Abstract: A stent alignment system includes an implantable stent and catheter that allows the ability to precisely control translational and rotational position in a vessel of the implantable stent and catheter.

Abstract: In an interventional breast procedure, a magnetic resonance tracking sequence (80) is executed to determine (i) tracked positions of a plurality of active probe tracking coils (50) disposed with a probe (42) of an interventional instrument (40) and (ii) tracked positions of one or more active assembly tracking coils (52) disposed with a breast coil assembly (20). A probe tip position and angulation respective to the breast coil assembly is determined (84) based on the tracked positions. Conformance with a probe trajectory (88) of the determined probe tip position and angulation respective to the breast coil is verified (92).

Abstract: In a breast imaging method, magnetic resonance data are acquired of one or both breasts of a subject (16) using a breast coil (20, 20?) coupled with said one or both breasts. The acquiring employs at least four independent channels (41, 42, 43, 44, 45, 46; 61, 62, 63, 64, 65, 66) per breast. The acquired magnetic resonance data are processed to generate at least one of (i) an image, (ii) a spectrum, and (iii) elasticity data. The at least four independent channels per breast are suitably embodied as a dual breast coil (20) including left breast conductors (31, 32, 33, 34, 35, 36) defining at least four independent left breast acquisition channels (41, 42, 43, 44, 45, 46) and right breast conductors (51, 52, 53, 54, 55, 56) defining at least four independent right breast acquisition channels (61, 62, 63, 64, 65, 66).

Abstract: An expansion joint and flexible seal for refractory lined flues includes a flexible insulating body having a pair of end faces, a pair of lateral faces and a longitudinal dimension. The flexible seal further includes a filter element positioned adjacent to one of the end faces and extending in the longitudinal dimension. The filter element is attached to the insulating body and the assembly may be placed with other seal assemblies in endwise fashion around the periphery of a pair of opposing flue members. A further external pressure seal is provided, mounted to each end of the flue elements.
