Estimating the term…
A method for measuring vibration transmittance of a sternum noninvasively includes producing vibration, transmitting the vibration to a first side the sternum through skin and soft tissues, obtaining response data of the sternum from a second side of the sternum through skin and soft tissues, which first and second sides of the sternum are on different sides of the midline of the sternum, and processing said response data for determining transmittance of vibration of the sternum. The response data may be used for defining state of a patient such as sternal instability of the breastbone or abnormal healing in the sternum after open chest surgery by surgeons.
A method for measuring vibration transmittance of a sternum noninvasively with an apparatus, comprising:
A system for measuring vibration transmittance of a sternum noninvasively, wherein the system comprises a device comprising a processor and a memory including computer program code for producing vibration, a transmitter for transmitting the vibration with spectral content with varying frequency to a first side of the sternum through skin and soft tissues, by an accelerometer for obtaining response data of the sternum from a second side of the sternum through skin and soft tissues, which first and second sides of the sternum are on different sides of the midline of the sternum, and wherein there is a handle between the transmitter and the accelerometer, so that the distance of the transmitter and the accelerometer remains at a constant distance within 2 to 5 centimeters from the midline of the sternum during measuring, and wherein the device is further arranged to process said response data for determining integrated transmittance of vibration of the sternum.
A device for measuring sternal vibration transmittance of a sternum noninvasively, wherein the device comprises:
