the present invention is an ultrasonic diagnostic apparatus for actively compressing the ultrasound image in accordance with the communication quality and its operating method of that, the ultrasonic diagnostic apparatus from recording the ultrasound image PACS (Picture Archiving and Communication System) via transmission case, the ultrasound system to a connected network of quality in accordance actively ultrasound image of the lossy or lossless compression to by transmitting, than the ultrasonic efficiently compressed ultrasound image actively in accordance with the communication quality which can transmit ultrasound image diagnosis apparatus and to a method for its operation. The ultrasound diagnostic apparatus for actively compressing ultrasound images based on the communication quality of the present invention stores the ultrasonic diagnostic apparatus and the ultrasonic image to generate the ultrasound image, the 3D ultrasound taken inside the body to the digital data, to read and transmit PACS (Picture Archiving Communication System) and the ultrasonic image of the received reading to for remote diagnostic apparatus and the ultrasonic diagnostic apparatus and remotely located ultrasound diagnostic apparatus in the generated ultrasound image of an integrated storage and stored in the ultrasound image, the ultrasound system, the PACS , has a technical meaning as the remote diagnostic or comprises a cloud server for providing to one or more of the ultrasonic diagnostic apparatus located in the remote.본 발명은 통신 품질에 따라 초음파 이미지를 능동적으로 압축하는 초음파 진단 장치 및 그 운영방법에 관한 것으로, 초음파 진단기로부터 촬영된 초음파 이미지를 PACS(Picture Archiving and Communication System)를 통해 전송하는 경우, 초음파 진단기에 연결된 통신망의 품질에 따라 능동적으로 초음파 이미지를 손실 압축 또는 무손실 압축하여 전송함으로써, 보다 효율적으로 초음파 이미지를 전송할 수 있는 통신 품질에 따라 초음파 이미지를 능동적으로 압축하는 초음파 진단 장치 및 그 운영방법에 관한 것이다.본 발명의 통신 품질에 따라 초음파 이미지를 능동적으로 압축하는 초음파 진단 장치는 신체의 내부를 3차원 초음파 촬영하여 초음파 이미지를 생성하기 위한 초음파 진단기와 상기 초음파 이미지를 디지털 데이터로 저장, 판독 및 전송하기 위한 PACS(Picture Archiving Communication S
