A scheme for extracting and comparing graphs from medical reports to detect duplicates that may indicate fraudulent medical diagnostic testing results, due, e.g., to billing or insurance fraud. Domain knowledge is used to pre-process input documents and automatically extract graph images. These images are stored in a database and compared to one other using a distance-based comparison metric that is robust to noise and other image acquisition artifacts. Graphs are compared in blocks of 1000 images at a time using a two-pass comparison algorithm to identify the top matches for each graph. If a graph on the page currently being analyzed is identified as a close enough match to a known graph in the database (e.g., the graph extracted from the current patient's medical record appears to be identical to the graph of a different patient), then the page is flagged as potentially being evidence of fraudulent activity.

A portable system for substantially automated monitoring of nerve conduction velocity through the carpal tunnel of a patient includes an electrode supporting structure which supports stimulating and pickup electrodes in a predetermined spatial relationship so as to contact the patient's arm and hand. The electrode supporting structure is a part of a housing which contains stimulating signal generating and response signal processing circuitry, which operates substantially automatically under control of a microprocessor. The microprocessor controls generation of stimulating pulses and determines the elapsed time until the occurrence of a predetermined response signal characteristic, such as its peak. Data relating to nerve conduction time or velocity measurements and response signal waveform are stored in a removable memory to permit later analysis and treatment recommendation by a physician. The system is useful for screening large groups of people at remote locations, such as workers at an employer's facilities, for evaluating their median nerve condition and likelihood of developing carpal tunnel syndrome.
