Embodiment Construction

[0043] The ultrasonic diagnostic apparatus according to the present invention determines the moving speed of each region of the object to be measured and the modulus of elasticity and the amount of expansion and contraction in the minute-sized region. The measured object itself does not move. In particular, the ultrasonic diagnostic apparatus of the present invention is suitable for measuring the elastic modulus of each region of a living body and has high spatial resolution. For this purpose, preferably, it can be used to measure the expansion and contraction and the modulus of elasticity of the vessel wall. A description will be given below of the case of measuring the expansion, contraction, and modulus of elasticity of the blood vessel wall.

[0044] A brief description of an embodiment of the ultrasonic diagnostic apparatus according to the present invention will be given below. FIG. 1 is a schematic block diagram showing an arrangement for diagnosing the condition and ...

Abstract

A technology to provide ultrasonic diagnostic equipment and ultrasonographic diagnosis of vascular endothelial function with high sensitivity by measuring changes in elastic modulus of vascular intima and media with high precision by using ultrasonic waves of vascular endothelial reaction after diagnostic exsanguination equipment. The ultrasonic diagnostic equipment is provided with a calculation unit (19) for determining the elastic modulus of the blood vessel wall (4), and at least any calculation data storage unit (20) or display unit (21), and the storage unit (20) stores The change of the elastic modulus of the arterial vessel wall with time when the artery is expelled and then stopped, and the display unit (21) displays the change of the elastic modulus of the vessel wall with time.

Description

technical field [0001] The present invention relates to an ultrasonic diagnostic device for diagnosing the condition and behavior of blood vessel wall tissue using ultrasonic waves. The invention also relates to an ultrasonic diagnosis method. Background technique [0002] In recent years, the number of patients suffering from circulatory organ diseases such as myocardial infarction, cerebral infarction, etc. has increased, and prevention and treatment of these diseases is now an important issue. [0003] The development of myocardial infarction or cerebral infarction is closely related to atherosclerosis. More specifically, when atheroma forms on the artery wall or new cells of the artery cannot be formed due to various reasons such as high blood pressure, the artery loses its elasticity and hardens and becomes brittle. Atherosclerosis flows into a blood vessel when a blood vessel becomes blocked at the portion where the atheroma has formed or when the vascular tissue sur...
