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.
