The Los Angeles X-Ray Survey Film and Record Library, Its Past Development, Present Activities and Future Possibilities

SUMMARY Tuberculosis had represented a tremendous drain on local governmental agencies, as well as upon the people who support them. The recent decline in tuberculosis morbidity and mortality rates have already greatly lightened the relative burden to the tax-payers from this disease. For some years, however, the continuance of unrecognized cases in the population constitutes a constant menace of the renewed spread of the disease. Maintenance of the X-Ray Survey Film and Record Library constitutes a substantial contribution to the maintenance of the control and the further studies which may accelerate the disappearance of tuberculosis. The utilization of the x-ray film survey in the investigation and control of cancer, heart disease and other conditions detected by chest surveys may then be contemplated.
