BONE SUPPRESSION IN X-RAY IMAGING Russian patent published in 2018 - IPC A61B6/03 G06T7/40 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medicine, specifically to medical image viewing in relation with navigation in X-ray imaging. Medical image viewing device for navigation in X-ray imaging comprises an image data providing unit, a processing unit and a display unit. Image data providing unit is configured to provide an angiographic image of a region of interest of an object. Processing unit is configured to identify a suppression area for partial bone suppression within the angiographic image and to identify and locally suppress predetermined bone structures in the angiographic image in the suppression area, to generate a partly-bone-suppressed image. Display unit is configured to display the partly-bone-suppressed image. Medical imaging system (20) comprises an X-ray image acquisition device and a medical image viewing device. X-ray image acquisition device comprises an X-ray source and an X-ray detector and is configured to provide X-ray images of an object. Method for providing improved X-ray image navigation information comprises steps a) providing an angiographic image of a region of interest of an object; b) identifying a suppression area for partial bone suppression within the angiographic image; c) identifying and locally suppressing predetermined bone structures in the angiographic image in the suppression area, wherein a partly-bone-suppressed image is generated; d) displaying the partly-bone-suppressed image. Computer-readable medium on which the computer program element for controlling the device is stored, which, when executed by the processing unit, is configured to perform the method steps.

EFFECT: group of inventions provides easier perception while at the same time providing visibility of more detail.
