Filed:

Sep 24, 1999

Appl. No.:

09/404772

Inventors:

Randall A. Havner - Atlanta GA, US
Stephen D. Ryan - Vernon WI, US
James F. Toman - Temecula CA, US

Assignee:

Rockwell Software Inc. - Milwaukee WI

International Classification:

G06F009/44
G05B011/01
G05B019/42

US Classification:

717163, 717162, 717164, 700 17, 700 86

Abstract:

A library manager holds related program fragments, for example, control logic fragments and visualization program fragments sharing the same control variables, in library files. Multiple copies of control logic program fragments are instantiated to develop a control program and of the control variable tags for each copy of the control logic program fragments are renamed to prevent conflicts. At a later time, visualization program fragments related to the control logic program fragments are identified by their common origin in the library manger. The control variables of these visual program fragments may then be automatically renamed by using their library files as a guide. The library files may also hold related non-program information.

International Classification:

A61B 8/08
A61B 8/12
A61B 8/00

Abstract:

The invention describes a novel implementation of ultrasound or OCT technology to approximate the dimensions of fluid-filled structures (when using ultrasound technology) or other structures (when using OCT technology). The invention in a preferred embodiment is an elongated member such as a catheter that uses ultrasound or OCT technology to approximate the dimensions of a structure into which the catheter has been placed. In a preferred embodiment, the catheter includes multiple ultrasound transducers arranged in an annular or circumferential configuration on, embedded into or within the body of the elongated member so that distance measurements can be obtained between the elongated member and the wall of the immediately facing structure (e.g., a fluid-filled lumen). Utilizing these measurements, the present invention approximates for the physician the shape and size of the structure into which the elongated member is placed. The invention also includes a method for producing three-dimensional images from two-dimensional images.
