System and method for evaluating a state of health of a coronary artery

摘要

Method and apparatuses are described to evaluate a state of health of a coronary artery. Vibrational cardiac data from a transducer is received from a first location. The transducer measures vibration of a surface of a human's body non-invasively. The vibrational cardiac data is processed in a second location to create processed vibrational cardiac data. The processing includes separating an unwanted coronary event from the vibrational cardiac data. The processing further includes performing a time-to-frequency transformation on the vibrational cardiac data from a portion of a diastolic interval within a heart cycle to obtain a vibrational frequency power spectrum estimate. The processing includes evaluating a state of health of the coronary artery using the processed vibrational cardiac data.

1. A method to evaluate a state of health of a coronary artery, comprising:
receiving from a first location vibrational cardiac data from a transducer, the transducer measures vibration of a surface of a human's body non-invasively; and processing the vibrational cardiac data with a data processing system in a second location to create processed vibrational cardiac data, the processing further comprising:
separating an unwanted coronary event from the vibrational cardiac data;performing a time-to-frequency transformation on the vibrational cardiac data from a portion of a diastolic interval within a heart cycle to obtain a vibrational frequency power spectrum estimate; andevaluating non-invasively the state of health of the coronary artery using the processed vibrational cardiac data.
