Patent ID: 7636484

Claim:
A method for the formation of a selective rendering of body structures of an object to be examined from a primary image data set that is executed on a computer, the computer including computer memory that stores instructions that when executed on the computer, cause the computer to perform the steps of: forming at least one pixel group (BG 1 -BG 16 ) which comprises pixels from the primary image data set which are in conformity with predetermined filter criteria; forming at least one pixel list by selection and/or deselection of at least one pixel group in conformity with predetermined criteria; marking the pixels of the pixels groups of the at least one pixel list; forming a filtered secondary image data set which includes the marked pixels; and forming the rendering from the secondary image data set, the marked pixels being rendered separately in highlighted or suppressed form; wherein a plurality of pixel groups is defined, wherein a combination data tree is formed by assigning each pixel group (BG 1 -BG 16 ) to a node (D 1 -D 10 , C 1 -C 11 , B 1 , B 2 , A 1 ), and that the nodes are logically assigned to one another in conformity with a predetermined combination criterion and the selection and deselection are performed by selection and/or deselection of the nodes.
