Area of Science:

  • Cardiology
  • Medical Imaging
  • Ultrasound Technology

Background:

  • Detecting left ventricular wall motion abnormalities from stress-induced myocardial ischemia is challenging with traditional echocardiography.
  • Sequential videotape review of echocardiographic images hinders accurate comparison.

Purpose of the Study:

  • To develop an accessible and cost-effective digital stress-echocardiography system.
  • To improve the diagnostic capabilities of ultrasound for evaluating coronary artery disease.

Main Methods:

  • Utilized a Macintosh II personal computer with an 8-bit graphics card for offline digitization of 2-D echocardiographic images from videotape.
  • Employed public domain NIH Image software for image display and analysis, preserving image quality.
  • Developed a macro procedure for synchronized quad-screen display of cardiac cycles for side-by-side comparison.

Main Results:

  • The developed system allows for simultaneous-like review of rest and post-stress echocardiographic images.
  • Image quality and resolution were maintained, especially when using Super-VHS videotapes.
  • The macro procedure for image montage is efficient, comparable to commercial systems.

Conclusions:

  • A personal computer-based, low-cost digital stress-echo system can make this technique more clinically feasible.
  • This approach enhances the diagnostic power of ultrasound in assessing patients with known or suspected coronary artery disease.
