| titleOfInvention | Real-time digital x-ray subtraction imaging |
| abstract | ABSTRACT Different images, derived from an X-ray image of an anatomical sub-ject, are produced in real time by directing X-rays through an anatomical subject to produce an X-ray image, converting the X-ray image into a series of television fields comprising trains of analog video signals, converting the analog video signals into corresponding digital video signals, integrat-ing the digital video signals over a series of successive time intervals corresponding with a plurality of televisoon fields and thereby producing a series of sets of integrated digital video signals, performing a series of subtractions between each set of integrated video signals and the preceding set of integrated video signals and thereby producing a series of successive digital difference video signals, converting the digital difference video signals into analog difference video signals, and converting the analog dif-ference video signals into a series of visible television difference images representing changes in the X-ray image between the successive time intervals. Apparatus for carrying out this method is also disclosed. |
