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.
