Abstract: An X-ray diagnostic installation includes an X-ray source and a radiation receiver and a digital imaging processing system, the digital imaging processing system including a computer which evaluates an X-ray image of a phantom by identifying visible details in the X-ray image of the phantom. The computer employs these identified visible details to automatically construct a contrast-detail graph of the phantom. The computer thus undertakes an automatic judgment of the imaging quality, without the need for a trained observer.
