I HAVE A PROBLEM WITH GE LUNAR DENSITOMETRY CALIBRATION FAILURE, IT FAILS ON THE SPILLOVERS BECAUSE THE VALUE OVER 12%, DOES ANY BODY HAS SERVICE MANUALS OR A TROULESHOOTING OR HOW TO CORRECT THIS PROBLEM.... THANX ANYONE CAN REPLY THIS
Spillover
An increase in the Spillover percentage over time is an indication that the PMT is losing
resolution, even if the Spillover test does not fail. Trends in excess of those specified on in
section 8.15 indicate service is required. A large change in the Spillover can be explained in
some cases by standard positioning (or a small change in the home position of the scanner). If
the beam is not fully eclipsed by the brass piece during the Spillover test, the Spillover value
increases dramatically
hi,
verify first the alignment of the tube with the detector in "alignment aid". Second, verify detector-detectors depending on what model you have (dpx or prodigy series). Verify the cerum filter between tube and colimator.
Best regards,
Victor

Is this a DPX? Have the CV, and SD values changed? If not it could also be your collimator, or lead shavings under the shutter.
