METHOD AND POSITION DETERMINATION SYSTEM FOR DETERMINING A POSITION OF A TARGET REGION OF A PATIENT TO BE IRRADIATED IN AN IRRADIATION DEVICE

摘要

In a method for determining a position of a target region of a patient to be irradiated in an irradiation device, a patient is positioned on a patient positioning device having markers that are visible in magnetic resonance images. A magnetic resonance image data record is acquired showing a target area of the patient containing the target region, together with the markers. The magnetic resonance image data record is evaluated to determine location information describing the three-dimensional position of the target region relative to the markers. The patient positioning device with the unmoved patient is transported to the irradiation device. Target information describing the position of the target region in the irradiation device is determined from marker information indicating the position of the markers in the irradiation device, and the location information.

1. A method for determining a position of a target region of a patient to be irradiated in an irradiation apparatus, said method comprising:
positioning a patient on a patient positioning device comprising markers that are visible at least in magnetic resonance images; operating a magnetic resonance scanner to acquire a magnetic resonance image data record from the patient, showing a target area of the patient that contains the target region, together with said markers; evaluating said magnetic resonance image data record to determine location information therefrom that describes a three-dimensional position of said target region relative to said markers; transporting the patient on the patient positioning device, with the patient being unmoved from said patient position on said patient positioning device, to said irradiation device; and determining target information describing the position of the target region in the irradiation device using information identifying a position of said markers in said irradiation device, and said location information.
