METHOD OF PRODUCING AND DISPLAYING AN IMAGE OF A 3 DIMENSIONAL VOLUME

摘要

An image of a multi-dimensional volume from a multi-dimensional object data set is displayed on a monitor, a target point (31) and a surface are identified, a target centric projection is then created by projecting information (33) from the target point onto the identified surface (32). Critical volumes (42, 43) are identified within the multi-dimensional volume and information from these is projected onto the identified surface. Points are selected on the surface and a rectilinear pathway (74) calculated between the selected points and the target point. Distance information between the target point and the identified surface is calculated for selected points. Distance information is projected onto the identified surface (1104). An embodiment is provided in which the critical volumes are enlarged (105) prior to projection (106). The projection may be produced around a selected point on the surface and displayed together with the multi-dimensional volume (1204).
