How would you service a beam former issue—indicated by "shooting steaks" and lines in the image plane—without having the field service dongle to access on board diagnostics? We have a service contract, so the FSE is performing the work. Is this work that can be performed without use of those diagnostics tools? I have 11 years of biomed experience with seven years of support to the ultrasound modalities in my hospital—emphasis on Siemens’ Sequoias and Anteres—no training, but hard knocks on the GE line.

In most cases, beam-former failures can be diagnosed without the need for diagnostic utilities. The technique might be different based on the system model. For example, a Sequoia 512 has two beam-former (BF) boards. They are interchangeable, so moving them will cause the problem to move from one side of the image to the other, confirming the BF board is defective. For Voluson 730 systems, the CPR board (beam-former) is the cause for the “shooting streaks.” Replacing this board does not require a service dongle.
