Embodiment Construction

[0020] The following description focuses first on reducing the degrees of freedom required for 3D manipulation to 2D mouse gestures, and secondly on providing automatic feedback to the user in accordance with an appropriate rendering scheme that covers the sphere of influence of shape manipulation.

[0021] A method is described that facilitates shape editing in the context of medical image segmentation using shape models and / or free-form deformation methods.

[0022] The following description focuses on various embodiments of the present invention that are applicable to image analysis systems, and in particular to medical image analysis systems capable of shape editing. However, it will be appreciated that the invention is not limited to this application, but may be used in many other applications where shape editing of images is desired.

[0023] According to one embodiment, a method is provided for intelligently adapting an object interaction, manipulation and presentation ...

Abstract

A method and an apparatus for interactively manipulating a shape of an object, comprises selecting an object to be manipulated and rendering the object in dependence of a manipulation type. The method provides a smart object adapted interaction, manipulation and visualization scheme in contrast to previous display driven schemes. The method allows efficient shape manipulation by restricting the degrees of freedom for the manipulation to the meaningful ones for a given object or object part, thus allowing to reduce e.g. a 3D interaction to a 2D interaction.

Description

technical field [0001] The present invention is generally in the field of image analysis. More specifically, the present invention relates to models for interactive shape editing and rendering of e.g. anatomical structures, and for measurement of geometrical shape properties of such structures from 2D, 3D and 4D patient data such as X X-ray, computed tomography CT, magnetic resonance imaging MRI and ultrasound US. Background technique [0002] Interactive devices for drawing and editing graphical shapes are encountered in almost all medical applications. These interactive means may be based on modifications to the outlines of graphical shapes. Outlines can be active or passive, open or closed, smooth, e.g. interpolated using Bezier curves, or they can consist of multiple line segments. For example, contours are used for modeling, segmentation, and measurement tasks. [0003] There are basically two ways to draw contours, point by point or freehand. In the case of freeha...
