ABSTRACT: Medical diagnostic tables are widely used inthemedical
diagnostic equipment. For multifarious diagnostic needs, the medical diagnostic
table works in various operating modes. In order to ensure patient safety,
safety factor of medical diagnostic table must meet safety requirement. The
paper puts forward a method to find relations between key parameters and stress
of table, identify maximum stress modes, reduce modes number of load test, and
remove conservative high stress areas from finite element analysis result, by
synthesizingthestress result of finite element analysis and measurement data for
various operating modes of medical diagnostic table. It will help shorten test
time, avoid over strength design, and reduce table’s cost. An application
example of the method is presented by evaluating a specific CT medical
diagnostictable. This method can be a reference for safety evaluation of all
medical diagnostic tables.
