目的：对Ｉｍａｔｒｏｎ电子束成像系统（ＥＢＩＳ）的购买、安装、维修和运作成本进行评估，并与常规ＣＴ同样的成本作对比。材料和方法：分析Ｂｒｏｕｓｓａｉｓ医院ＥＢＩＳ和巴黎其他公立医院常规ＣＴ的购买、安装、维修保养及运作支出清单，并对二者进行比较。结果：ＥＢＩＳ的购买及安装费用为１５，０００，０００ＦＦ，每年的维修保养支出为其机器价格的９．５％，即９５０，０００ＦＦ（其中包括调换电子枪及靶的费用）。由于更换球管较频繁，故常规ＣＴ每年的维修保养费用为其售价的２１％。折算成每次扫描的成本，ＥＢＩＳ为４．７５ＦＦ，而常规ＣＴ为７．８８ＦＦ，熟悉机器运作及善于排除高压电源故障以后，ＥＢＩＳ的停机率为２．１８％（不包括保养时间）。结论：购买ＩｍａｔｒｏｎＥＢＩＳ花费较高，但其运作及维修保养费用则较低，由此看来，就成本而论ＥＢＩＳ对常规ＣＴ是具有竞争力的。
Purpose: To evaluate the cost of purchasing, installing, repairing and operating the Imatron Electron Beam Imaging System (EBIS) and compare it with the same cost of a conventional CT. Materials and Methods: To analyze and compare the purchase, installation, maintenance, and operational expenses of EBIS at Broussais Hospital and other public hospitals in Paris. Results: The EBIS was purchased and installed at 15,000,000FF and the annual maintenance charge was 9.5% of its machine price, or 950,000FF, including the cost of switching electron guns and targets. Due to the replacement of the tube is more frequent, so the regular CT annual maintenance costs of 21% of its selling price. EBIS was 4.75FF for EBIS, compared to 7.88FF for conventional CT. After familiarizing with the operation of the machine and being able to troubleshoot high-voltage power failures, the EBIS downtime was 2.18% (excluding maintenance). Conclusion: EBIS is cost-effective to conventional CT in terms of cost, as the cost of purchasing Imatron EBIS is higher but its operating and maintenance costs are lower.
