A computer implemented method is disclosed for identifying a pose of a probe by registering an ultrasound image with volumetric scan data. The volumetric scan data is processed () to determine simulated ultrasound images corresponding with a plurality of different poses of the probe. A feature vector is extracted () from each of the simulated ultrasound images and from the ultrasound image. The feature vector from the ultrasound image is compared () with each feature vector of the simulated ultrasound images to determine a distance or similarity for each simulated ultrasound image. At least one candidate image is selected (), the at least one candidate image comprising a subset of the simulated ultrasound images that best matches the ultrasound image, based on the distance or similarity. The pose of the probe is identified () from the at least one candidate image.
