Abstract

An ultrasound system is provided to clearly display an ultrasound image changed according to user instruction by fixing a screen focus to a display part regardless of an input of the user instruction. An ultrasound system(100) includes a probe(110), a control panel(120), a main body(130), and a display part(140). The control panel includes a touch screen(121) and an input part(122). A user instruction is inputted to the touch screen. The main body forms an ultrasound image based on an external ultrasonic echo signal. The main body includes a control part(132). The control part fixes a screen focus for activating a screen regardless of the input of the user instruction to the display part. The display part displays the ultrasound image.

Description

Ultrasonic System {ULTRASOUND SYSTEM}

The present invention relates to the field of ultrasound, and more particularly, to an ultrasound system for fixing a screen focus for activating a screen to a display unit.

Ultrasound systems have non-invasive and non-destructive properties and are widely used in the medical field for obtaining information inside an object. Ultrasound systems can provide a high resolution image of internal tissues to a doctor in real time without the need for direct surgical surgery, which is very important in the medical field.

In general, the ultrasound system includes a probe, a main body, a control panel, and a display unit. The probe includes a conversion element formed of a piezoelectric material for transmitting and receiving ultrasonic signals. The probe electrically stimulates the conversion element to form and transmit an ultrasonic signal to the human body. The ultrasonic signal transmitted to the human body is reflected at the boundary of discontinuous human tissue, and the ultrasonic echo signal transmitted from the boundary of the human tissue to the conversion element is converted into an electrical signal. The main body performs focusing of the ultrasound signal and reception focus of the ultrasound echo signal, and forms an ultrasound image of the object based on the received focused signal. The control panel is provided on one side of the main body, and includes a touch screen, a keyboard, a trackball, a plurality of buttons, etc. for performing a function of acquiring and controlling an ultrasound image, a menu control function, a measurement and an annotation function, and the like. The display unit displays an ultrasound image formed in the main body.

Meanwhile, in order to display the ultrasound image formed in the main body on the display, the ultrasound system sets a screen focus for activating the screen and then displays the ultrasound image on the display. The ultrasound system converts the screen focus from the display unit to the touch screen when a user instruction is input from the user through the touch screen. When the input of the user instruction is completed, the ultrasound system switches the screen focus from the touch screen to the display unit.

Conventional ultrasound system has a problem that can not be clearly provided to the user how the ultrasound image displayed on the display unit without the screen focus changes according to the user instruction due to the above-described switching of the screen focus.

The present invention provides an ultrasound system for fixing a screen focus for activating a screen even when a user instruction is input through a touch screen.

According to an aspect of the present invention, there is provided an ultrasound system comprising: a main body operable to form an ultrasound image based on an ultrasound echo signal input from an external device; And a display unit operable to display the ultrasound image, wherein the main body is operable to fix the screen focus for activating the screen to the display unit.

According to the present invention, even if a user instruction is input through the control panel, the screen focus can be fixed to the display unit, so that an ultrasound image that changes according to the user instruction can be clearly provided to the user.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention.

1 is a block diagram showing the configuration of an ultrasound system 100 according to an embodiment of the present invention. The probe 110 includes a conversion element (not shown) formed of a piezoelectric material to transmit and receive an ultrasonic signal. The conversion element of the probe is electrically stimulated to form an ultrasonic signal transmitted to the human body, and transmits the formed ultrasonic signal to the human body. The ultrasonic signal transmitted to the human body is reflected at the boundary of the discontinuous human tissue, and the echo signal transmitted from the boundary of the human tissue to the conversion element is converted into an electrical signal.

The control panel 120 includes a touch screen 121 and an input unit 122. The touch screen 121 displays a menu for optimizing the ultrasound image, and receives an instruction of a user. In the present embodiment, the user instruction includes menu selection information through touching of the user. The input unit 122 may include a track ball (not shown) for receiving a user instruction corresponding to a movement of a cursor, a keyboard (not shown) for receiving a user instruction corresponding to a text, and a time gain compensation (TGG) of an ultrasound image. And a button unit (not shown) including a slider (not shown) for receiving a user instruction corresponding to the setting and a dial button, an up-down button, a knob button, and the like.

The main body 130 performs various signal processing of echo signals from the probe 110 based on user instructions from the control panel 120, forms an ultrasound image based on the processed echo signals, and displays the display 140. Display via. In the present embodiment, the main body 130 includes a control unit 132. The control unit 132 fixes the screen focus for activating the screen regardless of the input of the user instruction to the display unit. That is, even if a user instruction is input through the control panel, the controller 132 fixes the screen focus to the display 140 without setting the screen focus to the touch screen 121 from the display 140.

While the invention has been described and illustrated by way of preferred embodiments, those skilled in the art will recognize that various modifications and changes can be made without departing from the spirit and scope of the appended claims.
