Abstract：Objective To reduce the occurence rate of failures, the maintenance experience was summarized through ananlyzing and
repairing the “no count” fault of SIENENS ECAMHD3R ECT probe. Methods Probe 1 and probe 2 on the collimator were measured
by point source test. Then fault points were found through multiple sets of tests after entering the local service mode of the machine.
Results After maintenance, it was found that the failure component was PI59R plate of probe 2, and the machine returned to normal
use after replacement. Conclusion The structure ECAMHD3R ECT probe was complicated, there were lots of difficult troubles.
Maintenance of ECAMHD3R ECT probe should be carried out based on detailed analyzing the operating principle of the equipment
and finding faults carefully.
