Claim Text:
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 mechanism comprising a pressurizing surface that applies a pressing force to the subject to cause pressurizing displacement; a displacement-related-amount detector that detects a displacement related amount relating to displacement of the subject; an elastic-image displacement measuring circuit 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 circuit that calculates an elastic modulus of the subject based on the imaging displacement amount; a pressurizing-control displacement measuring circuit 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 mechanism; and a pressurizing mechanism control circuit that controls the pressurizing mechanism based on the controlling displacement amount.
