Medical Video Data Processing Device

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medical video data processing apparatus. In particular, a medical examination monitors a picture-archive and communication system (PACS) because only a endoscopic monitor is examined and a procedure is performed due to a busy medical examination. If it is not confirmed, the patient's detailed (recent and past) medical information can be performed without checking, and it is thought that the image was taken during the examination, but the normal image is not taken, which may cause problems.

In addition, the present invention is proposed to solve the problem of checking whether the picture or video was taken during the test, the object of the present invention is the display function and endoscope of the picture archiving and communications system (PACS) The present invention relates to a medical video data processing device for simultaneously implementing a real-time monitor function of a screen.

For the purpose of diagnosing diseases, hospitals use medical imaging modalities such as X-ray, computed tomography (CT), and positron emission tomography (CT). The medical imaging apparatus photographs a patient's body and then generates a plurality of medical images. The medical images are converted into a digital imaging and communications in medicine (DICOM) file and then the medical images. Provided to medical staff by Picture Archiving and Communications System (PACS).

Medical images acquired by medical imaging apparatuses are regulated so that original images cannot be damaged.

Therefore, even if the medical image is not suitable due to the inappropriate size of the medical image, the original medical image cannot be edited by damaging the original image, and the medical-image-storage-transmission system (PACS) screen and the endoscopy screen can be separately It has to be monitored and it causes inconvenience because it takes a long time to reboot if the operating system has a problem.

Therefore, in order to solve the existing prior literature [Patent Document 1] Republic of Korea Patent Publication No. 10-1447829, Publication Date 2014. 10. 08. (hereinafter referred to as [Patent Document 1]) the electronic obligation record (EMR: We unveiled an integrated system of Electronic Medical Record (PAC) and Picture Archiving and Communications System (PACS).

In [Patent Document 1], the electronic medical record in one system by integrating the Electronic Medical Record (EMR) and Picture Archiving and Communications System (PACS) functions into one system. It is a technical feature to provide an integrated system of electronic medical records and medical-image-storage-transmission systems capable of synchronizing human or animal patient information in a database and a medical-image-storage-transmission system database.

In addition, Republic of Korea Patent Publication No. 10-2016-0145269, Publication Date December 20, 2016 (hereinafter referred to as "Patent Document 2") disclosed a medical image editing device and editing method.

[Patent Literature 2] relates to a medical image editing apparatus and an editing method, and it is a technical feature that the user can edit and use only a desired part without damaging the original image of the medical image.

In addition, Republic of Korea Patent Publication No. 10-0343887, Publication Date July 20, 2002 (hereinafter referred to as [Patent Document 3]) disclosed a DICOM management device for PACS.

In [Patent Document 3], an image is obtained from an imaging device that supports DICOM (Digital Imaging and Communications in Medicine) and an imaging device that does not support medical-digital image-communication. It provides a management device for medical-digital image-communication for medical-image-storage-transmission system (PACS) that can use the international convention standard DICOM 3.0 file format when handing over data.

However, in the existing [Patent Documents 1] to [Patent Documents 3], medical video data is monitored, and a medical-image-storage-transmission system (PACS) screen and an endoscopy screen are output on each screen and simultaneously monitored. Since the power is not disconnected, the entire system must be rebooted including the real-time display screen used in the clinical practice when an embedded system error occurs. Therefore, the clinical practice is delayed during the reboot time.
