High resolution microradiography with ultrasoft X-rays

Abstract

A small compact microradiographic unit for microradiography with ultrasoft X-ray has been developed. The equipment is simple in operation and yields microradiograms with a linear resolution of about ¼ of a micron. The microradiograms recorded with soft and ultrasoft X-rays will show the distribution of dry weight in soft biological material, and also the distribution of water. The procedure of quantitative microradiography gives the possibility of obtaining accurate information about the parameters mentioned, and with an analytical error of only a few to ten per cent.
