1. A method of visualising a dynamic anatomical structure, the method comprising:
a) providing a sequence of three-dimensional medical images spanning a time period, each three-dimensional medical image of the sequence showing a dynamic anatomical structure at a point in time during the time period;
b) providing a dynamic model of at least a part of the dynamic anatomical structure, wherein the dynamic model has been derived from and is registered with the sequence of three-dimensional medical images;
c) determining a volume of interest containing an anatomical feature of interest within each of the three-dimensional medical images, wherein the volume of interest follows a position and/or a shape of the anatomical feature of interest across the time period, and wherein the volume of interest is smaller than a complete field of view of the three-dimensional medical images; and
d) providing a three-dimensional visualisation environment for displaying the dynamic anatomical structure across the time period, wherein a visualisation corresponding to a particular point in time within the time period comprises
(i) a volume rendering of the volume of interest of the three-dimensional medical image corresponding to the particular point in time; and
(ii) a visualisation of the dynamic model at the particular point in time and in the same coordinate system as the volume rendering of the volume of interest.
