Claim 15:
16. A medical system, comprising:
at least one processor of a computer, causing the computer to perform a method having steps comprising:
acquiring image position data describing a spatial transformation between a spatial position ultrasound images acquired by an ultrasound probe and at least one of: a tracked spatial position of the ultrasound probe as determined via a medical tracking system and a spatial position of a housing of an ultrasound probe;
acquiring first image data describing a first two-dimensional ultrasound image received from the ultrasound probe and displaying a structure in a first image plane;
acquiring second image data describing a second two-dimensional ultrasound image received from the ultrasound probe and displaying the structure in a second image plane intersecting with the first image plane along an intersection line;
determining first intersection data based on the first image data and based on the spatial transformation described by the image position data, wherein the first intersection data describes image content of the first two-dimensional ultrasound image within a first linear intersection set of pixels along the intersection line that is defined by the intersecting first and second image planes;
determining second intersection data based on the second image data and based on the spatial transformation described by the image position data, wherein the second intersection data describes image content of the second two-dimensional ultrasound image within a second linear intersection set of pixels along the intersection line;
determining similarity data based on the first intersection data and the second intersection data, wherein the similarity data describes a grade of similarity between the image content of the first two-dimensional ultrasound image within the first linear intersection set of pixels and the image content of the second two-dimensional ultrasound image within the second linear intersection set of pixels;

at least one electronic data storage device storing at least the image position data; and
a medical device for carrying out a medical procedure on a patient,
wherein the at least one processor of the computer is operably coupled to the at least one electronic data storage device for acquiring, from the at least one electronic data storage device, at least the image position data, and
wherein the at least one processor of the computer is operably coupled to the medical device for issuing a control signal to the medical device for controlling the operation of the medical device on a basis of the similarity data.
