EKV

EKV: Maximum Frame Rate Imaging for Maximum Resolution

EKV, or ECG-gated Kilohertz Visualization, allows for increased temporal and spatial resolution imaging. By averaging multiple cardiac cycles, typical B-mode frame rates are increased from ~300 frames/sec to up to 10,000 frames/sec! This simple and quick acquisition mode generates presentation quality videos that accurately resolve small animal cardiac motion, with heart rates commonly between 300 and 600 bpm.

EKV helps with measuring a variety of normal and disease states including:

  • Myocardial wall motion
  • Abdominal aortic aneurysm models
  • Pulsed wave velocity measurements in atherosclerosis
  • Valvular dynamics
