X-ray diagnostic apparatus comprising means for the enlarged visual display of a selectable detail of the overall image
First Claim
1. An X-ray diagnostic apparatus, comprising:
- an X-ray source, first imaging means for forming an image of the intensity distribution of X-rays directed through a test object, first and second image sensors, optical imaging means for imaging an overall image presented by the first imaging means onto the entrance surface of said first image sensor, display means for visual display of the overall image means for enlarging the visual display of a selectable detail of the overall image and means for directing at least a portion of the overall image onto said second imaging sensor which exhibits a substantially higher number of pixels with respect to the unit of surface area of the overall image than said first sensor.

Abstract
An X-ray diagnostic apparatus, comprises an X-ray source (1), an imaging surface (6) on which the intensity distribution of the X-rays to be applied to a test object (4) is imaged, an optical imaging device for imaging an overall image (10) of the imaging surface (6) onto the entrance surface of a first image sensor (11), a device (12) for the visual display of the overall image (10), and an imaging enlargement device for the enlarged visual display of a selectable detail of the overall image. Strongly enlarged and still high-resolution detail images are generated in that the selectable detail (20) of the overall image is directed onto a second image sensor 16) which discriminates a substantially higher number of pixels relative to the unit of surface area of the overall image.
