Vertical band artifacts on LAVA series using the 8ch body array coil due to bent pins on connector 2417162.
Symptom
MRIQ: Dark Vertical Bands or Venetian Blind Artifact in Images See attached file. The system is a 1.5T HiSpeed, with SGD Gradients, running 9.1 M4 software. These artifacts were pretty repeatable. The problem appeared to only occur on the Knee scans and some scans done with the TORSO coil. The Customer would see an artifact just about every other patient scan. There were intermittent errors in the log stating X axis overload and PPBM errors. See attached file. The system is a 1.5T HiSpeed, with SGD Gradients, running 9.1 M4 software.
