## Abstract

An ultrasonic diagnostic apparatus includes a hardware processor that: displays an ultrasonic image on a screen; in response to a screen mirroring request from 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 from the portable terminal, the hardware processor performs control: when a number of a previous session already 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 already started is equal to or greater than the session limit number, to acquire predetermined information, and to end the previous session already started to newly start the session with the portable terminal that has made the screen mirroring request.

## Claims

### Claim 1

An ultrasonic diagnostic apparatus comprising 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, wherein,
in response to the screen mirroring request made by the portable terminal, the hardware processor performs 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.

### Claim 2 (depends on 1)

The ultrasonic diagnostic apparatus according to claim 1, wherein, when the number of the previous session that has already been started is equal to or greater than the session limit number, the hardware processor
acquires information on at least one of a previous portable terminal that has already been connected via the previous session, and
ends at least one of the previous session that has already been started with the previous portable terminal that has already been connected to newly start the session with the portable terminal that has made the screen mirroring request.

### Claim 3 (depends on 1)

The ultrasonic diagnostic apparatus according to claim 1, wherein, when the number of the previous session that has already been started is equal to or greater than the session limit number, the hardware processor performs control to output, to the portable terminal that has made the screen mirroring request, selection screen information that allows a selection to be made on the portable terminal that has made the screen mirroring request, the selection being whether 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 or to withdraw the screen mirroring request.

### Claim 4 (depends on 1)

The ultrasonic diagnostic apparatus according to claim 1, wherein, when the number of the previous session that has already been started is equal to or greater than the session limit number, the hardware processor allows a selection as to whether 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 or to reject the screen mirroring request.

### Claim 5 (depends on 1)

The ultrasonic diagnostic apparatus according to claim 1, wherein when the number of the previous session that has already been started is equal to or greater than the session limit number, the hardware processor ends a session that has been started earliest among the previous session that has already been started.

### Claim 6

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.

### Claim 7

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.
