移植可能および挿入可能な受動型タグ
Document Type and Number:
Japanese Patent JP4540929
Kind Code:
B2
Abstract:
Apparatus for determining the position of an object within a body of a subject includes at least one acoustic wave generator, adapted to direct a first acoustic wave toward the body. An acoustic tag (60) is adapted to be fixed to the object, the tag being constructed so as to reflect acoustic waves at first and second frequencies with first and second spatial patterns, respectively. One or more detectors are adapted to detect the reflected acoustic waves and to generate signals responsive thereto. A signal processor is coupled to process the signals so as to determine an angular orientation coordinate of the object in the body.
