ABSTRACT
We developed a system to improve the quality of telemedicine, and the test results obtained have been presented in this paper, along with the technical details of the system. The spread of COVID-19 has accelerated the need for telemedicine to effectively prevent infections. However, in traditional Japanese medicine (Kampo), where color is essential, an accurate diagnosis cannot be made without color reproduction. Because commercial smartphones cannot reproduce colors with the level of fidelity required for medical treatments, we created a color chart that includes the human skin and tongue colors to help doctors identify their colors accurately during a telemedicine examination. Further, we developed a telemedicine system that allows for automatic color correction using a mobile device, with a color chart and non-contact heart rate measurements.
ABSTRACT
The circumference of a limb is an important parameter in the follow-up of an edema. Recently, several methods of measuring the circumference on a limb using 3D cameras have been proposed. However, the 3D cameras used are expensive and difficult to implement in general medical facilities. In this study, we propose a circumference-measurement method using a Structure Sensor. First, the leg is photographed and unnecessary background objects are removed from the obtained point cloud. Next, a cross-sectional view is obtained by slicing the point cloud at the specified leg height. Finally, the circumference measurement at a specified leg height is performed by calculating the circumference using the acquired cross-sectional view. Using this method, the leg circumferences of two healthy subjects were measured at two points. For comparison, circumferences were also measured with a measuring tape. The difference between the values estimated using our method and the measured values was generally less than 0.5 cm.
