1. A method for detecting a presence of aberrations within a workpiece having internal walls that define an internal conduit of the workpiece, the method comprising:

  • delivering fluid through the conduit;

    equalizing the temperature of the workpiece with the temperature of the fluid and maintaining the temperature of the workpiece and the fluid in a steady state condition;

    measuring one or more conditions of the fluid as it traverses at least a portion of the conduit;

    mechanically exciting the workpiece causing an excitement event; and

    identifying whether an aberration is present within conduit or conduit walls based on the one or more measured conditions of the fluid,providing a processor having inputs for receiving electronic data reflective of the temperature condition of the fluid and the excitement condition of workpiece, and wherein the identifying step further includes;

    correlating any changes in the temperature condition of the fluid data with the excitement event.
