1. A medical imaging method, comprising:
inserting an ultrasound probe into an organ of a body, the ultrasound probe comprising:
a two-dimensional (2D) ultrasound transducer array; and
a sensor configured to output signals indicative of a position and orientation of the 2D ultrasound transducer array inside the organ;
using the signals output by the sensor, determining, by a processor, voxel locations in each three-dimensional (3D) image acquired by the 2D ultrasound transducer array;
using the determined voxel locations in each 3D image, compensating, by the processor, for probe movement by averaging the voxel locations of the 3D images;
using the averaged 3D images, forming, by the processor, a voxel-location-compensated rendering of at least a portion of the organ; and
presenting, by the processor, the compensated rendering to a user without using a correlation function.
