Medical viewing system for displaying an X-ray image

摘要

A medical viewing system comprises an X-ray source, a collimator for limiting the X-ray radiation output of the X-ray source and a flat X-ray detector, wherein the collimator is adjustable such that the subsequent X-ray images acquired by the X-ray detector comprise a rectangular shape with variably rounded corners. The acquired X-ray images have a shape, which is in-between a circular shape and a rectangular or square shape. Acquired images with this shape may then be displayed on a display unit, wherein the borders or the images are distant from the borders of the designated screen area of the display unit in order to define a gap on the display. On rotation of an acquired image the rounded corners move towards the borders of the screen and are dimensioned such that they never cross the borders of the display. The used area of the screen 30 is approximately 30% larger than that of a circular image, e.g. taken by means of an image intensifier.

主权项

1. A medical viewing system, comprising:
an X-ray image acquisition device comprising a flat X-ray detector and an X-ray source, said source comprising a collimator; a display unit; and a calculation unit connected to said X-ray image acquisition device and said display unit, said collimator being adjustable such as to cause an X-ray image acquired by the X-ray detector from X-ray radiation collimated by said collimator to have a rectangular shape with rounded corners, the rounding being variable in accordance with the adjustment, wherein the calculation unit is configured for displaying the acquired image on the display unit, and by said displaying enclosing a variable gap between the borders of the image and the borders of the display unit such that the image is rotatable without intersecting the borders of the display unit.
