Embodiment Construction

[0027] Medical navigation systems require a registration procedure to align the coordinate systems of the navigation system and the patient. The fiducial markers attached to the patient allow semi-automatic or fully automatic registration if a roadmap image including the fiducial markers can be obtained. However, in many cases the use of fiducial markers is not feasible and a potentially time-consuming and inaccurate manual registration procedure is necessary. The present principles provide a system and method for fast and accurate automatic or semi-automatic registration. In particularly useful embodiments, pre-procedural and post-procedural imaging are utilized to combine a prescribed set of image acquisitions in standard imaging planes.

[0028] These embodiments provide a system and method to automatically obtain an internal organ, such as the liver, from an ultrasound (US) image to a previous preoperative image volume (e.g., CT or CT) during an interventional or diagnost...

Abstract

A system and method for image registration includes tracking (508) a scanner probe in position along a skin surface of a patient. An image plane corresponding to the location is acquired (510). A three-dimensional volume of the region of interest is reconstructed (512) from the image plane. A search of an image volume is initialized (514) to determine a physical constraint for registering the image volume and the three-dimensional volume by employing pose information of the scanner probe during image plane acquisition and physical constraints of the scanner probe pose. candidate image. The image volume is registered with the three-dimensional volume (522).

[0001] Government Rights: [0002] This invention was made under a US Public Health Service Cooperative Research and Development Agreement (CRADA No. NCI-NIHCC-01864). The US Government has certain rights in this invention. [0003] Cross References to Related Applications [0004] This application claims priority to US Provisional Patent Application No. 61 / 448714, filed March 3, 2011, which is hereby incorporated by reference in its entirety. technical field [0005] The present disclosure relates to medical systems, and more particularly, to systems and methods for device navigation using coordinated registration between different imaging modalities. Background technique [0006] Surgery and minimally invasive treatments require reliable and precise navigation along predefined paths to predetermined target points. Multiple interventions are guided based on pre-procedural high-resolution three-dimensional (3D) images acquired from the region of interest. Typically, a co...
