Embodiment Construction

[0096] figure 1 A system 1 for visualizing three-dimensional objects according to an embodiment is shown in . System 1 has a computing unit 20 , an interface 30 , a detection device 40 , a reproduction device 50 and a storage unit 60 . The calculation unit 20 is basically designed to calculate a visualization image VB of the three-dimensional object on the basis of the volume data VD describing the three-dimensional object. The volume data VD can be provided by the storage unit 60 to the computing unit 20 via the interface 30 .

[0097] The storage unit 60 can be designed as a central or decentralized database. The storage unit 60 can especially be part of a server system. The storage unit 60 can in particular be part of a so-called picture archiving and communication system (PACS). Volume data VD can be generated by medical imaging methods. For example, volume data VD may be generated by fluoroscopy, computed tomography (CT), magnetic resonance tomography (MR), ultrasoun...

Abstract

A computer-implemented method is for visualization of a three-dimensional object represented by volume data (VD) for a user in the form of a two-dimensional visualization image (VB) including a plurality of visualization pixels (VP). The method includes: providing an image synthesis algorithm designed for visualization of the three-dimensional object by mapping the volume data onto the visualization pixels; detecting an instantaneous viewing direction of the user; determining a focus area (FB) defined as a region of the visualization image, upon which the user focuses based upon the instantaneous viewing direction; adjusting the image synthesis algorithm such that the computing effort required for the mapping for visualization pixels outside of the focus area is lower than for visualization pixels inside of the focus area; and mapping volume data onto the visualization pixels with the adjusted image synthesis algorithm.

Description

technical field [0001] The invention is in the field of volume rendering, ie the display or visualization of three-dimensional volumes or three-dimensional objects. Background technique [0002] Modeling, reconstruction or visualization of three-dimensional objects has a wide range of applications in the fields of medicine (eg CT, PET), physics (eg electronic structure of macromolecules) or geophysics (property and location of formations). Usually, the object to be examined is irradiated (for example by means of electromagnetic or sound waves) in order to examine the properties of said object. Scattered radiation is detected and properties of the body are determined from the detected values. The results are typically produced in physical variables (eg density, tissue type, elasticity, speed) whose values ​​are determined for the body. Usually a virtual grid is used here, the values ​​of the variables are determined at the grid points of the virtual grid. The grid points a...
