Cavity anomaly detection device

Abstract

An apparatus may detect an anomaly in a cavity in an object. The apparatus may comprise an array, a signal processor, and a threshold excedent determination processor. The array may receive an intensity reduced transmission beam of energy resulting from an irradiating beam of energy passing through an object having a cavity and a cavity wall. The cavity may be defined by the cavity wall. The array may have sensors. The signal processor may receive a measurement of the intensity reduced transmission beam; determine a thickness of the cavity wall; estimate an absorption rate of cavity wall; compute a predicted measurement employing the thickness and absorption rate; and calculate a cavity anomaly statistic for a cavity anomaly employing the predicted measurement and the measurement. The threshold excedent determination processor may generate a notification when the cavity anomaly statistic exceeds a threshold.
