Abstract:
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 for generating a perspective, two-dimensional image of said volume from said volume dataset, said image covering a spatial angle and having a point of vision on an optical axis; a display connected to said computer for displaying said image; an input unit connected to said computer for entering first interactive inputs to said computer to display said point of vision along said optical axis, and for entering second interactive inputs into said computer for rotating said point of vision, and therewith said spatial angle, around a basic rotational axis, said basic rotational axis intersecting said optical axis at a basic intersection angle in a pivot point; and said computer automatically selecting volume data elements within said spatial angle, as selected volume data elements, and determining said pivot point dependent on the respective data values of the selected volume data elements.
