HIGH-RESOLUTION CONTACT MICRORADIOGRAPHY WITH ULTRASOFT POLYCHROMATIC X-RAYS.
Abstract
The purpose is to discuss the practical methods that have been employed to achieve high-resolution microradiograms of biological specimens by using polychromatic X radiation. Factors influencing microradiographic resolution are given: recording emulsion; and the geometric relationships (emulsion thickness, section thickness, and sample-emulsion 'interspace' distance. The X-ray apparatus used for making the contact (unit magnification) microradiograms is described.
