Abstract
Photothermographic systems have not been useful in combination with X-ray purposes because of low speed, poor resolution and poor contrast. A particularly designed photothermographic element in combination with a rare-earth intensifying screen provides a high quality, fast, high resolution photothermographic radiographic system.
