NON-LINEAR ECHOGENIC MARKERS

摘要

Medical devices include echogenic subregions and echolucent subregions arranged in an alternating pattern and having exogenous features. Examples include metal printing and cast metal being applied to a plastic structure. Other examples include a fluid contrast agent including microbubbles housed in compartments within a structure. Additional examples include small resonators built into a structure for resonating at a specific frequency and imageable with a harmonic imaging mode of an ultrasound imaging system.

主权项

1. A medical device detectable with ultrasound imaging equipment comprising:
an echogenic region, wherein the echogenic region includes a plurality of first subregions being defined by borderlines and a plurality of second subregions, wherein the first subregions include an echogenic enhancement, and wherein the first subregions and second subregions are arranged in an alternating pattern wherein at least one second subregion lies between each pair of first subregions with no borderlines shared between any pair of the first subregions.
