Area of Science:

  • Biomedical Engineering
  • Surgical Technology
  • Medical Diagnostics

Background:

  • Remote surgery necessitates advanced automated sensors and communication systems.
  • The NASA Smart Probe Project specifically addresses the sensor component for enhanced surgical capabilities.

Purpose of the Study:

  • To develop and evaluate a real-time tissue identification system for remote surgery and medical diagnostics.
  • To assess the efficacy of the NASA Smart Probe in distinguishing between normal, benign, and malignant tissues.

Main Methods:

  • Utilized neural networks and multi-microsensor data for real-time tissue signature analysis.
  • Employed two probe configurations: an 8-microsensor probe for rodent studies and a 21-gauge needle probe for human breast cancer diagnosis.
  • Collected multisensor data at a rate of 100 updates per second using PCs.
