Cavity Determination Apparatus

摘要

The invention relates to a cavity determination apparatus for determining a cavity (3) within an object (2), in particular for determining the location and dimensions of a heart chamber within a person. A bendable segment of an introduction element (5) is arranged within the cavity in different arrangements, wherein curves defined by the bendable segment in the different arrangements are determined by a curve determination unit (7). A cavity reconstruction unit (8) reconstructs the cavity based on the determined curves. Thus, not only single locations within the cavity are acquired and used for reconstructing the cavity, but larger curves. A lot of spatial information can therefore be acquired and used very fast. This allows reconstructing the cavity with improved quality in a relatively short time.
