Blood flow and Oxygen saturation changes according to pressure effect in NIR breast cancer imaging study

摘要

NIR handheld LED breast cancer imaging is a novel design that we are using widely in clinical study. During the test, we found the pressure change may affect the signal from the breast, especially to the blood flow inside of tissue. In this paper, we will show a new design of the probe combined with pressure sensors. And, we also did 15 cases of normal person's breast test by using this design. We try to dig out how the pressure works and the relationships between the pressure effect to blood flow, also oxygen saturation in vivo. Some patients' data may be presented here too.
