Display device and system for ultrasound image, and method for detecting size of biological tissue by using same

An ultrasound image display system comprising:

• an ultrasound image diagnosis apparatus configured to generate ultrasound image data corresponding to biological tissue using an ultrasound probe and to transmit the generated ultrasound image data;
• and
• a display device configured to receive the ultrasound image data from the ultrasound image diagnosis apparatus and to display an ultrasound image corresponding to the ultrasound image data using the received ultrasound image data,
• wherein the display device comprises:
• an input/output interface portion comprising a touch screen configured to display the ultrasound image, and to recognize a touch point of a user who touches the touch screen on which the ultrasound image is displayed;
• an edge detection portion configured to detect at least one edge part adjacent to the recognized touch point in the ultrasound image;
• and
• a control portion configured to control an edge curve corresponding to the detected edge part to be displayed on the touch screen while being overlapped with the ultrasound image and to detect size information of the biological tissue according to a type of the displayed edge curve, and
• wherein the input/output interface portion is configured to output the detected size information under the control of the control portion,
• wherein the control portion is configured to determine whether the type of the edge curve is an open curve or a closed curve, and
• wherein when the type of the edge curve is the open curve, the control portion is configured to detect, as the size information, a distance between virtual touch points at which extended virtual normal lines perpendicular to two open edge curves formed on both sides of the touch point meet the open edge curves.

A method of detecting a size of biological tissue using an ultrasound image display device, the method comprising:

• displaying an ultrasound image of biological tissue on a touch screen;
• recognizing a touch point of a user who touches the touch screen on which the ultrasound image is displayed;
• detecting at least one edge part adjacent to the recognized touch point from the ultrasound image;
• displaying, on the touch screen, an edge curve corresponding to the detected edge part to be overlapped with the ultrasound image;
• and
• detecting size information of the biological tissue according to a type of the displayed edge curve;
• and
• outputting the detected size information,
• wherein the detecting of the size information of the biological tissue includes determining whether the type of the edge curve is an open curve or a closed curve, and detecting, when the type of the edge curve is the open curve, as the size information, a distance between virtual touch points at which extended virtual normal lines perpendicular to two open edge curves formed on both sides of the touch point meet the open edge curves.
