Gather Load Data Test Results Show Inconsistent MultiCoil Bias Current Channel-to-Channel.

Gather Load Data Test Results Show Inconsistent MultiCoil Bias Current Channel-to-Channel See Long Description The "Gather Load Data" diagnostic was run on a working 1.5T Excite HD system with the 1.5T 8Ch TR Knee Array, p/n 5114356-2, (coil name HD TRKnee PA) on 12.0 M4 software to check the coil operation after this coil was replaced. The new coil is working fine for the customer but the FE is puzzled as to why the MultiCoil Bias open circuit test current shown in the test results is inconsistent channel-to-channel. Shouldn't each of the eight coil elements have about the same bias current reported in this test? Also on some of the coil elements, the current reported by Gather Load Data is below the minimum of 98 mA . Why then doesn't the system fault for this problem in patient scanning? We would expect the system to fault during patient scanning with current below the minimum open circuit current. Similar data is seen when plugging the coil into either the "A" or "B" LPCA coil ports. To check the system, the FE tried the same test using a different type of HD 8-channel coil and the Gather Load Data test results showed consistent MultiCoil Bias open circuit current for all eight channels. What is happening here? Is the system okay? Is there a problem with this coil? See below for "Gather Load Data" MultiCoil Bias test results taken from this site with the coil plugged into the "A" LPCA coil port (Open_17 through Open_24). Note: When plugging the coil into the "B" port, the data is seen in Open_25 through Open_32). more /usr/g/service/log/Default_mc.txt [Enter] Channel Num, mA1, mA2, mA3, mA4, mA5 Short_ 1, -129, -128, -129, -126, -129 Short_ 2, -129, -129, -129, -129, -129 Short_ 3, -128, -128, -128, -128, -128 Short_ 4, -131, -131, -129, -129, -129 Short_ 5, -129, -125, -129, -129, -129 Short_ 6, -132, -132, -132, -137, -131 Short_ 7, -132, -131, -129, -131, -132 Short_ 8, -132, -132, -132, -132, -131 Short_ 9, 3, 3, 3, 3, 2 Short_10, 3, 3, 3, 3, 5 Short_11, 3, 3, 3, 5, 3 Short_12, 3, 5, 3, 5, 5 Short_13, 5, 3, 3, 5, 3 Short_14, 3, 5, 3, 3, 3 Short_15, 2, 0, 0, 2, 0 Short_16, 0, 2, 2, 2, 2 Short_17, 5, 5, 5, 5, 5 Short_18, 2, 3, 3, 3, 2 Short_19, 5, 5, 5, 5, 5 Short_20, 8, 3, 3, 6, 3 Short_21, 2, 10, 10, 2, 10 Short_22, 5, 5, 5, 5, 5 Short_23, 6, 5, 5, 6, 5 Short_24, 5, 5, 5, 5, 5 Short_25, 5, 5, 5, 5, 5 Short_26, 6, 6, 6, 6, 6 Short_27, 2, 2, 2, 2, 2 Short_28, 3, 3, 3, 3, 3 Short_29, 3, 3, 3, 3, 3 Short_30, 2, 2, 2, 2, 2 Short_31, 3, 3, 3, 3, 2 Short_32, 2, 2, 2, 2, 3 Open_ 1, 163, 162, 163, 163, 162 Open_ 2, 163, 163, 163, 163, 163 Open_ 3, 166, 166, 166, 166, 166 Open_ 4, 163, 164, 164, 164, 164 Open_ 5, 166, 166, 166, 166, 166 Open_ 6, 164, 164, 164, 163, 164 Open_ 7, 164, 163, 164, 164, 163 Open_ 8, 162, 162, 162, 162, 162 Open_ 9, 3, 2, 3, 3, 3 Open_10, 3, 3, 3, 2, 3 Open_11, 3, 2, 3, 3, 0 Open_12, 3, 5, 3, 3, 5 Open_13, 5, 3, 5, 5, 3 Open_14, 3, 5, 3, 3, 5 Open_15, 2, 2, 2, 2, 2 Open_16, 2, 3, 3, 2, 2 Open_17, 78, 78, 78, 78, 78 Open_18, 101, 98, 100, 98, 98 Open_19, 395, 395, 393, 393, 392 Open_20, 390, 390, 389, 389, 389 Open_21, 311, 311, 311, 310, 310 Open_22, 98, 98, 98, 98, 98 Open_23, 79, 79, 79, 79, 79 Open_24, 310, 310, 310, 310, 310 Open_25, 3, 3, 3, 3, 3 Open_26, 5, 5, 3, 3, 3 Open_27, 0, 0, 0, 0, 0 Open_28, 2, 2, 2, 2, 2 Open_29, 2, 2, 2, 2, 6 Open_30, 0, 0, 0, 0, 0 Open_31, 2, 0, 2, 2, 0 Open_32, 2, 2, 2, 0, 2
