Abstract

An acquisition window for a medical apparatus (in particular for a computer tomography apparatus) has an element made of a suitable material and at least one attachment element for attachment to the medical apparatus.

First claim

We claim as our invention:

1. An acquisition window for a medical apparatus comprising an x-ray source and an apparatus housing in which the x-ray source is situated, said acquisition window comprising:
a window element comprised of x-ray-permeable material, said window element comprising a plurality of window sides; and
at least one attachment element that releasably attaches at least one of said sides of said window element to said housing of said medical apparatus.

2. An acquisition window as claimed in claim 1 wherein said at least one attachment element is configured as a hook.

3. An acquisition window as claimed in claim 1 wherein at least one attachment element comprises a male part and a mating female part forming a snack fit connection of said at least one side of said window element to said apparatus housing.

4. An acquisition window as claimed in claim 3 wherein said snap fit connection is selected from the group consisting of snap fit ring connections and snap fit ball connections.

5. An acquisition window as claimed in claim 1 comprising at least two attachment elements respectively attaching at least two of said window sides to said apparatus housing.

6. An acquisition window as claimed in claim 1 comprising a plurality of said releasable attachment elements, said plurality of releasable attachment elements being spatially distributed along said at least one window side in a distribution that equally distributes, among individual attachment elements in said plurality of attachment elements, a total force applied by said plurality of attachment elements to attach said at least one window side to said apparatus housing.

7. An acquisition window as claimed in claim 1 wherein said at least one attachment element is directly attached to said x-ray permeable material of said window element.

8. An acquisition window as claimed in claim 1 comprising frame that surrounds said window element and that is attached to the x-ray permeable material of said window element.

9. An acquisition window as claimed in claim 8 wherein said at least one attachment element attaches said frame at said at least one window side to said apparatus housing.

10. An acquisition window as claimed in claim 9 wherein said attachment element is mechanically integrated into said frame.

11. An acquisition window as claimed in claim 1 wherein said at least one attachment element is formed as a strip.

12. An acquisition window as claimed in claim 1 wherein said at least one attachment element is formed as a ring.

13. An acquisition window as claimed in claim 1 comprising at least two attachment elements respectively disposed at least two opposite window sides, and wherein said x-ray permeable material is a foil that is tensioned between said at least two attachment elements.

14. A medical apparatus comprising:
an x-ray source situated in an apparatus housing, said x-ray source emitting an x-ray beam; and
an acquisition window comprising a window element comprised of an x-ray-permeable material disposed in a path of said x-ray beam, said window element comprising a plurality of sides, and at least one attachment element that releasably attaches at least one window side of said window element to said apparatus housing.

15. A medical apparatus as claimed in claim 14 comprising a plurality of apparatus components that, in combination with said x-ray source, are configured to acquire computed tomography data from a subject situated in said path of said x-ray beam.
