Abstract
It is known that elderly people's pneumonia caused by swallowing disorder contains high danger of death. However, there is no medical instrument to detect the aspiration. Here, we applied ultrasonic 2-D images and some care foods for patients to detect the aspiration. Three care foods used here were jerry, yogurt, and moose-up. The clear ultrasonic 2-D images were obtained for moose-up. The moose-up was prepared by mixing soluble powder and liquid, and the mixture had high viscosity and ununiformity of density. The results obtained here suggested that the ultrasonic 2-D images for the viscous liquid care foods would enable the detection of aspiration.
