日本的计算机断层扫描（CT）系统数量约为OECD平均水平的4.3倍。然而，CT系统是昂贵的，因此，医院管理的沉重的财政负担。我们计算了日本引进CT的年净利润，包括单层CT（SSCT）、多层CT（MSCT）、医院床位数和都道府县。我们还分析了影响CT盈利能力的因素。首先，对2011年每个运营中的CT的年收入进行了估计。其次，每台CT的年成本计算为折旧、维护和人工成本的总和。最后，估计了SSCT和MSCT、医院床位数和地区的每台CT的年净利润。通过对各都道府县CT净利润与人口、每台CT设备医师数的相关性分析，确定了各都道府县CT净利润的决定因素。我们的研究结果表明，对于床位少于100张的医院，SSCT的年净CT利润高于MSCT，而对于床位至少为100张的医院，SSCT的年净CT利润高于MSCT。SSCT和MSCT的利润都随着医院床位数量的增加而增加。平均而言，每个州的CT年净利润为SSCT-12，105美元，MSCT为87，233美元。每县的年净利润和每CT的人口数与SSCT和MSCT呈正相关，每县的年净利润和每CT的医生数也呈正相关。因此，选择高性能MSCT在至少拥有100张床位的设施的盈利能力方面是有利的。此外，CT的盈利能力可能会影响引进CT的数量、每台CT的人口数量和每台CT的医生数量之间的平衡。
The number of computed tomography (CT) systems in operation in Japan is approximately 4.3 times higher than that of the OECD average. However, CT systems are expensive, and thus, a heavy financial burden for hospital management. We calculate the annual net profits from CT introduction in Japan for single-slice CT (SSCT), multi-slice CT (MSCT), number of hospital beds, and prefecture. We also analyze the factors that affect CT profitability. First, the annual income per CT in operation is estimated for 2011. Second, the annual costs per CT are calculated as the sum of depreciation, maintenance, and labor costs. Finally, the annual net profits per CT are estimated for SSCT and MSCT, the number of hospital beds, and prefecture. A correlation analysis between the annual net profits, population, and number of physicians per CT equipment is used to determine the determinants of the net CT profits by prefecture. Our results show that, for hospitals with fewer than 100 beds, the annual net CT profits are higher for SSCT than MSCT, and vice versa for hospitals with at least 100 beds. Both SSCT and MSCT increased profits as the number of hospital beds increased. The annual net CT profits per prefecture are USD -12,105 for SSCT and USD 87,233 for MSCT, on average. The annual net profits per prefecture and population per CT show positive correlations with both SSCT and MSCT, as do the annual net profits per prefecture and number of physicians per CT. Thus, choosing high-performance MSCT is advantageous in terms of profitability in facilities with at least 100 beds. Additionally, CT profitability presumably affects the balance between the number of introduced CTs, population per CT, and number of physicians per CT.
