Abstract
The disclosure proceeds from the fact that, even in the case of the most painstaking selection of the hardness of X-rays employed for the purpose of irradiation of heterogenously composed specimens, such as, for example, body parts interspersed with bones, no video image which is entirely satisfactory in all parts is obtained. An image is desirable in which the fine contrasts of soft parts appear just as clearly as those of parts which, such as bones, for example, strongly absorb X-rays. To this end the disclosure provides that image signals, which are generated with X-rays of various hardnesses; for example, such of more than 100 kV and such of less than 60 kV, be stored, and that therefrom the respectively favorably represented surface elements be joined together to form a resultant image. The disclosed embodiment is particularly suited for use in medical X-ray diagnostics.
