US Patent:

50661485, Nov 19, 1991

Filed:

Jul 31, 1990

Appl. No.:

7/560702

Inventors:

Paul T. Bryant - Bowie MD
Joseph F. Weller - Fort Washington MD
Lew Goldberg - Fairfax VA

Assignee:

The United States of America as represented by the Secretary of the Navy - Washington DC

International Classification:

G02B 628

US Classification:

385 24

Abstract:

A bi-directional optical transmission system for radio frequency electrical nergy includes first and second transmitter/receiver stations which transmit and receive light signals along an optical path therebetween. Each station includes a laser transmitter for transmitting a carrier light beam which is intensity modulated by a synchronization of an input radio frequency electrical signal. A photodetector at each station detects the intensity variations of the carrier light beam from the other station and outputs a respective radio frequency electrical signal which is synchronized with the radio frequency electrical input signal of the other station. A beam splitter is provided between the optical path at both the laser transmitter and photodetector to split the light beams incident thereon into a pass portion and angularly reflected portion. An isolator device also is provided between the laser transmitter and beam splitter to isolate the laser transmitter from back reflections. Preferably, the isolator is a Faraday isolator, and additionally or alternatively the laser transmitters transmit at widely separate wavelengths.

Abstract:

Systems and methods for generating patient-specific surgical guides comprising: capturing a first and second images of an orthopedic element in different reference frames using a radiographic imaging technique, detecting spatial data defining anatomical landmarks on or in the orthopedic element using a neural network, applying a mask to the orthopedic element defined by an anatomical landmark, projecting the spatial data from the first image and the second image to define volume data, applying the neural network to the volume data to generate a reconstructed three-dimensional (“3D”) model of the orthopedic element; and calculating dimensions for a patient-specific surgical guide configured to abut the orthopedic element.
