Jointly with the SMK Corporation, an electronic components manufacturer, headquartered in Tokyo, the Kindai University research group developed a system to detect micro vibrations of the body using extremely high frequency (EHF) electromagnetic waves with wavelengths of only several millimeters, referred to as \u201cmillimeter waves.\u201d<\/p>\n
The Kindai group recognized that sensors for millimeter waves are relatively inexpensive, and as such are widely used (without much recognition) in the management of animals\u2019 health, in the monitoring of plant facilities in high-temperature environments, and in security systems, vehicle safety devices, etc.<\/p>\n
In its work, the research group determined respiratory movements of 20 volunteers using a millimeter-wave sensor developed by SMK. Millimeter waves were emitted to each subject\u2019s thorax and abdomen, after which the movement of their body surface was visualized as a waveform based on the reflected waves. This was compared with conventional methods.<\/p>\n
The technique was able to accurately determine respiratory movements of babies and small children\u2014traditionally difficult to ascertain. Additionally, stable measurements were confirmed both when subjects were lying on their backs for a CT scan and standing for an X-ray.<\/p>\n
It can be difficult or impossible for a technician to tell a baby or small child to \u201cstay still\u201d or \u201chold your breath,\u201d complicating the effort toward an accurate diagnosis. Moreover, the assessment of respiratory motion by visual observation depends greatly on each technician\u2019s experience and expertise. In addition, making patients partially undress can cause embarrassment, which is another concern.<\/p>\n
The following features were noted by the research group as advantages of the new system:<\/p>\n
Given the potential of more accurate radiotherapy through the monitoring of respiratory motion in real time, the group plans to continue further applied research.<\/p>\n","protected":false},"excerpt":{"rendered":"
