Abstract

A method and an apparatus are provided for conveniently, quickly and intuitively adjusting a scanning region of a tomography device (1). At least one edge point (R1, R2) of a set-point scanning region (S') on a patient examination table (6) associated with the tomography device (1) is indicated by hand signals of a user. Via a distance sensor (11), mounted at a reference point (13) of the patient examination table (6), a distance from the edge point to the reference point is measured. From the measured distance, the position of the edge point (R1, R2) relative to the patient examination table (6) is determined, and a corresponding edge of a actual scanning region (S'') of the tomography device (1) is conformed to the derived position.

Description

technical field

[0001] The invention relates to a method for adjusting a scan field in a tomography system. The invention also relates to a device for carrying out the method. In this context, the term tomography device generally refers to a medical technology device, in particular a computed tomography device or a magnetic resonance tomography device, which operates according to the layered imaging method. Background technique

[0002] In particular, the so-called scan field must first be determined before the computerized tomography is performed on the patient. The scanning area refers to the body area of ​​the patient to be examined that is scanned during the examination of successive recordings of adjacent body layers and the area of ​​the patient's couch that corresponds to this body area.

[0003] Up to now, this scanning area has usually been determined by means of a topogrammbild with internally stored information taken in the preparatory phase of the actual examin...
