1. A computer-implemented method of processing medical image data, the method comprising:
receiving a first set of data representing a first three-dimensional medical image produced by a medical imaging instrument;
receiving a second set of data representing a second three-dimensional medical image produced by the medical imaging instrument;
generating a first two-dimensional medical image by projecting the first set of data onto a first plane;
generating a second two-dimensional medical image by projecting the second set of data onto the first plane;
calculating a first spatial registration that exists between the first two-dimensional medical image and the second two-dimensional medical image in the first plane;
generating a first correction vector based on the spatial registration;
modifying the second set of data by applying the correction vector to one or more of the datum in the second set of data; and
generating a first combined set of data representing a processed three-dimensional medical image by combining the first set of data and the modified second set of data;
receiving a third set of data representing a third three-dimensional medical image produced by the medical imaging instrument;
generating a third two-dimensional medical image by projecting the third set of data onto the first plane;
generating a fourth two-dimensional medical image by projecting the first combined set of data onto the first plane;
calculating a second spatial registration that exists between the third two-dimensional medical image and the fourth two-dimensional medical image in the first plane;
generating a second correction vector based on the second spatial registration;
modifying the combined set of data by applying the second correction vector to one or more of the datum in the combined set of data; and
generating a second combined set of data representing a second processed three-dimensional medical image by combining the third set of data and the modified combined set of data.
