Tool Localization in 3D Ultrasound Images

摘要: Real-time three-dimensional ultrasound has been demonstrated as a viable tool for guiding surgical procedures [1]. This visualization technique may enable range of new minimally invasive techniques in cardiac and fetal surgery. It is becoming increasingly clear, however, that instruments such endoscopic graspers when immersed liquids display artifacts irregularities make it difficult to determine the tool’s location, orientation, geometry (Figure 1a). In addition, instrument’s shape can appear incomplete due its orientation or obstacles field. Since properties these are known priori, feasible combine this information with image data locate render an enhanced representation instrument. paper introduces preliminary study enhancing ultrasound, focusing on relationship between tissue
