Flash X-ray Techniques for Biomedical Radiography

抄録

Flash x-ray (FX) generators for biomedical radiography and their applications are described. The FX generators may be generally used for condenser charging voltages of 50 to 100kV, and peak currents of more than lOkA. The exposure times of the FX were about ips. The FX intensity and quality were primarily determined by controlling the condenser charging voltage, the anode-cathode (A-C) space, and insertion of metal filters. The effective focal spot varied according to the anode and cathode electrode combinations and the insertion of metal filters. The serial exposure type of FX generators could produce high intensity FX having variable photon energies and time intervals. The FX generators have many future possibilities for performing biomedical radiography utilizing their high speed capabilities.
