Safe swallowing is a big challenge in the medicine and food industry. This challenge arises due to a lack of imaging modalities with sufficiently high spatial or temporal resolution. Therefore, we developed a numerical swallowing simulator (Swallow Vision) based on medical images. In this simulator, the organs shifted with time due to forced displacement, while the food flow was numerically calculated using the moving particle method. The results were verified by comparing VF images (Fig.). A literature review demonstrated that Swallow Vision was the first three dimensional swallowing simulator. This approach is a new and useful tool in the medicine and food industry.
