Method for digital image processing of medical images recorded with a medical imaging device and complete medical system

A complete medical system for digital image processing of medical images of an examination object recorded by an imaging device, the complete medical system comprising:

• a provisioning unit configured to provide at least one medical image;
• an image processing unit configured for processing and frequency decomposition of medical images;
• a control unit configured to actuate the complete medical system;
• and
• an output unit configured to output the processed medical image,
• wherein the complete medical system is configured for digital image processing of medical images of an examination object recorded with a medical imaging device, wherein a recorded medical image is decomposed into a plurality of levels using frequency decomposition according to Gaussian-Laplacian decomposition, the complete medical system being configured for digital image processing of medical images comprising the complete medical system being configured to:
• provide a respective band-pass or low-pass image for calculating an associated gradient field for at least a first level and for a further level of frequency decomposition of the recorded medical image;
• determine a dot product from the gradient field of the band-pass or low-pass image of the first level and the gradient field of the band-pass or low-pass image of the further level, which is adapted with respect to an image resolution of the band-pass or low-pass image;
• ascertain a mask image for the first level, the ascertainment of the mask image comprising normalization of the dot product;
• integrate the ascertained mask image for the first level into a parameterization for processing the band-pass or low-pass image of the first level;
• and
• perform an image processing operation with the mask image integrated into the parameterization.

In a non-transitory computer-readable storage medium that stores instructions executable by one or more processors for digital image processing of medical images of an examination object recorded with a medical imaging device, wherein a recorded medical image is decomposed into a plurality of levels using frequency decomposition according to Gaussian-Laplacian decomposition, the instructions comprising:

• providing a respective band-pass or low-pass image for calculating an associated gradient field for at least a first level and for a further level of frequency decomposition of the recorded medical image;
• determining a dot product from the gradient field of the band-pass or low-pass image of the first level and the gradient field of the band-pass or low-pass image of the further level, which is adapted with respect to an image resolution of the band-pass or low-pass image;
• ascertaining a mask image for the first level, the ascertaining of the mask image comprising normalizing the dot product;
• integrating the ascertained mask image for the first level into a parameterization for processing the band-pass or low-pass image of the first level;
• and
• performing an image processing operation with the mask image integrated into the parameterization.
