Problems solved by technology

[0003] It is therefore generally known that cardiac motion during tomographic acquisition can cause inconsistencies and impair image data through motion artifacts
This severely limits the clinical usability of the image data

Embodiment Construction

[0027] figure 1 with figure 2 A computed tomography system 1 according to the invention is shown in each case. In the example shown here, the patient P is lying on the patient couch 8 during the recording of the measurement data MEAS. The patient table 8 is designed to move the patient P along the system axis 9 during the tomographic recording. The radiation source 2 and the radiation detector 5 cooperating with the radiation source 2 rotate about the system axis 9 during the acquisition of the measurement data MEAS. The radiation source 9 emits radiation in such a way that it is substantially detectable by the radiation detector 5 . The radiation is attenuated by the respective examination object, in particular by absorption and reflection of the radiation. In the example shown here, the measurement data MEAS are a plurality of projections of the body part of the patient P, wherein the projections each describe the attenuation of radiation by the body part of the patient...

Abstract

A method, a computer program, a computer program product and a computed tomography system are disclosed. The image data is a spatially three-dimensional reconstruction. At least one value for an image metric of the image data is determined. A motion field for motion compensation of the image data is then determined on the basis of image data as a function of the image metric. Essentially, partial image data is determined, wherein the partial image data corresponds in each case to the spatially three-dimensional reconstruction from scan data of an angular sub-range. The motion field of the image data is determined at the control points via an optimization method as a function of the image metric, so that, thereafter, the partial image data is transformed in accordance with the motion of the motion field. New image data is then produced by merging the partial image data.

Description

technical field [0001] The invention relates to a method for motion compensation of image data as well as a computer program, a computer program product and a computed tomography system. Background technique [0002] Computed tomography is an imaging method mainly used in medical diagnosis as well as in the inspection of materials. In computed tomography, to record spatially three-dimensional image data, a radiation source and a radiation detector cooperating with the radiation source are rotated around the object under examination. Measurement data are recorded over an angular range during the swivel movement. The measurement data are projections which contain information about the attenuation of radiation by the examination object. Measurement data is also called raw data. Image data can then be reconstructed from these measurement data, for example by means of so-called filtered back-projection or by means of iterative reconstruction methods. If the examination object...
