摘要: An invasive medical probe includes an insertion tube, having a distal end for insertion in a body cavity of a patient. A metallic material is disposed over the distal tip of the insertion tube and extends from the tip so as to cover a portion of the distal end. An acoustic sensor is contained entirely within the portion of the distal end of the insertion tube that is covered by the metallic material.

摘要: Visualization of a probe when impedance-based measurement technology is being used is improved by stabilizing a displayed image of the probe or catheter. Using a model of reasonable probe shapes and a matching algorithm, an erroneous probe image is adjusted so that it assumes a realistic shape on a display. A range of positional variations is also incorporated in the model. When an apparent probe position exceeds a permissible range of motion, the probe image is constrained to a realistic position.
