DISPOSITIF D'OBSERVATION À ULTRASONS, PROCÉDÉ D'EXPLOITATION DU DISPOSITIF D'OBSERVATION À ULTRASONS ET PROGRAMME D'EXPLOITATION DU DISPOSITIF D'OBSERVATION À ULTRASONS
This ultrasonic observation device transmits ultrasonic waves toward an observed object, and causes a display device to display an ultrasound image generated on the basis of an ultrasound signal received from an ultrasonic transducer which receives ultrasonic waves reflected by the observed object. The ultrasonic observation device is provided with an operation control unit which controls the shape of a region of interest set within the ultrasound image, in accordance with a change in a position of contact of a contacting object in contact with a touch pad of an input device. The operation control unit detects the position of contact of the contacting object on the touch pad, calculates a first positional relationship based on two positions of contact on the touch pad, detects the position of the region of interest set within the ultrasound image, calculates a second positional relationship based on the position at which the region of interest has been set and a reference position, and controls the shape of the region of interest on the basis of a correlation between the first positional relationship and the second positional relationship. The present invention thus provides an ultrasonic observation device with which it is possible for an operation to be performed intuitively when reducing or increasing the size of the region of interest.La présente invention concerne un dispositif d'observation à ultrasons qui transmet des ondes ultrasonores vers un objet observé et amène un dispositif d'affichage à afficher une image ultrasonore générée sur la base d'un signal ultrasonore reçu en provenance d'un transducteur à ultrasons qui reçoit les ondes ultrasonores réfléchies par l'objet observé. Le dispositif d'observation à ultrasons est pourvu d'une unité de commande d'opération qui commande la forme d'une région d'intérêt définie à l'intérieur de l'image ultrasonore, en fonction d'un changement dans la position de contact d'un objet de contact en contact avec un pavé tac
