REGISTRATION OF MEDICAL IMAGES Russian patent published in 2019 - IPC G06T7/00 A61B5/55 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical technology, namely to image processing means for registration purposes. In the method, an image processing device that can perform registration of at least two images (I₁, I₂) of object (P) contains a “global registration module” to perform global registration (GR) of images (I₁, I₂) using the specified registration algorithm and the first parameter vector (p₀), a “selection module” for selecting a region of interest, called ROI, in images, a “local registration module” for implementing at least one local registration (LR1, ..., LRs, ..., LRn) of images within the selected ROI using a given registration algorithm and a different parameter vector (p₁, p₂, ..., p_n), moreover, the parameter vector is defined for at least one local coordinate reference based on an automatic ROI analysis, which contains an estimate of the intensity ranges, intensity histograms, image contours, contour histograms, entropy measurements, residual image intensity range, and/or anatomical position. Further, the method for registration is carried out by means of an image processing device. And the medical imaging apparatus comprises at least one imaging device, a device for processing images coming from the imaging device.

EFFECT: use of inventions allows to improve the coordinate reference of images.
