This study introduces a novel data compression scheme for arterial pulse waveforms, crucial in traditional Chinese medicine and telemedicine. The pattern-matching method achieves high compression ratios with minimal distortion, improving data management for long-term monitoring.

Area of Science:

  • Biomedical Engineering
  • Medical Informatics
  • Traditional Chinese Medicine

Background:

  • Arterial pulse waveforms contain vital clinical information in Traditional Chinese Medicine.
  • Long-term recording of arterial pulse data is common in telemedicine and Picture Archiving and Communication Systems (PACS).
  • The large volume of arterial pulse data presents storage and transmission challenges.

Purpose of the Study:

  • To develop an efficient data compression scheme for arterial pulse waveform sequences.
  • To leverage the inherent correlations between successive arterial pulse beats for data reduction.
  • To minimize data distortion while maximizing compression ratios.

Main Methods:

  • A novel data compression scheme based on pattern matching was developed.
