METHOD OF OPTIMISING MAXIMUM INTENSITY PROJECTION TECHNIQUE FOR RENDERING SCALAR THREE-DIMENSIONAL DATA IN STATIC MODE, IN INTERACTIVE MODE AND IN REAL TIME Russian patent published in 2014 - IPC G06T15/08 G06T19/20 

FIELD: physics.

SUBSTANCE: method of optimising maximum intensity projection technique for rendering scalar three-dimensional data in static mode, in interactive mode and in real time. The method comprises fragmenting the entire volume of scalar three-dimensional data of a voxel array into a set of sub-volumes consisting of voxels; determining a subset of sub-volumes located along a viewing beam; determining pixel colour as a maximum intensity value from the subset of sub-volumes belonging to the viewing beam. The voxel array is reduced to a type where the length of the edge of the cube of a voxel is equal to the length of the side of the square of a pixel, from the set of which an image is then formed. The range of voxel intensity values of the voxel array is taken equal to the number of elements of colour sets used for the image of the pixel array. Boundaries of the voxel array are rendered in the form of edges of a rectangular parallelepiped.

EFFECT: high rate of computation by reducing the amount of random-access memory used when constructing an image.
