<p style="">PHILIPS Achieva3.0T磁共振作为目前业内最完美的通用性磁共振系统,具有强大的功能,能够快捷、准确、高质量地完成各种类型的临床检查;其互动功能使检查更加高效、快捷,图像更加清晰、准确;革命性的SENSE高速并行采集技术[1]更被广泛认为是影像事业发展史上的里程碑。本机的运行成本(主要是Philips公司的维修保养费用)非常高,3.0T MR已成为医院诊疗过程中不可缺少的大型医疗设备,如何在保证设备正常运行的情况下,把运行成本降低?如何保证设备效益的最大化也是医院关注的主要日常工作之一。本文将2010.03-2012.08设备应用期间,设备运行稳定性与维修保养相关费用进行分析,探讨设备效益的最大化。</p><p style=""> 2.系统结构</p><p style=""> PHILIPS 3.0T磁共振主要由以下几部分组成:电源柜、磁体系统、梯度系统、射频系统、计算机和图像处理系统、线圈及附属设备等组成,附属设备包括空调机组、水冷机组、工作站、高压注射器,稳压电源、UPS、激光相机等。这些系统之间通过控制线、数据线及接口电路连接成一个完整的成像系统[1]。</p><p style=""> 3.材料和方法</p><p style=""> 3.1材料 PHILIPS 3.0T磁共振;水冷机组,空调机组;高压注射器、激光相机和工作站;2010.03-2012.8使用期间的故障维修记录。</p><p style=""> 3.2方法</p><p style=""> 3.2.1 以2010.03-2012.08 3.0T MR维修记录为准。</p><p style=""> 3.2.2 维修费计算 保修期内以PHILIPS公司最低报价为准,自行维修以实际发生的正规发票为准。</p><p style=""> 3.2.3用表格对设备故障部位、停机时间等与维修费用进行分类统计分析[2](见表1)。</p><p style=""><br /></p><p><img data-s="300,640" data-type="jpeg" src="http://mmbiz.qpic.cn/mmbiz/A1DicCH9Vl6OTbN1lN9smibJLT0sNvPL4zWfYyWqpaFhdzNG1iawuXTzwb2WBQGDicSicIqcmYiaE0FeK2PFhcjbuPDw/0" style="white-space: normal;" data-ratio="0.29446640316205536" data-w="506" /></p><p><br /></p><p style="padding: 0px; margin-top: 0px; margin-bottom: 10px; list-style: none; line-height: 1.5em;"> 由表1可知,在保修期内(2010.03-2011.03),出现问题较多,达40次,梯度柜维修一次,更换一次,停机3天,公司标价很高;射频系统更换CPU Module板2块,维修该板一块,仅停机 1天;冷头故障一次,更换冷头一个;空调系统故障7次,冲氟补漏3次,压缩机损坏,更换压缩机一台,停机3天;水 冷机组故障21次,停机7天;主机计算机软件故障2次,分别通过修复程序[3]和重装软件修复,停机1天,因空调和水冷机组故障致液氦指示到66%,保修结束前补液氦到95%,停机1天。按照PHILIPS公司最低价,一年仅配件费就达210万元。自行维护维修一年(2011.03-2012.03),故障达46次,其中,射频系统CPU Module板损坏,因报价达5万美元,我们通过维修该板,使设备恢复正常,所有费用合计3万元人民币,修板期间,通过调整系统内部参数[4],使图像质量轻微降低,但没影响正常工作,板子修复后,恢复系统原来的参数;膝关节线圈损坏2次,自行修复,加工配件费用150元,头颈线圈损坏4次,购买材料和配件费用1860元,因有两个头颈线圈,没影响工作;空调机组损坏8次,冲氟补漏更换管道及过滤网,费用2800元;水冷机组损坏26次,更换配件(膨胀阀,冲氟)3800元,停机1天;高压注射器光纤损坏1次,更换光纤费用3600元。其它维修停机1天。</p><p style="padding: 0px;
