6. 수도권에 인접하면서 가동병상수가 작은 병원들이 손익분기점을 이루는 촬영건수에 가장 많이 미달하였다.
이상과 같은 결과로 미루어 고가장비의 도입설치 계획시는 병상 규모 등의 외형적 조건으로만 의사결정을 할 것이 아니라 이미 도입 설치된 병원에서의 가동경험과 병원이 위치한 지역의 특성 등도 충분히 고려하여야 할 것이라고 생각된다.

Computed Tomography Scanner(CT) is highly expensive in operation as well as purchasing. That reason may cause not only to increase the burden of patients but also to waste the capital resources leading to financial difficulties.
However the numbers of CT install ed throughout the country is increasing, because of efficiency in medical care, patient's concern, competititons among the hospitals within the same area.
In the non-Metropolitan area the scanners were expexted to be less utilized and less profitable. Nine hospitals equipped with the CT were studied on the utilization of that equipment during the period from November 1984 to February 1985 in non-Metropolitan area and breakeven point in one hospital was analyzed for estimating profitabilities.
The results were as follows;
1. Among those nine hospitals, four hospitals had less than 400 beds, which is one of the restrictive minimum standards on the installation of Whole-body Computed Tomography Scanner.
2. The operating time during the normal operation period was longer than those of any other studies, but the accumulated down time was also longer than those of any other studies. The average number of scanning per week for each CT was 45, while the estimated number of for the break-even point was 56.7 cases.
3. When the downtime was excluded in calculating the average operation would be much closer to the cases for the break-even point. Therefore the break-down of the equipment was to be a main cause of the low profitability.
4. The average scanning rate for head area was 33.6%, however three of the nine hospitals showed about 20%.
5. If scanning ratio for the body parts excepting head was increased, the number of scanning for the breakeven point would be diminished.
6. the small size hospital especially located near the Metropolitan area showed largest loss in the CT operation. In purchasing the highly expensive equipments in hospitals, demand should be taken into account and planning is recommended.
