PACS (Picture Archiving and Comuniations Systems), image storage and transmission system, is an information system used in hospitals to manage medical images generated by medical equipment such as CT, MR, etc. The goal is to support all image-related activities within the hospital, integrating medical equipment, image storage and distribution, display of digital images during important diagnoses and consultations, image archiving, and external information systems.
PACS acquires, stores, and processes image data from various medical imaging examination equipment, transmits it to the physical examination information system, and generates physical examination reports with pictures and texts to meet the needs of high-level and efficient image processing in physical examination centers.
The digitization of images through the PACS/RIS system can further improve the economic benefits of the hospital, specifically as follows:
First of all , it improves the level of diagnosis and treatment in the hospital, speeds up the speed of diagnosis and treatment, reduces the waiting and detention time of patients, and improves the work efficiency of doctors and the use efficiency of equipment, which invisibly greatly improves the hospital's efficiency. Economic benefits;
Secondly , the digitization of images can reduce the costs of film manufacturing, purchase, use, and storage, and reduce the phenomenon of missed and lost films, which has obviously created objective economic benefits for hospitals to a large extent;
Third , it improves the reputation and attractiveness of the hospital and attracts more patients to the hospital for treatment, thereby promoting the hospital to further increase economic benefits, expand the hospital scale, and improve the overall level of the hospital.
1. Main functions of PACS system

3. PACS system - advanced precision algorithm for image processing
PACS can perform image processing on images with various algorithms, including smoothing, sharpening, noise reduction, edge extraction, grayscale equalization, image subtraction, image averaging, image fusion, tissue equalization, custom convolution kernel, and adaptive equalization. , contrast equalization, lumbar equalization, data analysis.
Advanced operations include some commonly used algorithms in medical image processing, such as:
smoothing: mild smoothing, moderate smoothing, high smoothing;
sharpening: mild sharpening, moderate sharpening, high sharpening;
noise reduction: mild smoothing Noise, moderate noise reduction, high noise reduction;
edge extraction: light extraction, moderate extraction, high extraction;
Patient statistics table: The department director can also make statistical summaries of patient cases in the department.
It is helpful to improve the accuracy and efficiency of diagnosis and facilitate the treatment of patients with similar cases; different statistical parameters can be set,
Statistical information can be set according to examination information, physician information, date range and other options.
Specifically, statistics can also be made based on inspection equipment and parts, etc.
Statistical reports can be printed directly for easy viewing.
Case statistics: Mainly based on different departments, different equipment, different doctors, different types, etc.
It is used to count the hospital's case status so that the hospital can dynamically manage the hospital's patient status.
4. Which departments of the hospital are covered by the PACS system?
1. Radiology Department: The Radiology Department mainly performs medical imaging work such as ordinary X-rays, computed tomography (CT), and magnetic resonance imaging (MRI) to provide diagnostic support for clinicians.
2. Pathology Department: The main task of the Pathology Department is to undertake pathological diagnosis during the medical process, including providing clear pathological diagnosis for clinical use and determining the cause of the disease through biopsy, exfoliation and fine needle aspiration cytology, and autopsy. Nature, ascertain the cause of death.
3. Endoscopy Department: The endoscopy room is an instrument mainly used by hospitals to observe certain
possible diseased parts of patients that cannot be directly seen by the human eye.
4. Ultrasound department: Ultrasound medicine is a young and important branch of medical imaging. Ultrasound examination
can be applied to various organs and results such as cardiovascular, abdomen, obstetrics and gynecology, small body organs and soft tissues, chest cavity, etc.
5. Interventional Department: Interventional radiology relies on the guidance of medical imaging equipment, uses puncture and catheter technology to
diagnose and treat diseases, and is a discipline that focuses on treatment.
6. Department of Nuclear Medicine: Department of Nuclear Medicine uses nuclear science and technology and methods to diagnose and treat diseases. It is
one of the main means of modern medicine. He has done some research on the imaging diagnosis of thyroid disease, tumors, coronary heart disease, kidney disease, etc. and
the treatment of hyperthyroidism and bone metastasis cancer, and has achieved good medical and social benefits.
