Method and arrangement for controlling an X-ray beam
First Claim
1. A method for controlling an X-ray device having at least one X-ray tube and at least one X-ray detector that is movable relative to said at least one X-ray tube, said method comprising the steps of:
- before activating an X-ray tube, designated for an examination, to emit X-rays, automatically electronically checking whether an X-ray detector, also designated for said examination, said been activated;
automatically electronically obtaining position data identifying a position of at least one of said designated X-ray tube and said designated X-ray detector;
using said position data, automatically electronically determining respective positions of said designated X-ray tube and said designated X-ray detector relative to each other, and comparing said relative positions to correct relative positions for said examination; and
allowing activation of said designated X-ray tube to emit X-rays in said examination only if said designated X-ray detector is activated and said designated X-ray tube and said designated X-ray detector are in said correct relative positions.

Abstract
In a method and apparatus for controlling an X-ray device having at least one X-ray tube and at least one X-ray detector, wherein the X-ray tube and/or the X-ray detector are movably arranged, before an activation of an X-ray tube indicated for a desired measurement, an automatic check is made out as to whether an X-ray detector indicated for the desired measurement is activated. Position data of the appertaining X-ray tube and/or appertaining X-ray detector are also automatically determined and using the identified position data, the relative positions of the appertaining X-ray tube and of the appertaining X-ray detector relative to one another are identified. The X-ray tube is enabled for activation, or is automatically activated, only when the X-ray detector is activated and the X-ray tube and the X-ray detector are suitably positioned relative to one another for the desired measurement.

11. An X-ray system comprising:
-
at least one X-ray tube;
at least one X-ray detector that is movable relative to said at least one X-ray tube;
a position determination system for automatically electronically obtaining position data identifying a position of at least one of an X-ray tube designated for an examination and an X-ray detector designated for said examination, before activating said designated X-ray tube to emit X-rays in said examination;
a position correlation unit for, using said position data, automatically electronically determining respective positions of said designated X-ray tube and said designated X-ray detector relative to each other, and for comparing said relative positions to correct relative positions for said examination; and
an activation unit which checks whether said designated X-ray detector is activated and which allows activation of said designated X-ray tube to emit X-rays in said examination only if said designated X-ray detector is activated and said designated X-ray tube and said designated X-ray detector are in said correct relative positions. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
