摘要： System and method for enabling intra-operative selection of an image registration transformation for use in displaying a first image dataset and a second image dataset in correspondence with one another. Image dataset acquisition devices (12, 14) obtain the first and second image datasets. A similarity function indicative of a likelihood that the first and second image datasets are in correspondence with one another is computed by a processor (16) and then a ranking of each of a plurality of local maxima of the similarity function is determined. Registration transformations derived from a plurality of the local maxima are displayed on a display (18), and using a user-interface (22), a physician can select each registration transformation to ascertain visually whether it is the clinically-optimal registration transformation for subsequent use.

摘要： An optical detection tool employs a surgical end-effector (30) and an optical fiber (20). In operation, the surgical end-effector (30) is navigated within an anatomical region relative to an object foreign to the anatomical region and the optical fiber (20) generates an encoded optical signal indicative of a strain measurement profile of the optical fiber (20) as the surgical end-effector (30) is navigated within the anatomical region. The optical fiber (20) has a detection segment in a defined spatial relationship with the surgical end-effector (30). The strain measurement profile represents a normal profile in the absence of any measurable contact of the foreign object with the detection segment of the optical fiber (20). Conversely, the strain measurement profile represents an abnormal profile in response to a measurable contact of the foreign object with the detection segment of the optical fiber (20).

摘要： A method, system and apparatus for manufacturing anatomically and functionally accurate soft tissue phantoms with multimodality characteristics for imaging studies is disclosed. The organ/tissue phantom is constructed by filling a container containing an organ having inner vasculature therein with a molten elastomeric material; inserting a plurality of rods with bumps thereupon through the container and the organ; allowing the molten elastomeric material to harden and cure; removing the organ; replacing the organ with a plurality of elastomeric segments; and removing an elastomeric segment and replacing the void created thereupon with molten PVA to create a PVA segment; allowing the molten PVA segment to harden and cure; and repeating the creation of PVA segments until all the elastomeric segments have been removed, such that each successive molten PVA segment adheres to and fuses with the previous hardened PVA segment so as to form an approximately complete organ phantom cast. The organ/tissue phantom is completed by inserting the approximately complete organ phantom cast inserting upside-down into a fixture made from the bottom-most elastomeric segment, which contains molten PVA; and allowing the molten PVA to harden and cure.
