The present invention provides ultrasonic diagnostic equipment and a control method thereof, wherein the equipment prevents data from being reduced or omitted from a screen when displaying two or more kinds of ultrasonic data on a single screen. Also, the present invention provides ultrasonic diagnostic equipment and a control method thereof, wherein the equipment displays data, which was omitted from a screen, through just a simple operation of a user, thereby reducing operation steps of the user and enabling the user to intuitively compare and analyze data. The ultrasonic diagnostic equipment according to an embodiment of the present invention includes the following parts: a probe which transmits an ultrasonic signal to an object and receives a reflected ultrasonic signal a first mode image generation part which generates a first mode image based on the ultrasonic signal received by the probe a second mode image generation part which generates a second mode image related to the first mode image a display part which simultaneously displays the first mode image and the second mode image on a single screen and a display control part which, if a part of a first mode image portion, which is related to the second mode image, is not displayed on the display part, moves the first mode image displayed on the display part and enables the entire portion, which is related to the second mode image, to be displayed on the display part.COPYRIGHT KIPO 2014[Reference numerals] (110) Probe(120) Beam-former(130) Image signal processing part(140) Memory(150) First mode image generation part(160) Input part(170) Second mode image generation part(180) Display control part(190) Display part본 발명은 두 종류 이상의 초음파 데이터를 하나의 화면에 표시할 때 데이터가 축소되거나 화면에서 누락되는 것을 방지하는 초음파 진단 장치 및 그 제어방법을 제공한다. 또한, 본 발명은 사용자의 간단한 동작만으로 화면에서 누락된 데이터를 표시함으로써 사용자의 오퍼레이션 스텝을 줄이고, 사용자가 직관적으로 데이터의 비교, 분석을 수행할 수 있게 하는 초음파 진단 장치 및 그 제어방법을 제공한다.본 발명의 일 측면에 따른 초음파 진단 장치는 대상체에 초음파 신호를 조사하여 반사된 초음파 신호를 수신하는 프로브 상기 프로브로부터 수신된 초음파
