Abstract
Described is a radiation sensitive imaging film containing a heat fixable radiation sensitive element, e.g., a diacetylene, of the formula: R--C.tbd.C--C.tbd.C--R', where R and R' are, e.g., both --CH.sub.2 --O--CONH--(CH.sub.2).sub.5 CH.sub.3. After exposure to X-radiation during diagnostic or X-ray therapy, the resulting image can be permanently dry fixed by a short heating step and then stored for a long period. Processes for making the film, new binder-convertor systems, and a device incorporating the film are described as well as other imaging, diagnostic and therapeutic methods utilizing the film in high energy radiation applications in the health care field.
