PROBLEM TO BE SOLVED: To achieve easy operation and check of an ultrasonic image even when an operator is away from an ultrasonic diagnostic device.SOLUTION: An ultrasonic diagnostic system has an ultrasonic diagnostic device and a terminal device which is communicably connected to the ultrasonic diagnostic device. The ultrasonic diagnostic device has: a first display section； an image generating section for performing predetermined image processing to image data including ultrasonic image data to generate a display image； a display control section for allowing the image generating section to generate a first display image which is to be displayed on the first display section and allowing the first display section to display the first display image thereon； and a communication control section for allowing the image generating section to generate a second display image which is different from the first display image regarding at least one of the resolution and the frame rate and allowing a communication section to transmit the second display image to the terminal device. The terminal device has: a second display section； and a terminal control section for allowing the second display section to display the second display image transmitted from the ultrasonic diagnostic device.
