- Method for detecting aspiration based on image processing-assisted B-mode video ultrasonography

抄録
We developed a computer-aided image processing technique to assist in the detection of aspirated boluses by clinicians using B-mode video ultrasonography（BV-US）movies. This study used 42 ultrasonography movies from a previous study that investigated the performance of aspirated bolus detection. This image processing technique aimed to assist clinicians in detecting aspirated boluses and the anterior tracheal walls from BV-US movies in which aspirated bolus appearances were emphasized. We combined a method that focused on the region of interest and the correlation coefficient between current and previous images to emphasize the characteristics of aspirated boluses from brightness-adjusted BV-US images. The sensitivity and specificity of this image processing-assisted method were 0.91 and 0.94, respectively, when we used simultaneously collected videofluoroscopy or videoendoscopy results as references. For four silent aspiration movies for which detection did not occur without assistance of image processing, detection was achieved with image processing assistance. Aspirated boluses detected only with image processing assistance had significantly smaller areas, shorter minor axes, longer major axes, and higher average brightness levels than those detected without image processing. This method will contribute to help clinicians provide modification of food viscosity and posture at an early stage for patients with dysphagia.
