Method and apparatus for eliminating motion artifacts of bio signal using personalized bio signal pattern
First Claim
Patent Images
1. A method of eliminating motion artifacts in a bio signal, the method comprising:
- acquiring a bio signal from a patient;
generating a reconstruction signal of the acquired bio signal by successively connecting bio signal patterns of the patient with each other so that locations of peaks in the bio signal patterns of the patient correspond to locations of peaks in the acquired bio signal; and
eliminating motion artifacts in the acquired bio signal based on a difference between the reconstruction signal and the acquired bio signal.

Abstract
An apparatus for eliminating motion artifacts in a bio signal includes a bio signal acquisition unit configured to acquire a bio signal from a patient; a reconstruction signal generator configured to generate a reconstruction signal of the acquired bio signal based on a result of comparing the acquired bio signal with a bio signal pattern of the patient generated using a bio signal measured from the patient before acquiring the bio signal from the patient; and a motion artifact elimination unit configured to eliminate motion artifacts in the acquired bio signal based on a difference between the reconstruction signal and the acquired bio signal.
