repaired probes could suffer from poor performance in the elevation plane

Hi,

I am aware that repaired probes could suffer from poor performance in the elevation plane, even though the probe passes the uniformity test. Elevational side lobes reduce the contrast in the image. I do not know how widespread is the use of such probes.  Has anyone made a study looking across probes in the same department where many of the same type of probe are in use? If so, have you noticed any difference in  the contrast?

Probe repairers may be unaware of such defects when relying upon the Uniformity test alone. Has anyone asked the repairer how they test for changes in elevation side lobes following repair? Given the outcome of the case in the USA, link below, should we continue to carry out such repairs and where does the buck stop when litigation hits the fan? With the repairer, or the hospital for not carrying out adequate tests following repair.
