Abstract
In a presentation device for the two-dimensional presentation of the volume data elements of a volume dataset, parts of the volume dataset can be selected by prescribing boundary surfaces. The boundary surfaces are displaceable. The selected volume can be presented as a perspective image rotating around a basic rotational axis. The rotational axis is selectable dependent on the positions of the volume data elements of the selection dataset. The rotational axis can be automatically determined by a computer unit.
Claims14
A presentation device comprising:
- a data memory for storing a volume dataset, representing a volume, comprising a plurality of volume data elements, each of said volume data elements having a volume position and a data value allocated thereto, said volume position designating a position in said volume of that volume data element;
- a computer connected to said data memory for generating a two-dimensional image of said volume, that is rotatable around a basic rotational axis, from said volume dataset, with said data elements having respective positions in said image determined by said volume position;
- a display connected to said computer for displaying said image;
- an input unit connected to said computer for prescribing at least one boundary surface to said computer which is used by said computer to divide said volume dataset into a selection dataset and a remaining dataset;
- and
- said computer using only volume data elements that are contained in said selection dataset for generating said two-dimensional image, and automatically determining said basic rotational axis dependent on the volume positions of the volume data elements in the selection dataset.
A presentation device as claimed in claim I wherein said boundary surface is interactively displaceable via said input unit.
