PACS is the image archiving and transmission system, which is the product of the combination of medical imaging, digital image technology, computer technology and network communication technology. It is a computer application program for the collection, storage, reporting, output, management and query of various medical image information .
PACS is a medical image management system based on the DICOM standard. Its modules cover various functions from image acquisition/transmission/storage/processing, patient information management, diagnosis report editing/management to comprehensive query statistics, etc., supporting CT, MR, CR, DR, ECT, DSA, X-ray machine, ultrasound, endoscopy, pathology and other equipment.
The medical imaging PACS system can realize a series of functions to meet the daily work of the imaging department, such as examination appointment, patient information registration, computer reading, electronic report writing, film printing, data backup, and due to the digital storage of images, users can use image processing and measurement Technology-assisted diagnosis, convenient and quick search for data or transmission of data to clinical departments through the network, and seamless connection with hospital HIS and LIS.
Specially designed for the hospital workflow, the PACS system fully meets the needs of the hospital, and is equipped with flexible radiology information solutions. Standard interface protocol is adopted to realize appointment registration, report diagnosis, image browsing and processing, information statistics and other functions.
