Embodiment Construction

[0030] figure 1 A schematic representation of a medical imaging device 100 is shown. When performing an imaging exam of the patient 103 in the medical imaging apparatus 100, subtasks include positioning the patient 103 in an appropriate initial position for a topogram. The imaging device 100 is, for example, a computed tomography scanner (CT), a positron emission tomography scanner (PET-CT), a magnetic resonance tomography scanner (MRT) or a single photon emission computed tomography scanner and a computed tomography scanner. instrument (SPECT-CT).

[0031] To this end, the medical imaging apparatus 100 comprises a positionable table 101 for positioning a patient 103 to be subjected to a medical imaging examination, the positionable table 101 bringing the patient 103 into an isocenter for the examination. Positioning is possible in the vertical direction by changing the table height, and in the horizontal direction by changing the longitudinal table position. To this end, t...

Abstract

The present invention relates to a method for positioning a positionable table for a patient within a medical imaging device, having the steps of: determining (S101) a predetermined table position according to the organ or body part of the patient to be examined; Correcting correction data for the predetermined stage position; correcting (S103) the predetermined stage position based on the ascertained correction data; and positioning (S104) the stage at the corrected stage position.

Description

technical field [0001] The invention relates to a method for positioning a patient with a positionable table in a medical imaging device, and a medical imaging device with a positionable table for positioning a patient. Background technique [0002] Today, the positioning of a patient in a medical imaging device will be performed in two sub-steps, namely: firstly, a roughly preliminary positioning of the patient, where the table is driven into the annular channel (gantry) of the imaging device; secondly, a final, more precise Positioning, where height and longitudinal stage positions are again precisely compared manually using a laser cross. [0003] The approximate initial positioning is performed by a foot switch which is actuated to raise the patient to a fixed height and then moves the table into the annular channel until the foot switch is released. This approximate preliminary position is called "patient load". When this operation is performed by the foot switch, rou...
