Abstract

BACKGROUND Fluoroscopy is range ambiguous--the relative positions in three-dimensional space of two structures with superimposed silhouettes cannot be ascertained. The parallax effect can be used to overcome this problem, and was used to develop a technique of axillary/subclavian vein puncture. METHOD Patients requiring axillary/subclavian vein puncture… (More)
