Clinical application of minimizing picture archiving and communication system

Objective: To investigate the use of the minimizing picture archiving and communication system (mini-PACS) in practical work and to realize the advent of filmless radiology. Methods: A PC-based ethernet was set up. The medical imaging equipments including CT, MR, digital fluoroscopy, DSA, and a laser camera were combined with the ethernet, and the digital imaging network (DIN) was integrated with the medical diagnostic imaging system (MDIS). In this way, the radiology information system (RIS) was established. Through one of the PC workstations with a double network card, this RIS was connected to the hospital information system (HIS). Results: The mini-PACS has been repeatedly used for more than 2 years. The system in Radiology department has been established and improved. With the present digital imaging system, such functions as the acquiring, storing, transmitting, printing, and browsing of digital images have been put into practice, all in accordance with the manners of the digital imaging communication in medicine 3.0 (DICOM 3.0). Digital imaging and diagnostic reports were managed through Microsoft Access database. Images may be kept on line in different kinds of equipment for 3-6 months. All images have been recorded on CD-R disks, so as to be kept off line permanently. So far, over 32700 reports have been stored in the database. From mini-PACS HIS terminals images and diagnostic information may be acquired on a limited scale. Conclusion: mini-PACS needs only a low cost of investment and operation. Its maintenance is simple and its performance is efficient. The main functions of the PACS can mostly be achieved. There lies a bright prospect for its use in small and medium hospitals
