Paper Abstract

Radiographic signal detection is considered to be a point process. Realism of radio-graphic signal detection experiments is extended by allowing a random number of signals and by requiring accurate location of the signals. A substantial improvement in the simplicity of the theoretical framework of multiple signal detection experiments results from using this free response approach. The generation of false positive events is adequately described as a Poisson process, represented by a single measurable parameter. A scheme for reinterpretation of earlier conventional Receiver Operating Characteristic (ROC) curves in terms of the free response approach is presented, and a description of a much simpler and more efficient experimental procedure is provided.
