CONTACT-FREE PHYSIOLOGICAL MONITORING DURING SIMULTANEOUS MAGNETIC RESONANCE IMAGING |
摘要 |
Devices and methods to measure and visualize the cardiac and respiratory signal of a human or animal subject during a magnetic resonance imaging (MRI) exam are described. This includes a video camera compatible with the MRI scanner, a means of transferring the video data away from the MRI scanner, a light source that illuminates the subject, and an algorithm that analyses the video stream and uses small image intensity changes and motion information to extract cardiac signal and respiratory signals of the subject. These methods make it practical to use optical tracking to monitor and correct for cardiac and respiratory motion during MRI, as well as provide basic patient monitoring with no physical contact to the subject. |
