VISUALISATION OF RECONSTRUCTED IMAGE DATA Russian patent published in 2018 - IPC A61B5/00 G16H30/00 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical equipment, specifically to means of visualisation of reconstructed image data with reference to computed tomography. Method comprises steps of processing projection data with a first reconstruction algorithm and reconstructing first reconstructed volumetric image data, wherein the first reconstructed volumetric image data has a first 3D noise function, processing the same projection data with a second different reconstruction algorithm and reconstructing second reconstructed volumetric image data, wherein the second reconstructed volumetric image data has a second 3D noise function, which is different from the first 3D noise function, visually presenting the first or the second reconstructed volumetric image data in a main viewport and visually presenting a sub-portion the other of the first or the second reconstructed volumetric image data in a region of interest overlaid over a sub-portion of the main viewport. System for visualising reconstructed image data comprises a reconstruction apparatus that reconstructs the same set of projection data with different reconstruction algorithms and visually displays the first or second reconstructed image data with an overlay including a sub-portion of the de-noised reconstructed image data and superimposed over a sub-portion of the visually displayed image data.

EFFECT: use of inventions increases the sensitivity of diagnosis.
