Abstract
A radiological system includes an image pick-up chain which includes an image processor having at an N-output, at which images having a number of lines which is standard, and an H-output for an H-image having a higher number of lines than the standard image. A video recorder is connectable to the N-output, an H-image playback unit is connectable to the H-output. The video recorder is in the image transmission chain, and has an output connected through an up-scan standards converter to a switch, by means of which the H-image playback unit can be connected to an output of the up-scan standards converter.
Claims11
A radiological system comprising:
- image pick-up means for acquiring an optical image, corresponding to a radiological image, of an examination subject;
- image processing means for converting said optical image in a single video chain into a normal image having a standard number of lines, supplied at a first output of said video chain, or into an image having a higher number of image lines than said normal image, supplied at a second output of said video chain;
- a video recorder connectable to said first output;
- playback means for displaying said image having a higher number of lines;
- an up-scan standards converter in video chain of said image processing means connected to an output of said video recorder;
- and
- switch means in said image processing means, connected to an output of said up-scan standards converter and to said playback means for supplying an image from said video recorder to said playback means through said up-scan standards converter.
A radiological system as claimed in claim I wherein said image processing means comprises digital image processing means.
