Ultrasonic diagnostic apparatus, ultrasonic diagnostic method, and recording medium

An ultrasonic diagnostic method comprising:

• displaying an ultrasonic image on a screen;
• in response to a screen mirroring request made by a portable terminal connected via a network, starting a session with the portable terminal for image transmission;
• and
• periodically transmitting contents displayed on the screen through the session, wherein,
• in response to the screen mirroring request made by the portable terminal, the method further comprising controlling:
• when a number of a previous session that has already been started is less than a session limit number, to start the session with the portable terminal that has made the screen mirroring request;
• and,
• when the number of the previous session that has already been started is equal to or greater than the session limit number,
• to acquire predetermined information, and
• to end the previous session that has already been started to newly start the session with the portable terminal that has made the screen mirroring request.

A non-transitory computer-readable recording medium storing a program executable by a computer, the program causing a computer of an ultrasonic diagnostic apparatus that includes a hardware processor that:

• displays an ultrasonic image on a screen;
• in response to a screen mirroring request made by a portable terminal connected via a network, starts a session with the portable terminal for image transmission;
• and
• periodically transmits contents displayed on the screen through the session,
• in response to the screen mirroring request made by the portable terminal, to perform control:
• when a number of a previous session that has already been started is less than a session limit number, to start the session with the portable terminal that has made the screen mirroring request;
• and,
• when the number of the previous session that has already been started is equal to or greater than the session limit number,
• to acquire predetermined information, and
• to end the previous session that has already been started to newly start the session with the portable terminal that has made the screen mirroring request.
