ULTRASOUND OBSERVATION SYSTEM

摘要

An ultrasound observation system includes an ultrasound transducer that generates an ultrasound signal by transmitting and receiving ultrasound to and from a subject, an automatic pressurizing mechanism that applies a pressing force to the subject to cause pressurizing displacement, an elastic-image-generation displacement measuring circuit that measures an imaging displacement amount of the subject based on the ultrasound signal, an elastic modulus calculation circuit that calculates an elastic modulus of the subject based on the imaging displacement amount, a pressurizing-mechanism-control displacement measuring circuit that measures a controlling displacement amount in accordance with spontaneous displacement of the subject based on the ultrasound signal, and a pressurizing mechanism control circuit that controls the automatic pressurizing mechanism based on the controlling displacement amount.

1. An ultrasound observation system for transmitting ultrasound to a subject, receiving the ultrasound reflected by the subject, and generating an image based on an ultrasound signal obtained by the received ultrasound, the ultrasound observation system comprising:
an ultrasound transducer that transmits the ultrasound to the subject, receives the ultrasound reflected by the subject and generates the ultrasound signal from the received ultrasound; a pressurizing section that applies a pressing force to the subject to cause pressurizing displacement; a displacement-related-amount detecting section that detects a displacement related amount relating to displacement of the subject; an elastic-image displacement measuring section that measures an imaging displacement amount of the subject based on the ultrasound signal so as to generate an elastic image of the subject; an elastic modulus calculation section that calculates an elastic modulus of the subject based on the imaging displacement amount; a pressurizing-control displacement measuring section that measures a controlling displacement amount in accordance with spontaneous displacement of the subject based on the displacement related amount so as to control the pressurizing section; and a pressurizing control section that controls the pressurizing section based on the controlling displacement amount.
