Background:

  • Electrical impedance imaging requires synchronization with cardiac activity for accurate heart and pulmonary perfusion visualization.
  • Low signal-to-noise ratio necessitates temporal averaging to enhance image quality in impedance imaging.
  • Current methods face challenges in achieving sufficient temporal resolution for dynamic cardiovascular imaging.

Purpose of the Study:

  • To investigate and compare different electrocardiogram (ECG) gating techniques for synchronizing applied potential tomography (APT) data acquisition with the cardiac cycle.
  • To evaluate the effectiveness of various ECG gating methods in improving image quality and enabling visualization of pulsatile blood flow.
  • To explore strategies for enhancing the speed of image data acquisition and processing for dynamic cardiovascular imaging.
