David Lyons - Rye NY

International Classification:

3009

US Classification:

D30153

US Patent:

51615363, Nov 10, 1992

Filed:

Mar 22, 1991

Appl. No.:

7/673949

Inventors:

David Vilkomerson - Princeton NJ
David Lyons - Trenton NJ

Assignee:

Catheter Technology - North Brunswick NJ

International Classification:

A61B 800

US Classification:

12866007

Abstract:

An ultrasonic imaging system employs a processing circuit which enables the imaging system to accurately display the location of an element in a body by utilizing a transducer which provides an electric signal when an ultrasonic wave impinges thereon. The electric signal is processed to determine the maximum amplitude signals during an entire frame of the ultrasonic imaging system. The signals are characterized in terms of the line at which the signal appears or the ray at which the signal appears and the pixel or location along that line. This information regarding ray and pixel serves as X-Y coordinates enabling one to accurately locate the element and transducer on the displayed image by intensifying the display at that location or by adding color or by producing some other visual effect such as blinking, and so on. Thus the disclosed apparatus in its various forms provides ultrasonic position indication without adjustment whereby one shows the exact location of the localizing transducer.

Filed:

Jan 23, 1986

Appl. No.:

6/821850

Inventors:

David J. Lyons - Trenton NJ

Assignee:

Princeton Electronics Products, Inc. - North Brunswick NJ

International Classification:

H04N 701

US Classification:

358140

Abstract:

A method and apparatus for converting an input video signal having P input lines, P being an integer much greater than one, into an output video signal having Q output lines, Q being an integer much greater than one but different than P. The conversion is preferably carried out using a linear interpolation method wherein the video information in the input signal is evenly distributed throughout the video output signal. The input lines are stored in small groups of M input lines and the output signal is generated in groups of N output lines. Each group of output lines is generated shortly after the receipt of an associated group of input lines.
