This research examined use rate and profitability of equipment in hospital scale with about 500 beds to present data including to review before introducing PACS with the checklist included in preparation and proposal based on expected profit suggested by operation department and cost and use rate of the expensive medical equipment were analyzed. It was proved that profit was generated in the research subject hospital if PACS is introduced. Three to five year of lease is proper for the purchase method of medical equipment. Profit after two year of use will surpass investment cost and generate clear profit. Based on the profit generated from operation of radiology department, the purchase amount to introduce PACS at the hospital will be retrieved after about 1.9 years for the investment. The number of reshoot test at radiology department will be decreased and film, development, and fixer will not be necessary to buy so the operation cost will be reduced. Moreover, other than actual profit increased, the hospital can improve its reputation and employees can reduce their works and get better working environment with less stress. Their job satisfaction will be increased so they can improve service quality and it is good for marketing strategy of the hospital. As a result of this research, it was proved that the small and general hospital should have expected profit with introduction of PACS and analyze its contribution to treatment service and profit after the purchase. Then, the hospital should make a proposal for introduction of the medical equipment and establish effective operation plan.

외부 데이터가 진료병원 Server에 저장됨에 있어서 판독을 의뢰하지 않을 경우, 대부분의 병원이 무상으로 이루어 지고 있는 상황이며 이에 외부 데이터 단순 import의 효율적인 관리를 위한 수가 적용 여부를 검토하였다. 2007년 3월부터 4월까지 서울 경기 지역의 PACS가 도입 된지 1년 이상, 병상 수 500Bed 이상의 종합 대학병원 25곳에 근무하는 각 병원의 PACS 운영실 및 PACS 관리자를 대상으로 하였다. 외부 데이터에 관한 10가지 항목의 설문지를 작성하여 각 병원의 PASC 담당자 및 관리자를 대상으로 E-mail을 이용한 자기 기입 방식, 전화를 통한 질의응답 방식으로 조사하였다. 조사된 25개의 종합 대학병원의 96%이상이 외부 데이터 단순 import를 지원하고 있었으며, 그 중 92%의 병원은 무상으로 이루어지고 있었다. 이와 같이 진행 되는 부분에 대하여 각 병원의 PACS 담당자 70% 이상이 단순 import에 대한 수가 적용의 필요성을 느끼고 있으며, 현재 많은 병원에서 단순 import의 무상 지원으로 인한 문제점을 인식하고 있었다. K병원을 기준으로 단순 import에 년간 H/W 소요 비용은 336만원이고, 년간 인건비 소요비용은 421만원이다. 또한 단순 import 한 건당 평균 데이터 size는 48MB 정도로 조사되었다. 환자 입장에서 진료에 참고자료로 사용 될 외부 데이터의 정확한 저장과 정당한 PACS 사용을 위해서는 그에 상응하는 수가가 적용 되어야 할 것이다. 보험심사평가원 급여기준에 따라 수가적용이 인정되어 의료영상 디지털화로 인한 초기의 고액 투자비용 보장과 회수를 위해 단순 Import의 수가 적용이 반드시 필요하다고 사료 된다.

Picture archiving and communications systems(PACS) for digital image distribution, archiving and transmission, represent the modern hospital. PACS is the medical image management system within a hospital, whereas teleradiology system is the medical image communication system between remote sites. PACS and teleradiology systems usually consists of mainly four parts such as image acquisition part, image storage and database part, Image communication network part, and image display workstation part. Among these components comprised In the PACS, workstations are the point of contact between a PACS and the radiologist or referring physician. Therefore, the acceptance of PACS is highly dependent on workstation functionality, performance and easy of use compared with the conventional film-based radiology. This paper describes overall configurations and some requirements of PACS and teleradiology.

This study was conducted to improve performance flow of PACS registration and output of external medical images by developing or adding File Transfer Protocol(FTP) Module on Order Communication System(OCS) and to upgrade efficiency of performance. The numbers of requests for examination of external medical images from January 2004 to December 2007 were investigated and the numbers of cases of examinations and losses were done respectively from January to June, 2007 as a period before the improvement and from July to December, 2007 as a period after it. Satisfaction of persons inputting external medical images of CD was asked directly before and after the improvement. When the numbers of requests for examination of external medical images from 2004 to 2007 2004 were investigated, they were 12,783, 16,774, 21,613 and 27,487 cases in 2004, 2005, 2005 and 2007 respectively. For the numbers of the requests from January to December, 2007 it was the lowest in February by recording 1846 and it was 2800 in October. While the number of loss of external medical images was averagely 3.6 before using FTP Module on OCS, it reduced to 0 and satisfaction increased to 98% after it. By utilizing FTP Module on OSC for PACS registration of external medical images, the images were delivered simultaneously with occurrence of order, PACS registration of many patients was conducted together and CDs were returned to patients immediately after sending images from outpatient clinics or wards to remove possibility of losing them. In addition, because the module was established on OCS and data were sent associated with order, problems related with order were decreased. By eliminating movement distance it was turned out to be very effective in terms of time and space.

Filmless full-PACS in korea has rapidly been growing, since government had supported collaborative PACS project between industry and university hospital in late of 1995. At the same time, a small company had started PACS business, while the Korea PACS society was being formed. In the beginning, PACS societies had focused on developing peripheral solutions such as DICOM gateway for image acquisition, x-ray film digitizer, and viewing software for research or management of personal image data, while Samsung Medical Center had started installing an imported partial PACS system which had recently upgraded with a new system. In similar time frame, a few hospitals had started developing and installing domestic large scale full-PACS system. Several years later, many hospitals have installed full-PACS system with national policy of reimbursement for PACS exams in November 1999. It is believed that Korea is the first country that adopted PACS reimbursement for filmless full-PACS as a national policy. Both experiences of full-PACS installation and national policy generated tremendous intellectual and technological expertise about PACS at all levels, clinical, hospital management, education, and industrial sectors. There are currently three types of PACS system which includes domestic, imported, and hybrid PACS system with imported solution for core system and domestic solution for peripheral system. There are more than 20 domestic PACS companies and they have now enough experiences so that they are capable of installing a truly full-PACS system for large-scale teaching hospitals. PACS societies in Korea understand how to design, implement, install, manage, sustain, and provide good services for large-scale full-PACS. PACS society has also strength for the highest integration technology of the Hospital Information. However, further understanding and timely implementation of continuously evolving international standard and integrated healthcare enterprise concepts may be necessary for international leading of PACS technologies for the future.

One of current trends of medical technology is analog to digital. Moreover, The Government put a premium on PACS(Picture Archiving and Communication System) for Medical Insurance in November, 1999. Therefore many hospitals are installing(or planning to install) PACS facilities on their buildings. However most of hospitals didn't consider PACS facilities in the beginning of construction. In particular, the Networking is one of the most difficult things for PACS installation. There is no space for network equipments, and no path for network lines, etc. To solve these problems, wireless network is proposed. The wireless network is divided to three parts mainly. One is the wireless communication for Local Area Network, another is the data transmission through a satellite for Tele-Radiology, and the last one is the technology using Bluetooth for each sub-system of PACS. But there are other problems in wireless systems, i.e., network bandwidth, system stability, interference with other devices. The purpose of this paper is to suggest the future and new trend of PACS including all the problems.
