1 故障现象在 T1 序列扫描过程中经常出现扫描中断或在扫描结束时出现噪声图像 ,计算机当前状况显示 RFPA(射频功放 )差错 ;T2 序列扫描正常。2 故障分析排除系统故障诊断报告显示 :RFPA没有工作或工作在线性范围之外 ,要求重新装入序列 ,参数再执行。根据报告上要求重新执行
1 Fault phenomenon Scanning interruption or noise image appears at the end of the scan during the T1 sequence scan. The current status of the computer shows RFPA (radio frequency amplifier) errors. The T2 sequence scan is normal. 2 Fault Analysis Troubleshooting The system fault diagnosis report shows that the RFPA is not working or working outside the linear range. It is required to reload the sequence and parameters are executed again. According to the report to re-execute
