  • Method for Extracting Acoustic Shadows to Construct an Organ Composite Model in Ultrasound Images

説明

<p>Ultrasound has a lot of advantages in observing diseased organ areas compared with other imaging diagnostic modalities. Nevertheless, the presence of acoustic shadows in ultrasound images can impede observation of the diseased area, and although the ultrasound probe can be moved to scan for obtaining ultrasound images that avoid the bones, this limits the current imaging field of view and viewpoint which is favorable to observe the affected area. To cope with these problems, we have designed a conceptual model with the aim of expanding the imaging range for organ diseased areas by compositing the images to complement areas with acoustic shadows. In this report, we propose a method for extracting the composited acoustic shadow element from the ultrasound images of kidneys on the basis of the principles of ultrasound image generation and qualities of bone-generated acoustic shadows. Experimental results show our proposed method extracts acoustic shadows with high accuracy.</p>
