow velocity information of the blood flowing in the blood vessel in the body from the detection device 2, and calculates the blood pressure in the blood vessel through an arithmetic formula that does not directly include the blood pressure in the blood vess...

Abstract

The subject of the invention is to provide a blood flow visualizing diagnostic device which can visualize and indicate quantities relating to the energy efficiency of a blood flow that are measured in an actual patient so as to improve the usefulness. A blood flow visualizing diagnostic device, whereby: flow rate data of blood flowing in a blood vessel in vivo is acquired; on the basis of the flow rate data thus acquired, energy losses of the blood flow are calculated, according to an arithmetic expression, said arithmetic expression not explicitly including the blood pressure in the blood vessel, at multiple representative points in an area of interest within the blood vessel; and then an image showing the extents of energy loss at the multiple representative points thus calculated is formed.

Description

technical field [0001] The present invention relates to a blood flow visualization diagnosis device for visualizing information related to blood flow flowing in a blood vessel in the body. Background technique [0002] As techniques for visualizing blood flow flowing through blood vessels in the body, methods using computer simulation, methods using an ultrasonic diagnostic device, methods using MRI (Magnetic Resonance Imaging, Magnetic Resonance Imaging), and the like are known. [0003] Among them, the method using computer simulation can obtain various information related to the blood flow, but it is generally not an actual measurement of a patient's blood vessel, so it cannot be used for diagnosis. In addition, in the method using an ultrasonic diagnostic apparatus or MRI, it is possible to detect the actual condition of the patient and obtain information on the flow velocity of blood in the blood vessel. However, by obtaining and visualizing only the blood flow velocit...
